Why can’t modern washing machines rinse properly?

Soapy-water My attention was drawn to rinsing efficiency after noticing that out of dozens of washing machines reviewed by Which? most of them had a poor rating for rinsing. Even some which were singled out as a Best Buy had been poor at rinsing, and believe it or not at least one Best Buy was “very poor” (accurate at time of writing). I found that pretty shocking.

From studying the figures it is clear that if “good”, or “very good” rinsing was one of the prerequisites for a Best Buy there would be no Best Buy washing machines or washer dryers at all – not a single one. It appears that Which? have decided to allow the poor rinsing results to be a caveat instead of a best buy killer. Please note however that several Which? best buys are “satisfactory” at rinsing which is something at least.

Out of 125 washing machines and washer dryers tested, a remarkable 75 of them (60%) were rated either “poor” or “very poor” at rinsing with only 3 getting the rating we should expect for all washing machines which is “good”. The rest were a mere “satisfactory”. To summarise, just less than 3 % of the 125 washers & dryers are “good” at rinsing according to Which?

[update] Since writing this article I’ve discovered Which? no longer give the majority of washing machines 1 or 2 star ratings for rinsing ability, and the majority appear to get 3 or 4 stars. Which? tell me they’ve readjusted their rinse marks to more accurately reflect the degrees of abilities between even poor rinsing machines. However, they are still critical of many of their rinsing abilities in the comments and the pros and cons.

What does this mean?

Well for a start it doesn’t mean that we can settle for one of the three washing machines that are “good” at rinsing because they unfortunately let themselves down in other areas such as with “noisy spin, and poor brand reliability”. However, if you really need a washing machine that rinses better than any other – maybe because of allergies – then at least Which? have identified three candidates out of the 125 they’ve tested so far. I have to advise though that you should go for them only if good rinsing is your most important requirement and are prepared to accept big compromises elsewhere – as long as it rinses well.

Why aren’t washing machines rinsing properly and does it really matter anyway?

Surely all washing machines should rinse well? It’s surely quite simple, you just use enough water to rinse them properly. It’s astounding that we have reached the situation where the majority of washing machines and washer dryers on sale in the UK are apparently poor at rinsing.

Save-water This has probably come about because people have been focussing on other aspects, which has left rinsing as a low priority. Two explanations spring to mind. Firstly, the focus on using less and less water is clearly impacting on our washing machine’s ability to rinse effectively. Whereas modern detergents can facilitate efficient and effective washing results at lower temperatures and with less water, no such product is currently allowing effective rinsing with much less water. Good rinsing needs plenty of water which is in direct opposition to the current environmental concerns and clamour to be the washing machine using the least amount of water.

Eco Labels

Eco Labels

The second explanation I can think of is that the eco-labelling system which awards ratings for energy efficiency, spin efficiency and wash efficiency do not appear to take into account rinse efficiency. As such, manufacturers aren’t being judged on how well their washing machines rinse, only on how well they wash and how well they extract water on spin. I’m speculating at this stage, but I can’t see how so many washing machines could be awarded an “A” wash efficiency rating if the tests took into account how well the clothes were rinsed. Presumably, as long as all stains are removed and laundry looks “clean” no one bothers about how much soap detergent residue is left.

It might be a good idea to create a fourth category, “rinse efficiency” on the eco labels, or at least include the rinse efficiency as part of the wash efficiency test.

Allergies Ultimately if customers don’t notice an issue then it could be argued that it doesn’t really matter. Maybe it doesn’t for most people, but it surely does to anyone sensitive to wash detergents and with allergies and a lot of people are. There were 581 comments added on this topic from such people before I had to close comments to prevent it being endless.

The current situation is that to anyone keen to buy a washing machine with good rinsing I have no washing machine to recommend because none of the companies producing the best, and the most reliable washing machines currently supply one that rinses above average according to Which? (although this could easily change and you would need to check out the latest to be sure.

Are Which? wrong?

Are Which? being too critical? Are Which? applying too stringent a rinse test? I must admit I’ve not had many complaints from people saying their washing machine isn’t rinsing properly and my own Miele washing machine, which although a Which? Best Buy, didn’t receive a “good” rating for rinsing yet it appears to rinse perfectly well as far as we can see. In fact I remarked to my wife that my clothes don’t smell of detergent like they used to in the old washing machine and deduced that it rinsed much better. However, neither of us have any reactions to washing machine detergent.

The thing about Which? is that they are totally independent. They work only for their subscribers interests and are actually a registered charity. They don’t make any money by recommending any product (even though they could) because they want to be seen as 100% unbiased. They are highly respected and I expect they test products fairly.

I suspect Which? are right and that modern washing machines don’t generally rinse very well because of the reasons I speculate about above. Whether it matters or whether it will change depends on whether enough of the public are bothered, or even notice. The 581 comments added to this article below show that many people do find this a big issue.

Which? research

NOTE: Which? do rate some washing machines as “satisfactory” for rinsing and even a couple are rated as “good” although unfortunately the few rated good (so far) are not so good on reliability.

Which? are constantly reviewing washing machines so if rinsing is particularly important to you it makes sense to become a member and see all the buying advice. I can’t print their advice for copyright reasons.

Here’s how they describe their reviews –

“We are of course well known for our traditional product testing. And when we test something like the proverbial washing machine, we will ask the laboratory not only to measure how clean the clothes get, but how much water and energy is used? How easy is it to work out the programmes? What is the machine like on specialist cycles? How long does it take? All these things feed into our best buy criteria. We will devise the testing schedule by looking at things from the ordinary user’s point of view: and if standard industry methods are not good enough we will devise our own methods”

Causes of poor rinsing

There are some common causes of poor rinsing even in washing machines that do rinse well that it might be useful to point out. Anyone experiencing poor rinsing problems where washing comes out with detergent residues or white powder streaks should read this –

    Rinsing Capabilities of Washing Machines.
    We heartily endorse these conclusions. For thirty years we had a succession of Hotpoint top loading machines which produced clean washing with little detectable powder residue using Persil . Towels were clean, soft and fluffy. Terry nappies could be washed and sterilised using the hot wash. These machines used full measures of washing powder and large quantites of water. When the last machine was beyond repair we purchased a Hotpoint Ultima WF 860. This has the energy and water economies now deemed necessary. However we immediately noticed that the towels were hard and the bedding activated breathing allergies.

    Washing powder was reduced to the absolute usable minimum, about a table spoonful for a full load. Subsequent experiments, with care not to overload the machine, extra machine rinses, rinsing in the sink by hand and subsequent spinning in the machine have produced the following conclusions :
    * Towels retain the most powder residue, the water in the sink becomes totally cloudy even after two extra machine rinses. The fluffy texture previously produced cannot be replicated, even using a good tumble drier. Towels hung out to dry without any tumbling dry like board.
    * Heavy cottons like sheets retain large mounts of powder residue unless rinsed in the sink.
    * Light cottons like underwear retain less, but can still irritate unless hand rinsed.
    * Artificial fibres retain the least powder residue.

    The problem can be diminished by using Ecover liquid wash, but this is not suitable for all washes.
    Ecoballs, or the Lakeland equivalent do not leave residue, but the fabrics are often harsh, and stains are left despite the use of the stain removing cream supplied. The application of this is a fiddly extra job.

    Through the good offices of John Lewis who supplied the machine two Hotpoint engineers visited us, and were both surprised by the amount of powder residue revealed in hand rinses. The machine was deemed to be working satisfactorily by the manufacturers.

    It would seem to us that controlled experiments under laboratory conditions are necessary to measure the amount of powder residue left in fabrics by modern washing machines. Those with skin or respiratory allergies are at risk from the present generation of machines which may be energy efficient and use little water, but do not rinse clothes effectively.

    P & E Kenyon.

    I agree with the statement about not rinsing properly, I repair appliances for a living and have a 30 year old Hotpoint top loader myself, It is far more reliable than any new machines and far easier to repair. But the main thing is it washes and rinses better than any other machine I have tested, and I have tested them all. Also it will complete a 60 degree whites load in under an hour if the water going in is hot enough, and the towels are WHITE!! not shades of grey. My work jeans go in on a 40 degree wash covered in grease etc and cutting oil and come out clean after only 45 mins. The only down side to this is the water consumtion, but that is more than compensated for by the reliabity and longevity of the machine itself. I have many customers to
    whom I have supplied reconditioned top loaders to replace new machines that just arent doing the job they are supposed to.


  3. avatar says

    Top loading washing machines do use a lot more water than front loaders although Which?* don’t rate them very highly saying none of the ones they tested were good enough to be best buys.

    They do tend to be more reliable too but they cost more to run. The extra water usage probably does make them rinse better. Each time a “problem” is addressed it causes another as in this case where the “problem” of using too much water is solved at the expense of reducing rinsing efficiency significantly.

    Couldn’t agree more about the poor rinsing of modern washing machines. When my fifteen year old machine died, I bought another and had vague suspicions that it wasn’t rinsing properly. Quite by accident, my suspicions have been proved correct by a newly purchased set of Ecoballs, which require no detergent. The first time I used the balls on towels which had previously been washed tradionally, I was horrified to find that the machine was filled with foam and I had to do two extra rinses even though I had used NO DETERGENT. To think that we were using these ‘clean’ towels to dry ourselves, when all along we were smearing ourselves with chemicals. My daughter has mild eczema and I am interested to see if this clears up.
    I have been using the Ecoballs for a fortnight now and so far find them to wash perfectly satisfactorily, except for my dishcloths which tend to pong a bit, although a quick soak in a mild bleach solution seems to have solved the problem. It is true that the Ecoballs aren’t perfect – it doesn’t remove stains and you must use a stain remover – but at least my washing isn’t chemical-ridden.

    I have a 20 yr old Hotpoint 9520 which had no repairs appart from brushes in all that time. Whilst having to ultimately renew the drum bearings/spider etc I decided to get a new backup machine. I chose a Bosch WEA 24162 not thinking about rinsing efficiency. I am very unhappy with the rinsing of the Bosch. The washing smells stronly of detergent even after 1 or 2 additional rinses and using the extra water button. I completely agree with your opinions and am at a loss as how to pick a suitable machine. For me poor or inadequate rinsing is a major drawback which it seems all current machines suffer. I tend to wash all important things, towels etc in the old Hotpoint and socks, jeans etc in the bosch if I use the Bosch at all. By the way Bosch say its not a problem and I must use a certain powder to avoid undisolved powder which I noticed on the door seal. I’d rather have properly rinsed washing and forgo washing the car to be environmentally friendly.

    Kevin, if rinsing is an important issue you should check out the Which? washing machine and washer dryer guides, each of which has a rinsing rating. These are affiliate links, which help Washerhelp and Whitegoodshelp if used (at no cost to the user) but I can honestly say that after being a member of Which? online for over a year now I would not buy any expensive product without checking them out first – Which? £1 trial offer – what’s the catch?.

    My son has eczema and therefore I need a washing machine that rinses well. I too have noticed that my aeg electrolux washing machine despite being a best buy still shows soap suds in the machine from a previous wash if I put a washing load in without detergent.
    I usually have 2 washing machines due to having 3 children as it is easier to get through the laundry quickly. My new 9kg best buy Bosch washer despite only owning it for just over 3 weeks has now broken as the rubber door seal pulled away and got tangled in a pair of trousers! The company I bought this from have agreed to replace the machine but this model has now been replaced or discontinued . I am unsure which model to replace it with as this company do not sell siemens washers which seem to be the only other usually reliable brand that is reasonable at rinsing..

  8. avatarNikki Jenkins says

    This Which article and the resulting comments have made me SO cross. About 10 or so years ago I discovered that modern automatic washing machines just do not rinse properly – full stop, end of story. I reached this conclusion following a long period of time, during which my young daughter developed eczema, I was scratching my shins raw to the point where they were bleeding, and our bed linen was covered in blood where my husband had scratched himself raw round his neck, chest, back and legs. I deduced this was caused by biological washing powders, but changing to non-bio made no difference. I then decided to test that the machine was rinsing by plunging a towel into a bowl of hot water – well, it was as if it had never been rinsed! Then followed about 6 years of arguing with Bosch that their washing machines didn’t rinse properly, engineers coming out – one idiot told me that the white soapy froth in the water was surfactant! I pointed out to him that surfactant IS soap, stupid man – we ended up with John Lewis replacing the Bosch with a Miele, but the problem is still there. The scientific fact of the matter is that to remove detergent from clothes you need two things : warm or hot water AND plenty of it. Modern washing machines have neither – you cannot buy a modern machine that rinses in hot water, and neither can you buy a modern machine that uses sufficient amounts of water.

    So I have to spend hours of my precious time rinsing, rinsing and rerinsing laundry by hand, spinning it out in the washing machine, and then starting the process all over again over and over again to get rid of the soap. For the last 3 years I have been too busy to do this, the result is that all our clothing and linen has a massive soap build up again, we are scratching ourselves to death, and I now have got a huge problem once again trying to rid my laundry of detergent.

    It is absolutely ridiculous – AND to add insult to injury I wrote to Which and told them about this all those years ago and they basically said they couldn’t understand what I was talking about, that their tests showed that modern washing machines were very good at rinsing.

    What a load of tosh !

  9. avatarSorry to be a party pooper says

    Sorry to be a party pooper but I am a bit concerned that some important factors are being left out of this discussion.

    If I recall correctly, Which tests rinsing by measuring the alkalinity of the water (detergent is alkaline) and also comparing the results to a high speed 2,800rpm industrial spinner. Tests like this are good and have indicated rinsing is frequently poor.

    However, some of the home tests posted here seem to judge rinsing by foam or suds. Suds must be present for genuine soaps to clean but suds do not have to be present for detergents to clean. In the case of a detergent, suds are still useful as an indcator during the wash that some active detergent is left over and therefore there is not a shortfall. But foam is actually a problem in the actual wash part of the cycle. It prevents proper wetting of the fabric, buffers the fabric from a physical agitation, limits the passage of dirt from fabric, etc. Foam is unwanted during the actual wash, so foam inhibitors are an ingredient of laundry detergents.

    When the foam inhibitor gets removed by the rinsing then left-over detergent will create lots and lots of suds. They are usually thin and wispy suds. So paradoxically, as fabrics are rinsed and rinsed (particularly if they are rinsed a lot) after the washing part of the cycle then suds often increase.

    Some posts mention how suds appear when washing towels without using any detergent at all. I agree there must be some detergent but it may be so little and be so dilute as to not be particularly significant. (Of course, the person with eczema can not tolerate even this much but many people can.)


    I might add an observation to posting by Nikki Jenkins (13NOV2007) in which Nikki takes her visiting Bosch engineer to task for saying what could be seen was only surfactant. To slightly over-simplify, not all surfactants are detergents. Laundry fabric conditioners are surfactants (usually cationic) but they are poor at cleaning. The majority of household liquid disinfectant is also surfactant. So are many hair conditioners. In fact, if a washing machine is foaming over due to incorrect detergent dosing then adding conditioner (a surfactant) to the detergent water (mainly surfactant) will dampen down the foam quite significantly.


    Just to make life a bit more complicated, some formulations of laundry detergent (Tesco Liquid Bio comes to mind) actually do contain quite a large proportion of genuine soap whereas something like Persil Liquid Bio contains much less. This gives washing machine “foam watchers” an extra challenge in order to determin whether rinsing has been done properly.


    All this is by way of saying that suds can be a very poor indicator of good rinsing. (And that knowing a little about detergents can cause misleading conclusions.)

  10. avatar says

    Party pooper? I wouldn’t say that was the case at all. Your comments are welcome and you sound like you have knowledge on the subject. However, If you say that the Which? tests are good, and do indeed indicate rinsing is frequently poor then there’s a reasonable chance that the presence of suds people have reported is an indication of poor rinsing.

    You make an important point that the presence of suds is not necessarily an indication of poor rinsing although it’s confusing as logically if thoroughly rinsed everything should be removed.

    I remember hearing that the suds are added for the consumer only, as they don’t like it when they can’t see soap suds, which they equate to cleaning. As you say, they are not necessary at all and in fact inhibit cleaning.

    The whole issue is a puzzle because how can someone judge if their washing machine is rinsing properly other than if the rinse water is clear? I even read an article in the paper the other day that says researchers have found that detergent doesn’t cause skin irritation or allergy – even biological detergent ( Biological detergents not guilty? Biological enzymes do not cause skin irritation ).

    At the end of the day Which? tests say that most washing machines are poor at rinsing which should be unacceptable. The trouble is, I don’t get many people complaining about poor rinsing so maybe it’s purely theoretical in that they still rinse adequately for most people.

  11. avatarMay says

    I am fed up with the new general washer & I absolutely argree that modern washers are rubbish in rinsing. I had a Samsung silver nano last year which has a design fault of being too sensitive to balance the load in order to get to spin ( takes forever to finish one spin). Rinsing is terrible as well.

    I changed to Zanussi 1227 & I am very unhappy with it as well because it uses so little water. Many times I took out the load to check after it’s been washed a few minutes in the washer, to my annoyance, my clothes or towels etc are not even completely wet, ( I tried half load to full loading the washer). It uses more or less same amount of water for the rinse cycles. So obviously how such little amount of water can do a proper rinse? Even if you are not bothered with the soap being removed or not, if you look at the water of the last rinse, they still look murky with dirt particles!

    With the modern washers using very little water for rinsing, I noticed that in order to try to get so called efficient rinsing with little water, the washers are now programmed to have much longer spinning time in order to squeeze out as much water as possible from the load. With the laundry are fast spinned much longer; they get demaged or worn out more quickly; my new towels look as if they’ ve been used 10 years just after several washes!

    Everytime I do the laundry, I have to spend lots of time to add extra water through the soap dispenser to increase the water level. I am trying to find a old generation washer which would do a more decent rinse even if it’s second hand.

    Being a member of Thought Field Therapy (TFT)Association, I myself & many other fellow members have used TFT & various methods to test allergies for thousands of clients. Majority of people tested are found to be affected by most laundry products (detergent & conditioner) even though they are not aware of it at all, but their health are actually affected somehow. Few people get skin irritation by using them, but that doesn’t mean our health are not affected.

    Just by smelling clothes which has been washed with laundry products, our sympathetic nervous system immediately show some signs of being negatively affected; (this can be measured with some equipment). How much worse when our skin are constantly absorbing the toxins from the clothes we wear or from the bed linens we sleep on, day in & day out. Eco Balls are found to be much more tolerable by the people tested. Ecover range is better tolerated than other common brands, but every individual is different. I use Eco Ball myself.

    Many sources (eg: Dr Hulda Clark in her Cancer books) commented that most common personal & household products, including laundry products are cancerous or harmful. There are many internets sources give such informations.

    We live in a unavoidable toxic world with toxic food & substances every where; the modern generation of washers add more nonsense & harm!!!

  12. avatarTeri NZ says

    I have recently had my 4 mth old Bosch front loader replaced with an Electrolux toploader and have had no end of problems with residual washing powder build up. It has got to the point now where after every load I have to remove half the load and re-rinse, then put in said remaining 1/2 load and re-rinse also. The kids’ school uniforms (navy) don’t even look clean for the start of the week because of soap build up. I’ve tried everything – dissolving the powder (only using 1/3 of recommended amount) in hot water for an hour while previous loads are finishing, using liquid wash detergent (which apparently is a no-no because it’s a low suds machine), putting it down the middle, on the bottom (before washing goes in) and around top, hot load, warm load, cold load! NOTHING IS WORKING!!! I too have a child with eczema and he is starting to itch like crazy. You would think with all this modern technology at our fingertips they could sort out a decent machine with a proper rinse cycle or a decent powder that doesn’t cost the earth. As for my water-aid eco friendly machine – well it’s not so eco friendly or water aiding at all because I’m having to run it three times per load to effectively rinse everything through.

  13. avatarA VERY unhappy Miele customer says

    18 months ago, much against my husband’s advice because of the expense, I purchased a Miele washing machine because having done my homework I decided that the brand was definitely the best. I am bitterly disappointed by its inability to rinse thoroughly (I never for one moment investigated this possibility as my old machine rinsed perfectly). Despite trying every type of washing substance, powder, tablets, liquid etc, it still fails to rinse. My husband who had slight eczema, is now having medical treatment in an attempt to reduce his symptoms. I daren’t tell him that I believe the washing machine is to blame or I wouldn’t hear the end of it!! Cannot believe that this brand, I paid £800 for my model, fails to live up to its reputation in this area. Sadly I cannot afford to replace the machine and have resorted to using the tiniest amount of detergent at the expense of best cleaning results.

  14. avatar says

    Of all washing machines you would expect Miele to be the best performance-wise not just in build quality. I wrote my article after learning that even miele washing machnes were often “poor” at rinsing according to Which? However, as pointed out in my article the majority of people don’t seem to have a problem with the standard of rinsing modern washing machines give.

    If people are allergic to detergent though it is a different matter although I’m not sure how anyone can know for sure it is the washing detergent causing the irritation as it’s a complex issue ( Biological detergents not guilty? -Biological enzymes do not cause skin irritation )

    Here is a useful PDF guide from the UK National Eczema Society regarding Main factsheet – washing clothes which may be useful to anyone with this issue.

    Do you use fabric conditioner? That potentially could cause irritation but the blame may be assumed to lie with the detergent. The thing about fabric conditioner is that it doesn’t get rinsed off properly as it only goes into the machine on the very last rinse.

    It’s also possible that something in the detergent you use has changed since aquiring the Miele and that could account for the increase in problems.

    At the end of the day the washing detergent manufacturers have some responsibility here and as one of the items in the eczema society article points out, detergent manufacturers should have customer helplines for anyone with allergic reactions to their products which should be looked into.

    Have you tried something like Dreft by the way? Advice from the eczema society regarding washing detergent is, “wash clothes in the minimum effective quantity of non-biological, un-perfumed washing powder. Give clothes an extra rinse. Avoid fabric conditioners.”

    I’m not too sure that using less detergent is necessarily beneficial as it would affect wash efficiency which could alow other things to cause irritation and combined with low temperature washes could allow bacteria to build up. It will also stop the water softening agents working properly which could cause damage to the washing machine through limescale over a period of years. However, if reducing quantity has definitely helped it’s probably the less of two evils.

    House mites can also cause problems and they can survive low temperature washing as a previous article of mine points out Dust mites and washing machines

  16. avatar says

    Matt: There’s a few mentions of eco balls on Whitegoodshelp you might want to look at Search for eco balls

    My understanding though is they don’t contain chemicals, which is why they are eco friendly. There are probably various versions knocking about these days, what are yours called? “Eco Balls” are the original and a trademarked name.

  17. avatarmatt says

    they are the original brand eco balls and they do list chemicals i think(?) I wonder what the co ball company has to say about this (im in agony here)

  18. avatar says

    Here’s a quote from the review –

    “The principal claim made by the manufacturers of these products is that they machine-wash your clothes without any additives at all. This, it is claimed, results from agitation of ceramic granules or the like, within the perforated balls which ionise (or is it de-ionise?) the water. The effect of this, it is said, is to lift dirt from your clothes, just as a detergent would, except without the harshness of chemicals that fade your clothes and require you to add softeners to your wash.”

  19. avatar says

    If you use a washing machine with nothing in at all it will usually still create some suds because of all the previous residue inside the machine, it could be that?. Eventually it should stop but it depends how long you’ve been using the eco balls.

  20. avatarmatt says

    i usually do a wash with nothing at all and it dosent create suds as soon as i took the eco balls out it stopped

  21. avatarFrustrated with technology!! says

    I have to run the “Rinse” programme after the machine has finished, it means I get extra rinses and the softener is dispensed during the last rinse on the “Rinse” programme.

    The disadvantages: the machine takes nearly an hour longer to finish and it increases the “wear and tear”, but I’d rather my laundry is rinsed properly.

    The clothes feel softer and don’t smell so strongly of detergent like they used to before I tried this method.

    Worth a try?

  22. avatar says

    It shouldn’t be necessary to run the entire rinse programmes again but with many washing machines you can’t select individual rinses any more. Many people actually like the smell of detergent and it’s specially perfumed to that end. If you have an extra rinse option button it’s worth trying that.

    Make sure you don’t overload which can reduce rinse efficiency.
