Can Urine Ruin Memory Foam?


Yes, urine can potentially ruin a memory foam mattress, especially if you don’t act quickly and clean the area.

The moisture can seep into the layers of foams and negatively affect the performance of the layers inside the mattress.

Besides this, urine can also cause an odor, which is definitely something that doesn’t make up for a good night’s sleep.

Additionally, most mattress companies will not honor the warranty for a mattress if there is a stain that was caused by your side and not theirs, so the only way to get rid of this inconvenience is to clean the mattress yourself.

Can You Clean Urine From a Memory Foam Mattress?

Yes, you can clean urine from a memory foam mattress by either using adequate detergents or simply turning to a few natural ingredients from your kitchen cabinet to save the day.

However, if you don’t feel comfortable trying these for yourself, it is always a good idea to contact the manufacturer and ask for advice on how to remove the particular stain.

How To Clean Wet Urine From a Memory Foam Mattress?

The deed was just done and luckily you noticed the gift from your child or your pet in time, so the only thing to do now is to act quickly.

If the mattress is still wet, you have a pretty good chance at making it appear as if nothing ever happened, so here are the few things you need to grab:

  • Paper towels
  • Spray bottle
  • Vinegar
  • Laundry detergent
  • Baking soda

This cleaning method will also take care of the unwanted odor, so here are all the steps you need to do:

Get rid of the wetness

First things first, you want to get rid of as much wetness as you can, therefore, you need to grab some paper towels, kitchen rolls, or what have you, and proceed to blot the stain.

It’s important that you don’t try to scrub the moisture away as this can possibly embed the urine even deeper into your mattress and will eventually result in odor over some time.

Spray the area with vinegar

The worst part is over once you’ve blotted most of the moisture away so here’s what to do next:

Get a spray bottle and dilute white vinegar with water in a 50/50 mixture. You don’t have to fill up the entire bottle as you will not need to use all of it, however, make sure to have an adequate mixture.

Spray the area with vinegar a few times and blot away the excess wetness before spraying some more and leaving it to soak anywhere from ten to thirty minutes to help neutralize the smell of urine.

Another useful tip is to open a window and run a fan while doing this as vinegar doesn’t really have a pleasant scent on its own.

Blot the extra vinegar away

You can now go back to the mattress and continue blotting the extra vinegar away.

Blot as much as you can to get rid of extra moisture, however, don’t scrub as this can potentially damage your mattress.

Spray the area with laundry detergent

Fill the spray bottle with laundry detergent mixed with water and shake it well.

You can spray this mixture on the stain and let it soak for about ten to twenty minutes this time.

Blot the extra detergent away

Repeat the process as before and make sure to blot the extra moisture away as much as you can. Again, avoid scrubbing because you don’t want to push detergent into the deeper layers of the memory foam.

Use essential oils to get rid of the odor

Before moving on to the final step, you can spray a few drops of lavender, peppermint, or lemongrass essential oils diluted in water and let it soak for ten to twenty minutes.

Essential oils are potent fragrant components that will help get rid of any remaining odor that’s left lingering.

Make sure to blot the moisture before continuing.

Sprinkle baking soda on the damp area

The last ingredient of the process is good old baking soda and you can sprinkle it on the wet spot left on the mattress.

Make sure to completely cover the stain in baking soda and let it sit anywhere from 8 to as long as 24 hours to let it completely soak up any leftover moisture.

Vacuum the baking soda remains

After you’ve allowed the baking soda to soak up the moisture from the memory foam mattress, you can use a vacuum to clean up the dried baking soda and make sure to carefully inspect the area.

If there is still staining or odor left behind, you can repeat this process until the mattress is all clean and odorless.

How To Clean Dry Urine From a Memory Foam Mattress?


Depending on the weather and the room temperature, it can take as little as 15-18 hours for urine to fully dry on a mattress.

Therefore, if you’ve missed the small accident only to discover the damage once it’s already dry, you will need to have a heavier cleaning solution to do the heavy lifting for you.

Here are the things you need to create a mixture that will clean dry pee from a memory foam mattress:

  • 8 oz Hydrogen peroxide
  • 3 tbs Baking soda
  • 1 tbs Liquid detergent

All you have to do once you mix these three ingredients is to spray a generous coating over visible stains and make sure you cover everything evenly.

Let the mixture sit until dry and while this is happening you should see a layer of baking soda residue form on the area.

Vacuum off the residue once dry and you are good to go.

Additionally, if the odor is still present after doing this, you can try the same option with essential oil that we mention above.

Simply mix a few drops of lavender, peppermint, or lemongrass essential oils in water and spray over the area. Leave it to sit for about ten to twenty minutes and blot before leaving it to dry.

Clean Urine Stains From Your Mattress With an Enzyme Cleaner

This is another effective way to permanently clean urine stains from your memory foam mattress and this solution is an absolute must, especially if you have pets.

Enzymatic cleaners are products that use enzymes in their formulas and these enzymes help break down stains.

Enzymes are macromolecular biological catalysts that speed up chemical reactions; this usually occurs in the body, but in the case of enzymatic cleaners, the process is used for a different purpose.

In a nutshell, different enzymes break down different types of stains.

Lipases work on fats or oil-based stains, amylases tackle carbohydrates and starches, and proteases break down protein-based stains including blood, urine, food, feces, wine, and other beverages.

Any type of urine from mammals, whether it is human or pet urine, contains uric acid crystals, which can effectively be removed by using enzymatic cleaners due to their ability to bind with and destroy the uric acid.

How To Protect Your Mattress From Urine?

The best way to ensure that your memory foam mattress is protected is to invest in some mattress protectors that will give you a solid defense.
