What causes too much foam in the washing machine?
Excess foam is almost always a detergent issue rather than a machine fault. The most common cause is using too much detergent for the water hardness or load size. Counterintuitively, using too little can also cause some extra foaming because front-loading detergents contain anti-foaming agents that need to be present in sufficient quantity. The fix is using the correct amount for your water type.
Excessive foam inside the washing machine looks alarming but is rarely a sign of a machine fault. It can, however, cause real problems if severe enough – including preventing the machine from draining and leaking suds out through the door or dispenser drawer.
Why Too Much Foam Is a Problem
What excessive foam causes
- Foam can leak from the machine – through the door seal, the soap drawer, or steam vents
- Heavy foaming can prevent the pump from draining the water correctly
- Too much foam cushions clothes from rubbing against each other – which reduces cleaning effectiveness. Mechanical agitation is a core part of how washing machines clean laundry
- Foam in the drum during spin can contribute to spin imbalance and machine noise
Causes of Excess Foam and How to Fix Them
Too much detergent
The most common cause. The correct quantity is specified on the detergent packet and varies with water hardness and soil level. Soft water areas require less detergent than hard water areas. Check the dosing guide on the packet and compare it to how much you are actually using.
Too little detergent
Counterintuitive but real – front-loading washing machine detergents contain anti-foaming agents. If too little detergent is used, there may not be enough anti-foaming agent present, which can cause some additional foam. This is less dramatic than the excess from too much detergent but worth knowing if you have been reducing dosage trying to fix the problem.
Water softer than expected
Soft water produces more foam from the same quantity of detergent than hard water. If you have moved to an area with softer water, or if your water supply has changed, the same detergent dose that worked before may now be excessive. Check your water hardness with your local water company and adjust the dosage accordingly.
Anti-limescale products over-softening the water
Products such as Calgon and similar anti-limescale tablets soften the water inside the machine during the wash. If you use these in a hard water area, you should use the detergent dosage specified for soft water – not hard. Using the hard water dose with an anti-limescale product effectively means you are using too much detergent for the actual water softness during the wash cycle. See our guide on whether Calgon is worth using.
Overloading the drum
An overloaded drum restricts rinsing – soap suds from the main wash cannot be fully removed because the laundry is packed too tightly for water to circulate effectively. The residual suds then become visible during the spin cycle. See our guide on how to load a washing machine correctly.
Machine Won’t Drain Due to Excess Foam
If the foam is so heavy the machine cannot pump out the water, do not keep running the drum – the agitation and pumping action whips the foam up further and makes the situation worse.
-
Try fabric softener first. Pour a cap-full of fabric softener into the dispenser drawer and flush it through with cold water. Fabric softener reacts with and suppresses foam relatively quickly. Wait a few minutes and check whether the machine can now drain.
-
If that does not work, flush with cold water manually. Without running the machine, pour cold water directly into the drum in large quantities. Lower the drain hose to allow this water to drain by gravity. Raise the hose and repeat. This dilutes the foam progressively without the drum agitation making it worse. This takes time but is effective.
-
Once foam has subsided, run a rinse-only cycle to clear any remaining detergent from the machine and laundry before running a normal programme.
Foam Only on Rinse and Spin
If excess foam is only visible during rinse cycles or spin – not during the main wash – a partial pump blockage is the likely cause. A partial restriction in the pump or filter allows enough water to drain to trigger the spin, but not fast enough to fully remove the soap suds from the main wash. These then get whipped up again during the spin.
Clean the pump filter first. If that does not resolve it, see our guide on washing machine not draining properly for further diagnosis.

Frequently Asked Questions
Why is there too much foam in my washing machine?
The most common cause is using too much detergent for the water hardness. Soft water produces more foam from the same dose than hard water. If you use anti-limescale products such as Calgon, these soften the water further and you should use the soft water dosage on the detergent packet, not the hard water dosage. Using too little detergent can also cause some foam because front-loading detergents contain anti-foaming agents that need to be present in sufficient quantity.
Can too much foam stop the machine from draining?
Yes. Very heavy foaming can prevent the pump from draining effectively. Do not keep running the drum if this happens – the agitation makes the foam worse. Pour a cap of fabric softener into the dispenser drawer and flush with cold water to suppress the foam, or manually flush cold water through the drum by lowering and raising the drain hose repeatedly to dilute the suds without agitation.
Why do I only get foam on rinse and spin?
A partial pump or filter blockage is the likely cause. The restriction allows enough water to clear for the machine to proceed to spin, but not enough to fully remove the soap suds from the main wash. These then foam up again during the spin cycle. Clean the pump filter as a first step.
I reduced the detergent dose but still have too much foam – why?
If you have reduced the dose significantly, you may now be below the threshold needed for the detergent’s anti-foaming agents to work properly. Front-loading washing machine detergents are designed to produce minimal foam, and they contain agents specifically to suppress it – but these only work correctly at the right dosage. Check the packet for the correct quantity for your water hardness and use exactly that amount.
Whites coming out of washing machine looking grey coloureds losing colour
Whites going grey and colours fading prematurely are usually caused by using the wrong type of detergent, using too little detergent, or overloading the machine. Detergents with optical brighteners and bleaching agents keep whites white but fade colours – colour-care detergents protect colours by omitting these agents. Using both types, matched to the load, is the correct approach for consistently good results.
Detergent Type Is the First Thing to Check
Washing machine detergents are not interchangeable. The chemistry that makes a detergent effective for whites actively damages coloured laundry, and vice versa.
For whites – use a detergent with bleaching agents
Detergents for whites contain optical brighteners and bleaching agents (often oxygen bleach or enzymes) that break down yellowing and restore brightness. If white laundry is coming out grey, this is typically because a non-whites detergent is being used, the detergent dose is too low, or the wash temperature is too low to activate bleaching agents effectively.
For colours – use a colour-care detergent
Colour-care detergents omit the bleaching agents that whites detergents rely on. They are formulated to protect dyes and prevent fading. Using a standard whites detergent on coloured laundry over time will cause progressive fading – it extracts colour with every wash. A dedicated colour detergent slows this significantly.
The practical implication is that one detergent cannot do both jobs well. Most households should keep both a whites detergent and a colour-care detergent and select based on the load. Many families find it convenient to have a standard wash detergent for mixed colour loads (which performs adequately for neither whites nor colours specifically) and dedicated detergents for white-only and colour-heavy loads.
Why Detergent Dose Matters
Using less detergent than recommended is a common way to reduce costs but it creates problems that ultimately cost more to fix.
Poor cleaning results
An insufficient dose of detergent cannot hold soiling in suspension effectively – some re-deposits onto fabrics during the wash. This shows as a gradual greying of whites and a general dullness to all laundry. It also allows grease and grime to accumulate inside the machine rather than being flushed away. Check the door seal and the drum interior regularly for slime or black mould build-up. See our guide on washing machine smells and internal cleaning.
Limescale damage to the heating element
Washing machine detergents contain water-softening agents that protect the heating element against limescale. Using too little means these protective agents are not present in sufficient concentration. Limescale gradually coats the heating element, reducing its efficiency and eventually causing it to fail – an expensive repair that a correct detergent dose helps prevent. In hard water areas this effect is accelerated. See our guide on limescale in washing machines.
Overloading Makes Everything Worse
An overloaded washing machine cannot agitate laundry effectively – items do not tumble freely through the water and detergent solution. The result is uneven cleaning, poor rinsing (detergent residue remaining in fabric), and reduced effectiveness of whatever detergent is used. If the drum is full to the top with no room for laundry to move, the wash result will be poor regardless of detergent quality. See our guide on how to load a washing machine correctly.

Frequently Asked Questions
Why are my white clothes coming out grey?
The most common causes are using a colour-care or combined detergent instead of a dedicated whites detergent, using too little detergent (allowing soiling to re-deposit on fabric), washing at too low a temperature for the bleaching agents to activate, or overloading the machine. Check the detergent type first, then the dose, then the programme temperature. If the problem persists, inspect the drum and door seal for slime or residue build-up that may be re-depositing onto laundry.
Why are my coloured clothes fading in the wash?
Using a detergent with bleaching agents (typically marketed for whites or as “all-purpose”) on coloured laundry will cause progressive fading. Switching to a dedicated colour-care detergent will significantly slow fading. Also check that the water temperature is not higher than the fabric care label recommends – higher temperatures accelerate colour loss in dyed fabrics.
Can I use one detergent for everything?
A combined “all-in-one” detergent is a compromise – it is less effective at keeping whites bright than a whites-specific detergent and less protective of colours than a colour-care product. For households with predominantly coloured laundry and little white, a colour-care detergent works well for everything. For households with a mix, keeping both types and selecting by load gives consistently better results.
White streaks on laundry after washing
White streaks or powder residue on laundry after washing are most commonly caused by undissolved detergent – but can also be caused by gunge and limescale from a dirty door seal. To remove existing marks, try sponging the fabric, running a rinse-only cycle, or re-washing without detergent. To prevent recurrence, identify and fix the cause from the list below.
Common Causes and What to Do
Overloading the drum
Too much laundry prevents water and detergent from circulating freely. Powder can become trapped in folds of fabric and never fully dissolve. Reduce the load size and ensure there is room for items to tumble freely. If using a dosing ball or net in the drum, place it at the very top of the load and towards the back so water can reach it from the start. See our guide on how to load a washing machine correctly.
Not using enough detergent
Counter-intuitively, too little detergent can cause a whitish film on laundry. Detergents contain water-softening agents that need to be present in sufficient concentration to neutralise the minerals in hard water. If the dose is too low for the water hardness, these minerals can deposit on fabric as a pale residue that looks similar to undissolved powder. Always use the dose specified for the water hardness in the area – not the minimum dose.
Low water pressure – detergent not flushed from drawer
Low inlet water pressure can mean not all the detergent in the dispenser drawer is flushed into the drum at the start of the cycle. The remaining detergent then drips or falls onto laundry during rinsing when it can no longer dissolve fully. If water pressure cannot be improved, switch to placing detergent directly in the drum using a dosing container rather than the drawer. See our guide on low water pressure and washing machines.
Detergent placed in the wrong drawer compartment
The soap dispenser drawer has separate sections – typically a pre-wash compartment and a main wash compartment. The pre-wash compartment is flushed with cold water during pre-wash and rinsing phases, not the hot main wash cycle. Powder placed here may not dissolve properly and can be deposited onto laundry during the rinse. Always place detergent in the main wash compartment unless deliberately using a pre-wash programme. Check the instruction manual if the compartments are not clearly labelled.
Dirty or blocked dispenser drawer
A drawer with old detergent or fabric softener residue built up inside can restrict the flow of water through it, leaving powder partially undissolved. Remove the drawer and clean it thoroughly. Check the recess it sits in as well – the inlet jets above the drawer can also become blocked with residue and reduce the water flow that flushes detergent into the drum.
Gunge and limescale from the door seal
Marks that appear streaky rather than powdery, particularly on dark clothing, may not be undissolved detergent at all. Accumulated limescale and grease inside the door seal fold can loosen during a wash and deposit onto laundry. Lift the door seal fold and inspect for thick dark or grey residue. If present, a thorough machine clean – including the seal fold – is needed. Prolonged under-dosing in hard water areas is a common cause of this build-up. See our guide on washing machine grease, mould and smells.
Switching to liquid detergent eliminates undissolved powder entirely – liquid disperses immediately and does not suffer from the low-temperature dissolution issues that powder can. However, liquid detergents do not contain bleaching agents, which means white laundry may gradually grey over time, and the machine is more prone to grease and mould build-up without periodic powder or hot maintenance washes. Liquid detergent alone on cool programmes long-term is one of the leading causes of smelly and gunged-up washing machines.

Frequently Asked Questions
How do I remove white powder marks from clothes after washing?
First try sponging the affected area with clean water. If the marks persist, run a rinse-only cycle without adding any detergent. If that does not clear them, put the items through a short wash cycle on their own without any detergent. Once the marks are gone, identify and address the underlying cause to prevent recurrence.
Why is there white residue on dark clothes after washing?
On dark clothing, white residue is most visible and is most commonly caused by undissolved powder detergent, but it can also be limescale or gunge from a build-up inside the door seal fold. Inspect the door seal – if there is thick grey or dark residue built up inside the fold, this is likely the source. The door seal requires thorough cleaning. Also check detergent dose, drawer cleanliness, and load size.
Can too little detergent cause white marks?
Yes. In hard water areas, detergent contains water-softening agents that must be present in sufficient concentration to prevent mineral deposits. An insufficient dose leaves these minerals free to settle on fabric as a pale whitish film. This can easily be mistaken for undissolved powder residue. Always use the dose recommended for the water hardness in the area – not the minimum on the packet.
Rust coloured spots on laundry
Brown or rust-coloured spots on laundry after washing have three main causes: metal objects left in pockets rusting inside the machine, iron or rust in the water supply, or failing drum bearings allowing water to rust the bearing assembly. Work through each cause systematically – the most common is a forgotten metal item inside the outer drum.
Cause 1: Metal Objects Left in Pockets
Nails, paper clips, coins, and other small metal items left in pockets can pass through the drum holes during washing and become lodged in the space between the stainless steel drum and the outer tub. Once there they cannot easily circulate and are constantly exposed to water. They rust, and this rust deposits onto laundry during subsequent washes.
-
Check the pump filter first.
Small metal objects sometimes make it as far as the pump filter. Remove and inspect it – instructions for finding and accessing the filter are in our guide on washing machine pump filters.
-
Look through the drum holes with a torch.
Rotate the drum by hand and shine a torch through the holes as they pass. Metal objects in the tub space are sometimes visible. If visible and close to a hole, they can sometimes be hooked out with a stiff piece of wire. If not accessible, disassembly is required.
-
Retrieve the object if found.
If the object cannot be reached through the drum holes, the machine will need partial disassembly to access the tub space. See our guide on removing objects stuck in the washing machine drum.
Cause 2: Iron or Rust in the Water Supply
Rust-coloured staining can come from the water supply itself rather than from inside the machine. This is more common in properties with older pipework, in rural areas with bore-hole water supplies, or when water has been standing in pipes.
-
Test the tap water. Hold a white piece of cloth under the cold water tap and let water run through it for several minutes. If a brown or rust-coloured stain appears on the cloth, iron or sediment in the water supply is the cause. -
Flush the pipework before running a wash. Run the cold tap for a minute or two before starting the washing machine. This clears water that has been standing in the pipes – which is where most sediment settles – and replaces it with fresher supply water. -
Check and clean the inlet valve filter. The inlet valve on the back of the washing machine has a small mesh filter inside the fitting where the fill hose connects. Turn off the water tap, unscrew the fill hose, and inspect the filter for sediment or rust deposits. Clean or replace if blocked. -
Contact the water authority if the problem persists. Consistent rust or iron in the water supply may indicate a problem with the mains supply or the property’s pipework that requires a plumber or the water supplier to investigate.
Cause 3: Failing Drum Bearings
A less common cause is rust from the drum bearing assembly itself. The drum shaft runs through sealed bearings. When the bearing seal fails, water reaches the bearings and they begin to rust. Over time this rust can deposit onto laundry.
If drum bearing failure is the cause of rust spots, the machine will almost certainly be making a loud rumbling or roaring noise on spin as well. This is the most reliable indicator that bearings are involved. See our guide on what noisy drum bearings sound like. Bearing replacement is a major repair and on many modern machines the cost approaches or exceeds the machine’s value.
Treating Rust Stains on Laundry
For mild rust stains
Cover the stain with salt, then squeeze lemon juice over it. Leave overnight and rinse thoroughly before washing normally. The combination of citric acid and salt is a traditional and effective treatment for light rust marks on fabric.
Dedicated rust remover products are available for fabric use. These are more powerful than the salt and lemon method and are appropriate for older or more deeply set rust stains. Follow the product instructions carefully – some rust removers are not suitable for all fabric types.

Frequently Asked Questions
Why are there brown spots on my clothes after washing?
Brown or rust-coloured spots are most commonly caused by a metal object – a nail, paper clip, or coin – that has slipped through a drum hole and is rusting in the tub space. Check the pump filter first, then inspect through the drum holes with a torch. Less commonly, rust in the water supply or failing drum bearings can be the cause.
How do I know if rust in the water supply is causing the stains?
Hold a white piece of cloth under the cold tap and run water through it for several minutes. If the cloth takes on a brown or rust tint, iron or sediment in the supply water is the cause. Run the cold tap for a minute or two before each wash to flush standing water from the pipes, and check the inlet valve mesh filter for sediment.
How do I remove rust stains from clothes?
For mild stains, cover with salt and apply lemon juice – leave overnight, then rinse and wash normally. The citric acid in lemon juice dissolves iron oxide (rust) effectively on light marks. For heavier or older stains, a proprietary fabric rust remover is more reliable. Check that the product is suitable for the specific fabric type before applying.
Biological detergent and skin irritation
A review of 40 years of research on biological washing detergents, published in the British Journal of Dermatology, concluded that enzymes in biological laundry detergents are not a cause of skin irritation or skin allergy. Despite this, many people believe biological detergents cause itching or aggravate eczema. Other components of detergents – fragrances, preservatives, and residue from inadequate rinsing – may be more significant contributors to skin reactions.
What the Research Found
Researchers at universities including Nottingham and London conducted a review of 40 years of research into the biological agents (enzymes) used in biological washing machine detergents. Their findings were published in the British Journal of Dermatology.
“The balance of all the evidence is that enzymes in laundry detergents are not a cause of either skin irritation or skin allergy.”
British Journal of Dermatology – review of biological laundry enzyme research
The conclusion is that the biological enzymes specifically – the component that distinguishes biological from non-biological detergent – have not been shown in research to cause skin irritation or allergic reactions in normal domestic laundry use.
Some consumer advocates have noted that research into laundry product safety has at times been funded or commissioned by detergent manufacturers. This does not automatically invalidate the findings, but it is a factor worth noting when evaluating the strength of the conclusion. The National Eczema Society’s guidance on household irritants and eczema provides independent advice – see eczema.org household irritants.
Why Many People Believe Biological Detergent Causes Irritation
Despite the research findings, a significant number of people are convinced that switching from biological to non-biological detergent resolved skin irritation for themselves or a family member. This belief typically arises from a clear pattern: itching appeared, they changed detergent, the itching stopped.
If the enzymes are not the cause, what might explain this pattern? Several possibilities exist:
Fragrance and preservatives
Biological detergents often contain fragrances, optical brighteners, and preservatives that non-biological versions may not, or may contain in different concentrations. These are known skin sensitisers for some people. Switching to non-biological may have removed one of these components rather than the enzymes.
Detergent residue from poor rinsing
Any detergent remaining in fabric after washing can irritate sensitive skin. Modern washing machines use less water than older models and may not rinse as thoroughly, leaving residue in laundry. Adding an extra rinse cycle reduces residue regardless of detergent type. See our guide on washing machines and poor rinsing.
Dosing and concentration
Over-dosing detergent leaves more residue in fabric. Biological detergents tend to be more concentrated than non-biological equivalents. Using less detergent – the correct amount for the load and water hardness – reduces residue and may reduce irritation without changing detergent type.
Wash temperature
Biological enzymes are designed to work effectively at lower temperatures. At very high temperatures (above 60 degrees) they are denatured and inactive. If a particular skin reaction was temperature-related – from incomplete rinsing at low temperatures, for example – changing temperature alongside changing detergent type could account for the apparent improvement.
Practical Guidance for Sensitive Skin
-
Use fragrance-free detergent. Fragrance is a common skin sensitiser. Many biological and non-biological detergents are available in fragrance-free versions, which are generally better tolerated by people with sensitive skin or eczema. -
Add an extra rinse cycle. Reducing detergent residue in laundry by adding a second rinse is effective regardless of detergent type. Many machines include this as a programme option. -
Use the correct dose. Over-dosing leaves more residue in fabric. Use the amount recommended on the packet for the load size and water hardness in the area. -
Consult a dermatologist if symptoms persist. A dermatologist can patch test for specific allergens and identify the actual cause of a skin reaction. This is more reliable than trial and error with different detergent types.

Frequently Asked Questions
Does biological washing powder cause skin irritation?
Research published in the British Journal of Dermatology – reviewing 40 years of evidence – concluded that the enzymes in biological laundry detergents are not a cause of skin irritation or skin allergy. However, other components present in many detergents (fragrances, preservatives, optical brighteners) are known skin sensitisers. People who find biological detergent irritating may be reacting to these components rather than the enzymes specifically.
Is non-biological detergent better for eczema?
The research does not support the claim that biological enzymes specifically cause eczema flares. However, non-biological detergents are sometimes formulated with fewer potential irritants overall. The most evidence-backed approach for eczema-prone skin is to use a fragrance-free detergent – which is available in both biological and non-biological versions – and to use an extra rinse cycle to minimise residue in laundry. If symptoms persist, patch testing with a dermatologist identifies specific allergens accurately.
If biological detergent doesn’t cause irritation, why did my symptoms clear up when I switched?
Switching detergent involves more than just changing the enzyme content. Non-biological detergents may have different fragrance formulations, different preservative systems, or different concentrations. Any of these changes could account for an improvement. Alternatively, reducing the dose when switching, or improved rinsing, may have reduced residue in fabric. The enzymes themselves are unlikely to be the cause based on current research.
Stop bobbling or pilling on clothes
Pilling (also called bobbling or linting) is caused by friction damaging fibres until they separate from the fabric and form small tangled balls on the surface. It is most common on synthetic fibres such as polyester, acrylic, and nylon, which hold pills firmly. Prevention is easier than removal – washing inside out, using a mesh laundry bag for delicates, and avoiding tumble drying all reduce pilling significantly.
What Is Pilling?
Pilling, bobbling, and linting all describe the same thing: small tangled balls of fibre that form on the surface of fabric. They develop when friction – either during washing, tumble drying, or regular wear – breaks individual fibres away from the main fabric structure. The loose fibre ends tangle with each other and form the characteristic pill or bobble.
Synthetic fibres (polyester, acrylic, nylon) pill most visibly because the broken fibres are strong enough to stay attached to the fabric surface rather than washing away. Natural fibres (cotton, wool, linen) do also pill, but the broken fibres tend to detach and wash away rather than clinging to the surface. In mixed-fabric washes, pills from natural fibres can transfer onto and stick to synthetic items in the same load.
What Causes Pilling
Friction is the single cause. It comes from three sources:
Wear and use
Repeated rubbing during normal use – areas where clothing contacts itself or other surfaces – causes fibres to break down over time. Collar edges, cuffs, underarms, and inner thighs of trousers are the most common wear-related pilling zones. Bedding that experiences sustained friction (such as a pillow case pressed between knees overnight) pills rapidly on both faces.
Machine washing
The agitation of items tumbling against each other in the drum generates friction. Synthetic and delicate fabrics are most affected. Washing at high spin speeds, with a full load where items have less room to move freely, or on programmes with aggressive agitation all increase pilling from washing.
Tumble drying
Tumble drying generates significant friction as items tumble against each other and the drum at heat. It is one of the most effective ways to accelerate pilling. Line drying eliminates this entirely.
How to Prevent Pilling
-
Wash items inside out. Turning garments inside out before washing means the outer face – the visible surface – experiences less direct friction from other items in the drum. The inside of the garment is less visible and pilling there is less noticeable. -
Use a mesh laundry bag for delicates and synthetic items. A zipped mesh bag reduces direct contact between delicate or synthetic items and the rest of the load, significantly reducing friction-based pilling during washing. -
Use a cooler, gentler wash programme. A delicate or synthetics programme with lower agitation and a reduced spin speed reduces friction during the cycle. Washing at 30 degrees rather than 40 also reduces fibre stress. -
Do not tumble dry items prone to pilling. Line drying eliminates the significant friction of tumble drying. Light ironing can restore smoothness to items that have been line dried and feel stiff. -
Do not overload the machine. A correctly loaded drum allows items to move freely rather than being compressed against each other. Overloading increases friction between items. See our guide on how to load a washing machine correctly. -
Choose better quality fabrics where pilling matters. Higher-quality fibres with tighter weave or knit structures are more resistant to pilling. Tightly twisted yarns pill less than loosely twisted ones. This is a purchasing consideration rather than a laundry technique.
Fabric softener is sometimes recommended to reduce pilling by lubricating fibres. It is added during the final rinse – after the main wash agitation has already taken place. Its effect on pilling during washing is therefore limited. It may help slightly by reducing static charge that makes pills cling to synthetic fabric surfaces, but it is not a primary prevention measure. Prevention through washing technique makes a greater difference.
How to Remove Existing Pills
Effective removal methods
- Fabric shaver (lint remover): A battery or mains-powered fabric shaver is the most effective tool for removing established pilling. The rotating blade cuts the pills from the surface cleanly without damaging the underlying fabric. Available at most supermarkets and online
- Sticky lint roller or tape: A lint roller or Sellotape pressed and lifted over the surface removes loose and lightly attached pills effectively and quickly
- Careful trimming: Individual prominent pills can be cut away with small scissors or a disposable razor blade held flat against the surface – requires care to avoid cutting the base fabric
Less effective or risky methods
- Wet nailbrush: Can work on some fabrics but risks pulling and distorting the weave on delicate items – use with caution
- Picking by hand: Very slow for significant pilling and can pull undamaged fibres from the fabric in the process
- Washing again: Does not remove existing pills and may add more

Frequently Asked Questions
What causes bobbling on clothes?
Bobbling (pilling) is caused by friction breaking individual fibres away from the fabric. The loose ends tangle together and form the characteristic small balls on the surface. It happens during wear, machine washing, and tumble drying. Synthetic fibres (polyester, acrylic, nylon) are most prone because the pills stay attached rather than washing away. Higher agitation, overloading, tumble drying, and lower quality fabrics all increase pilling.
How do I remove bobbling from clothes?
A fabric shaver (lint remover) is the most effective tool – it cuts pills from the surface cleanly without damaging the fabric underneath. A sticky lint roller or tape removes loose and light pilling quickly. Individual prominent pills can be carefully cut with small scissors. Avoid picking by hand as this can pull undamaged fibres from the fabric.
Can washing cause bobbling on clothes?
Yes. Machine washing generates friction as items tumble against each other in the drum. Synthetic and delicate fabrics are most affected. Washing items inside out, using a mesh laundry bag, choosing a delicate or low-agitation programme, and not overloading the drum all reduce washing-related pilling.
