How to get pee out of foam mattress?


Accidents happen, and sometimes that includes accidents involving our mattresses. If you find yourself dealing with a urine stain on your foam mattress, it’s essential to act quickly to prevent any lingering odor or damage. In this article, we will explore effective methods for removing pee stains from a foam mattress, ensuring that your mattress stays clean and fresh.

Materials Needed

Before we dive into the cleaning process, let’s gather the necessary materials:

1. Baking soda
2. White vinegar
3. Dish soap
4. Hydrogen peroxide
5. Clean towels or paper towels
6. Spray bottle
7. Vacuum cleaner

Step-by-Step Cleaning Process

Step 1: Act Fast
The sooner you address the urine stain, the better. Start by removing any excess urine using clean towels or paper towels. Blot the area gently, avoiding rubbing, as this can push the urine deeper into the foam.

Step 2: Prepare the Cleaning Solution
In a spray bottle, mix equal parts white vinegar and water. Vinegar is a natural disinfectant and helps eliminate odors. Spray the solution onto the stained area, ensuring it is fully saturated.

Step 3: Blot with Towels
Using clean towels or paper towels, blot the stained area to absorb the vinegar solution. Repeat this process until the towels come away relatively dry.

Step 4: Apply Baking Soda
Sprinkle a generous amount of baking soda over the stained area. Baking soda is excellent for absorbing odors. Leave the baking soda on the mattress for a few hours or overnight to allow it to work its magic.

Step 5: Vacuum the Baking Soda
Using a vacuum cleaner with an upholstery attachment, thoroughly vacuum the baking soda from the mattress. This will help remove any remaining urine residue and deodorize the mattress.

Step 6: Treat Stubborn Stains
If the stain persists, you can create a cleaning solution by mixing one tablespoon of dish soap with two cups of warm water. Dampen a clean cloth with the solution and gently blot the stained area. Avoid using excessive water, as it can damage the foam.

Step 7: Rinse and Dry
After treating the stain, dampen a clean cloth with water and blot the area to remove any soap residue. Then, use a dry towel to absorb excess moisture from the mattress. Finally, allow the mattress to air dry completely before putting any bedding back on.


Accidents happen, but with the right approach, you can effectively remove pee stains from a foam mattress. Acting quickly, using the appropriate cleaning materials, and following the step-by-step process outlined above will help ensure that your mattress remains clean, fresh, and odor-free.

Remember, prevention is key. Consider using a mattress protector to safeguard your mattress from future accidents. Regularly cleaning and maintaining your mattress will also help extend its lifespan and keep it in optimal condition.
