Memory foam mattresses are a favorite among many, and for good reason. They’re known for being incredibly comfortable and providing endless amounts of support to sleepers by contouring to their bodies and relieving pressure. But do you know how to clean memory foam?

If you’re in the market for one, there are plenty of resources available to help you choose the best ones.

With that being said, the special material that memory foam is made from needs to be properly cared for and kept clean in order to prevent deterioration, especially to reduce the chance of mites getting into them and calling your mattress their own home.

In fact, 40.5% foam mattresses without covers end up being infested, and 26.3% of foam mattresses without covers get dust mites in them too.

This is why keeping a memory foam mattress clean is so important! We’ve compiled some handy tips to keep your memory foam mattress in pristine condition.

Basic Cleaning

The simplest way to clean your mattress is with a vacuum, and it’s one of the quickest and easiest, too. This is a great method for the general maintenance of your mattress.

Daily vacuuming can actually reduce dust mites, endotoxins, and fungi growth in a mattress by between 70-85%!

Simply remove all bedding, including the mattress cover, and gently run the vacuum over your memory foam. The upholstery attachment is the best option for this job. Make sure to turn over each side of the foam layers in your mattress and clean it thoroughly.

It may be a good idea to give your mattress cover or topper a wash at the same time – just read the washing instructions you’re good to go.

Stain Removal

A common error that memory foam mattress owners do is using commercial cleaners – often containing bleach or other harsh chemicals – to get rid of any stains on their beds. But the ingredients contained within those products can often do more harm than good to your memory foam.

The best way to safely and properly get stains off of memory foam is with a mild detergent, diluted with water until the mixture is mostly bubbles.

You can use dishwashing liquid for this purpose. To rub the stain off, use a clean sponge and rub in a circular motion, working your way from the outer ring of the stain inwards. Be careful – do not use any actual solution, bubbles only!

Don’t have a detergent you can use? You can replace the solution with a mixture of vinegar and water and use it in a spray bottle.

Vinegar works wonders for removing stains, and it can also get rid of any nasty smells that came with the mishap. Work quickly by giving the stained area a light spray and then scrubbing at it with cloth or a clean rag.

Exercise restraint in your cleaning process. Memory foam does not do well with copious amounts of water, so the less you use the better.

Be gentle in your efforts, as being too rough could end up getting the stains more embedded in the foam, or you could just end up getting too much liquid on the mattress and winding up with a bad case of mildew.

If needed, you can also purchase an enzymatic cleaner, but be sure to follow the directions on the bottle. In a pinch, you can also use baking soda by directly sprinkling soda on the stain, leaving it overnight, and cleaning it with a vacuum in the morning.

Cleaning Spills

If you’ve just spilled a lot of liquid onto your mattress, you’ll have to get it dry as soon as possible.

If the mattress is not too difficult to move and it is sunny out, bring it out to dry under the sun, then address stains with the methods we’ve covered in the Stain Removal section.

If you can’t move the mattress outside, use clean and absorbent towels or rags to dab at the spill. Gently press down on the spot and rotate the cloth around so you always have a dry area to use. Do not try to roughly scrub the spill off; this can just cause the stain to set.

If possible, place an electric fan in front of the mattress and set it on as high as you can in the direction of the spill. Leave the mattress to dry for a few hours and be sure not to cover it with bedding or toppers until it is entirely dry.

If the mattress still feels damp after all this effort, use a hairdryer on a cool setting to dry up any remaining wetness. Do not use a high or hot setting as this can damage the foam badly.

Odor Removal

The simplest way to kill extra odors is to bring your mattress out on a sunny day and allow the heat and wind to kill bacteria and give the mattress a good deodorizing treatment.

If you cannot bring the mattress out or if there are more stubborn smells, get yourself a lot of baking soda and sprinkle a very thin layer over the entirety of the mattress’ surface, then leave on overnight or throughout the whole day. Vacuum up the powder when it’s done.

You can also use a citrus cleaner, but this takes a little extra effort to make. With that being said, a homemade citrus cleaner can be useful to have around the house.

Place orange or lemon peels in an airtight container, pour white vinegar into the container, close it, and leave it be for about two weeks. Remove the peels and transfer the remaining liquid into a spray bottle.

You can use this solution to very lightly spray your memory foam mattress to give it a fresh smell and remove odors, but remember not to use too much of it! Allow the mattress to dry completely before putting on bedding.
