Best mattress cleaners

A mattress cannot be properly dried at home, which is why cleaning one is mostly damage limitation.

The honest answer to this question is uncomfortable. You cannot deep clean a mattress at home.

Water goes in easily and comes out slowly. A mattress is thick, dense and enclosed, and once moisture reaches the foam or the spring unit it can sit there for days. That is how you get mould inside a mattress, which is considerably worse than the stain you were treating.

So the useful advice splits in two. Prevent, with a protector, which costs 20 to 40 pounds and is the highest ratio of value to cost in bedding. And when something does happen, treat the surface only, with as little liquid as possible.

There is one more reason prevention matters: a stain voids most mattress guarantees absolutely.

Ergoflex LIFE Protector: Best protection overall

Mid range · 7.8 / 10

The highest scoring protector on this site at 7.8. A breathable membrane passes water vapour while blocking liquid, which is the difference between a protector that works and a sheet of plastic with a nicer face.

Buy it if

You want waterproofing that does not make the bed hotter.

Do not buy it if

You need a six-sided allergy encasement.

Origin Extend Mattress Protector: Best depth fit

Budget to mid · 7.6 / 10

Scores 7.6. Depth is what decides whether a protector stays on: modern hybrids run 28 to 35 centimetres while most protectors are cut for around 25, and one that pings off a corner ends up in a drawer.

Buy it if

You have a deep mattress, which is most modern hybrids.

Do not buy it if

Your mattress is shallow.

Panda Bamboo Mattress Protector: Best feel

Mid range · 7.5 / 10

Scores 7.5. A soft cover face over the membrane resolves most complaints about noise and feel, which is the usual reason a protector gets taken off and not put back.

Buy it if

You dislike the slight crunch some waterproof protectors have.

Do not buy it if

You want the cheapest effective option.

Mlily Cool Protect Mattress Protector: Best if you sleep hot

Budget to mid · 7.5 / 10

Scores 7.5. If you bought a mattress for its spring airflow, the protector is the most likely thing to cancel it out, and this category takes that seriously.

Buy it if

You bought a hybrid for airflow and do not want to undo it.

Do not buy it if

You want maximum waterproofing at any cost to breathability.

The routine that actually keeps a mattress clean

What to do and how often
TaskHow oftenWhy
Wash bedding at 60 degreesWeeklyDust mites survive a 40 degree wash
Wash the protectorEvery few weeksIt is doing the work; wash it, not the mattress
Vacuum the mattress surfaceEvery few monthsRemoves skin and dust before it works in
Air it uncoveredEvery few monthsParticularly on a solid platform base, where moisture collects underneath
Rotate head to footEvery two to three monthsSpreads wear. Turn as well if double-sided.

Note what is not on that list: wet cleaning. The protector is the thing you wash, and the mattress is the thing you keep dry.

Dealing with a spill, in order

Blot, do not rub. Press a dry towel down hard to lift as much liquid as possible. Rubbing pushes it deeper and spreads the stain outward.

Use as little liquid as you can. A lightly damp cloth, not a soaked one, and never pour anything onto a mattress.

Work from the outside inward, so you do not spread the mark.

Dry it properly and completely. This is the step that matters most. Open a window, use a fan across the surface, and leave the mattress uncovered and unmade for as long as it takes. Do not put bedding back on a damp mattress.

For biological stains, an enzyme-based cleaner applied sparingly works better than a general cleaner, because it breaks down protein rather than diluting it. Test on a hidden area first.

What not to put on a mattress

A steam cleaner. It drives moisture deep into the fillings and the spring unit, and it is a common way to cause mould and rust. Manufacturers frequently prohibit it, and doing it can void your guarantee.

A carpet washer or wet vacuum. Same problem, more water.

Bleach or strong solvents. They damage foam and fabric and can discolour permanently.

Large amounts of bicarbonate of soda left for hours. It absorbs moisture and then you have to remove all of it, and what stays in the fabric attracts more moisture later. A light sprinkle, an hour, and a thorough vacuum is the sensible version.

Anything at all, if the mattress is under guarantee and visibly damaged. Photograph it and speak to the retailer first, because your statutory rights sit with whoever sold it to you.

Smells, mould and when to stop

A mattress that smells musty rather than of a specific spill usually has a moisture problem rather than a dirt problem.

Air it thoroughly, ventilate the room daily, check whether it sits on a solid platform base that blocks airflow underneath, and lower the humidity if you can. Mites and mould both need humidity.

Visible mould inside or on a mattress is the end of it. You cannot reliably remove mould from within fillings, and a mattress at that stage should be replaced rather than treated.

For disposal, a council bulky waste collection typically costs 20 to 40 pounds and usually requires getting it to the kerb yourself. Some retailers take the old one away with a delivery, and Panda includes free recycling on mattress orders, any brand.

What not to do

Steam clean a mattress. It drives moisture into the fillings and frequently voids the guarantee.

Soak a stain. Blot, use as little liquid as possible, and dry completely.

Put bedding back on a damp mattress.

Use bleach or strong solvents.

Skip the protector. A stain voids most guarantees absolutely, which makes prevention the only cleaning strategy that works.

Also considered, and why they are not here

A roundup is only as useful as what it leaves out, so here is what was assessed and rejected for this list.

Considered and not recommended here
ProductWhy it is not on the list
Emma ProtectorScores 7.6 and is a sound choice. Check the depth against your mattress, because that is where protectors most often fail in practice.
Nectar ProtectorScores 7.6. Worth buying alongside a Nectar mattress specifically, because a stain ends a 365 night trial as well as the guarantee.
Simba ProtectorScores 7.5. Covered by Simba's community hero scheme, which runs up to 31 per cent and applies to bedding.
Eve ProtectorScores 7.5. Competent, and worth noting that a protector's fate does not depend on the brand's trading history the way a mattress guarantee does.

How this list is made, and who made it

Independence

No brand pays to appear on this site and no placement is sold. Some links earn a commission if you buy, which never changes a score, an order or a verdict. Several of the lowest scores here are on products that carry commission, and several recommendations carry none.

Who writes this. Kyle Klinkradt has worked in the mattress and bedding industry for over ten years across retail, distribution and brand partnerships, and has handled, sold or assessed products from every major UK bed-in-a-box brand. Every review on this site is written by one person, so the scores mean the same thing from page to page.

What the assessment is. Construction specifications against what they physically do: spring height and where in the mattress it sits, spring count for the size, gauge, whether the base is sprung or foam, foam density where it is published, comfort layer depth and material. Then the commercial terms that decide what you are actually buying: trial against returns policy, guarantee length against the company's UK trading history at Companies House, and the regulatory record.

What it is not. This is not a laboratory. I do not publish pressure-mapping data or claim to have slept eight years on every mattress here, because nobody has and pages that imply otherwise are not telling you the truth. Where a judgement rests on construction rather than long-term use, the review says so.

What gets a product removed. Leaving the UK market, a specification change that makes the review inaccurate, or a corrected fact. Brands that have withdrawn are kept on the site with the score removed rather than quietly deleted, because people still search for them.

See editorial independence, corrections and the author page.

How these were chosen

Every product here has its own review on this site with a score out of 10, and the score is a judgement rather than an average. Nothing appears in a list because it pays more.

A score is against the market, not against its own range. The cheapest mattress in a lineup is usually priced to make the model above it look reasonable, and the flagship of a budget range has risen into a bracket where better brands compete. Both are judged against what else you could buy for the money.

Everything listed can actually be bought in the UK. That is not a given: Casper withdrew in July 2020 and Leesa no longer sells here, and both still appear in current British roundups with affiliate links attached.

I do not pad the list. Where only three or four products genuinely qualify, there are three or four. A list of seven when the category contains four good ones is a list with three bad recommendations in it.

Prices move constantly. Judge the cash price on the day rather than any percentage beside it. See every review on this site or where the real savings are.

Questions people ask

How do I clean a mattress?

Surface only, with as little liquid as possible. Blot rather than rub, work from the outside inward, and dry it completely with a window open and a fan across the surface before putting bedding back.

Can I steam clean a mattress?

No. Steam drives moisture deep into the fillings and the spring unit, which causes mould and rust. Manufacturers frequently prohibit it and doing it can void your guarantee.

Does bicarbonate of soda clean a mattress?

A light sprinkle for an hour followed by thorough vacuuming is reasonable for odour. Large amounts left for hours absorb moisture and are hard to remove completely, and what stays in the fabric attracts more moisture later.

What should I do about a musty smell in a mattress?

Treat it as a moisture problem rather than a dirt problem: air it thoroughly, ventilate the room daily, and check whether it sits on a solid base that blocks airflow underneath. Visible mould inside a mattress means replacing it.
