Memory foam mattresses are amazing! They are comfortable and light. However, the problem with memory foam mattresses is that they very easily soak all kinds of nasty substances. This means that during hot summer months your memory foam mattress is particularly susceptible to sweat stains.

One option is using a natural latex topper to prevent it, but if you have recently discovered a sweat, urine or any other mattress stain, we are here to show you how you can clean the mess up, and how you can make your memory foam mattress flawless.

“It may seem challenging, but removing sweat stains from a memory foam mattress can be handled effectively at home without causing harm to the material. The key is to use mild detergents and avoid soaking the material. Always remember to dry it thoroughly post-cleaning to prevent mould or mildew. Trust the process; patience and care are your allies when it comes to mattress cleaning.”

Vacuum the Mattress

Before you start removing the stains, you need to take off the mattress cover. After you have done that, you should use a vacuum cleaner to suck all the debris like dust mites, dead skin cells, or dirt that may have accumulated on it. If you have a steam cleaner, that can help out a lot. The steam will also clean and disinfect your mattress.

Once you are finished vacuuming the entire surface of the memory foam mattress it’s time to start the process of removing the stains. Good news, it’s easier than you think and you can do it in no time.

Gather All of the Necessary Materials

To clean your memory foam mattress, you need to gather all of the necessary materials for the cleaning solution. The solution will consist of:

  • Baking Soda
  • hydrogen peroxide
  • large spray bottle
  • damp cloth
  • dry towel/paper towel
  • Liquid dish soap/mild detergent

After you have assembled all of these materials it’s time to start cleaning the sweat stains from the memory foam mattress.

Create the Solution

The first thing you’re going to want to do is to take the spray bottle that you’ve prepared. Into that spray bottle, you are going to add three tablespoons of baking soda, along with 2 to 3 drops of liquid dish soap, and a couple of ounces of warm or hot water.

After you have done that, you need to shake the mixture until it is completely combined. When you are done mixing it, now it’s time to add 8 ounces of hydrogen peroxide.

Hydrogen peroxide will help immensely in the process of removing stains, no matter if they are, sweat stains, urine stains, blood stains. Hydrogen peroxide will help make your memory foam mattress clean from even the tough stains.

Again shake the spray bottle until you are sure that all of the ingredients are mixed well. After you have done that, you need to lightly spray the mixture onto the stained area. Let it sit there for 5-10 minutes for the hydrogen peroxide cleaning solution to soak into the tough stains.

If you soak the mattress stains a bit too much, you can use paper towels to blot the excess liquid. After you’ve let it sit there for 10 minutes, blot the sweat stain with a clean cloth to remove any excess moisture.

Tend to Any Bad Smells

You may notice that after you remove sweat stains from the matter, you still find that it smells bad. That is because if you want your mattress to smell fresh, you need to go the extra mile!

First, you should take another large spray bottle and mix a bit of distilled white vinegar with hot water into it. If you find the smell too pungent, you can add a bit of essential oil to the mix. After you mix the solution, spray the whole surface.

After you’ve let it dry for a while, you should sprinkle baking soda over the whole thing. Let it sit for a few minutes, and then vacuum it up and move on to the next step.

Use an Appropriate Mattress Protector

Prevention always beats a cure. Why burden yourself with how to clean a memory foam mattress from sweat stains, when you can prevent them from ever forming.

You should invest in a waterproof mattress protector. A quality mattress cover will save your entire mattress from sweat stains, dust mites, yellow stains, and blood stains.

This way you will be able to have a good night’s sleep, without worrying about anything.

7 thoughts on “How To Remove Sweat Stains From Memory Foam Mattress”

  1. As a father with more than a fair share of mattress incidents, I’ve found vinegar an effective weapon against most stubborn mattress stains. It’s always a matter of acting quickly though, the quicker you can address the stain, the better. Just remember to go easy on the water during cleanup, memory foam doesn’t do well with excess moisture!

  2. Interesting point, Kelson, but as a chemist, I feel the need to mention that the acetic nature of vinegar can potentially deteriorate memory foam’s cellular structure over time; perhaps a milder, pH-neutral cleaner would be better for longevity.

  3. I agree with you Zygmunt regarding vinegar’s potential harm to memory foam’s structure. As an industry insider, I have observed that using enzyme-based mattress cleaning sprays can effectively remove sweat stains without damaging the material.

  4. Just last week I dealt with a stubborn stain on our memory foam mattress – my twins spilled their grape juice all over it! I tried lots of methods, but what really worked was a mixture of baking soda, mild detergent, and water – applied gently on the stained area with a soft sponge. Save the harsher solutions for more durable materials only, I’d say.

  5. True, Wraxall! Harsh chemical solutions can ruin the integrity of the memory foam. In case of strong stains, I’ve found vinegar mixed with lukewarm water (1:2 ratio), lightly spritzed on the area, works wonders without damaging the material.

  6. I have to chime in here Norville, the vinegar solution is definitely superior to harsh chemicals when it comes to treating stains on memory foam, not just due to the preservation of the material’s integrity but also because it’s less hazardous to our health. However, dilution ratio varies based on the severity of the stain – stronger stains might require a 1:1 vinegar-water solution.

  7. I must contest your claim, Esbjornson. While vinegar can certainly be a good choice for most stains, its acidic properties might inadvertently harm the memory foam structure over time, reducing its comfort and longevity.
