How to clean urine from a memory foam mattress

Urine is one of the most basic bodily functions, and people are constantly leaving it behind on furniture, mattresses, and other surfaces. Urine can contain bacteria, which can cause odor and mold growth. In some cases, urine may also cause allergic reactions in people who are sensitive to certain chemicals found in urine. How can you clean urine from a memory foam mattress?

Cleaning urine from a memory foam mattress is not as difficult as it seems. There are a few simple steps that you can follow to get the job done correctly. First, you will need to gather all of the necessary materials. You will need water, soap, a vacuum cleaner with a hose attachment, and a microfiber towel. Next, you will want to moisten the towel with water and scrub the mattress surface where the urine has been deposited. After cleaning the area, you will need to dry it off with a towel. Finally, you can vacuum the surface clean.

Accidents involving urine on a memory foam mattress can be distressing, but with the right approach, you can tackle the problem effectively. Acting swiftly is crucial to prevent the urine from seeping deeper into the mattress and causing persistent stains and odors. By following the steps outlined below, you can successfully clean urine from a memory foam mattress and restore its freshness.

Act fast to prevent stains

Fresh urine is considerably easier to clean than dried urine, so it’s important to take action as soon as possible. The longer the urine remains on the mattress, the more challenging it becomes to eliminate the stains and odor. Therefore, don’t delay the cleaning process.

Remove excess moisture

Before applying any cleaning solution, start by gently pressing rags or paper towels on top of the affected area. This will help absorb and remove excess moisture from the mattress. Avoid rubbing or scrubbing, as this can push the urine deeper into the foam.

Try a DIY cleaner

For an effective and natural solution, consider using a DIY cleaner made from white vinegar and water. Mix equal parts of white vinegar and water in a spray bottle. Saturate the area on your mattress with the solution and allow it to penetrate for a few minutes. Then, follow up with a layer of baking soda.

The combination of white vinegar and baking soda helps neutralize odor and break down urine stains. It is particularly useful for removing cat and dog urine from a mattress. Alternatively, you can lightly spritz the affected area with the vinegar and water mixture, blotting any remaining moisture and odor.

Cover the area with baking soda

Once you have applied the vinegar solution, cover the entire affected area with a generous layer of baking soda. Baking soda is a natural deodorizer that helps absorb moisture and eliminate odors.

Let the solution sit

Allow the vinegar and baking soda solution to sit on the mattress for several hours or, ideally, overnight. This gives the cleaning agents enough time to work their magic and break down the urine stains and odors.

Vacuum the baking soda

After the solution has had enough time to penetrate the mattress, use a vacuum cleaner with a brush attachment to remove the baking soda. Ensure that you thoroughly vacuum the entire surface of the mattress, paying extra attention to the previously affected area.

Repeat the process if needed

Memory foam mattresses tend to absorb liquid more quickly than traditional mattresses, so it may be necessary to repeat the cleaning process a few times for optimal results. If the urine stains and odor persist after the first attempt, don’t get discouraged. Simply repeat the steps until the mattress is clean and fresh.


Cleaning urine from a memory foam mattress may seem like a daunting task, but by acting promptly and following the right steps, you can effectively remove stains and eliminate odors. Remember to act fast, remove excess moisture, utilize a DIY cleaner with white vinegar and baking soda, and let the solution sit before vacuuming. With patience and persistence, your memory foam mattress will be restored to its pristine condition.
