A routine mattress cleaning takes care of stray hair, dirt, lint, and other debris. These things can get ground into your mattress and permanently damage the foam if they’re neglected. Whenever you change your sheets, use a hand-held vacuum or a standing vacuum with a brush attachment to sweep over the surface and sides of your mattress.


Tip: Some memory foam mattresses have small crevices in their covers. Make sure you reach into these nooks and crannies with your vacuum while you’re cleaning.


Clean Stains With a Homemade Memory Foam Cleaning Solution

If your mattress ever gets stained, spot-clean it with a mild fabric solution. Fill a spray bottle with a 1/2 cup of fabric cleaner and 1 cup of water. Do not use bleach. Give the bottle a quick shake to ensure that the cleaner is completely mixed, then spray the stain until you cover it entirely. Be sure you don’t spray more solution than you need. Memory foam is essentially a large sponge, so it can take a very long time to dry if it gets too wet.


Next, take a rag and gently scrub the stain with small, circular motions. Don’t scrub too hard or you may press your cleaning solution further into the foam than you need to.


After the stain is removed, wipe the spot with a wet rag to remove any excess solution and let it dry completely before putting your sheets back on the bed.


Tip: The faster you clean a stain, the easier it is to remove. Whenever possible, don’t let stains in your memory foam dry before you get to them.


For Tough Stains, Use a Vinegar Solution

If you’re having a lot of difficulty with an exceptionally stubborn stain, you can try cleaning it with something a little stronger than the fabric solution above. Fill a spray bottle with 1/4 cup white vinegar and 3/4 cup water. Shake well, then spray the solution on the stain. Gently scrub the stain and wipe away any excess solution with a wet rag. Let the spot dry before putting the sheets back on.


Tip: Some people recommend using a hydrogen peroxide solution on tough stains. This can work, but it is risky because hydrogen peroxide can damage or discolor fabrics and memory foam.


Clean Urine Out of Your Memory Foam Mattress With White Vinegar and Baking Soda

If your potty-training toddler or puppy has a bedwetting problem, those stains can be very difficult to clean because memory foam is so absorbent. Act fast to prevent lasting damage.


First, use paper towels to absorb as much urine as possible. Discard the towels as soon as they are saturated. Repeat until you have absorbed as much of the liquid as you can.


Next, cover the affected area with white vinegar from a spray bottle, then use paper towels to absorb the vinegar.


Last, cover the spot with baking soda and let it stand. After 8-10 hours, vacuum up the baking soda. Make sure the spot is completely dry before you put your sheets back on.


Tip: If you successfully remove the stain but your mattress still smells bad, try putting it outside in the sun for a few hours. The sun’s radiation can help to deodorize the mattress. Lay the mattress on a tarp to avoid getting it dirty. For more tips, check out our guide on How to Clean Urine From a Memory Foam Mattress.


Quickly Dry Your Memory Foam Mattress With a Fan or Hair Dryer

Whenever you get memory foam wet, you want to dry it quickly. Use a small fan or a hair dryer on a low-heat setting to dry the memory foam mattress as much as possible, then leave the it in a well-ventilated area to dry. It may take one or two days for the memory foam to fully dry. You can use the hair dryer or fan every few hours to help the drying process.


Tip: Don’t use the high-heat setting on your hair dryer to dry memory foam. Additionally, don’t use the hair dryer for more than a few minutes at a time. Excessive heat can cause memory foam to pucker.


How to Keep Your Memory Foam Mattress Clean

The first step in memory foam care is prevention. You should always cover memory foam mattresses used by young children or pets with a waterproof mattress protector. A waterproof cover can also prevent stains from those spilled snacks and drinks that somehow get snuck into bed.

Sometimes, memory foam simply can’t be saved. Memory foam’s absorbent qualities can make it almost impossible to remove exceptionally large, smelly, or dark stains. If the methods above don’t work for your situation, it may be time to consider replacing your memory foam mattress instead of trying to clean it.
