How to clean urine from a memory foam mattress?


Cleaning urine from a memory foam mattress can be a challenging task, but with the right approach and materials, it is possible to restore your mattress to its original condition. This article will provide you with a step-by-step guide on how to effectively clean urine from a memory foam mattress, ensuring that it is fresh, clean, and odor-free.

Materials Needed

Before you begin the cleaning process, gather the following materials:

– Baking soda
– White vinegar
– Hydrogen peroxide
– Mild detergent or dish soap
– Spray bottle
– Clean towels
– Vacuum cleaner with upholstery attachment
– Enzyme-based cleaner (optional)

Step-by-Step Cleaning Process

Step 1: Act quickly: It is essential to address the urine stain as soon as possible to prevent it from seeping deeper into the mattress. The longer the urine sits, the more challenging it will be to remove.

Step 2: Blot the urine: Start by blotting the urine with clean towels or paper towels. Avoid rubbing or scrubbing, as this can spread the stain and push the urine deeper into the mattress.

Step 3: Vacuum the mattress: Use a vacuum cleaner with an upholstery attachment to remove any loose debris and absorb moisture from the mattress. This will help prepare the mattress for the cleaning process.

Step 4: Create a cleaning solution: In a spray bottle, mix equal parts white vinegar and water. Vinegar is known for its natural cleaning properties and can help neutralize odors.

Step 5: Spray the affected area: Generously spray the urine stain with the vinegar and water solution. Make sure to cover the entire affected area.

Step 6: Blot with clean towels: Once again, blot the area with clean towels to absorb the vinegar solution and urine. Repeat this process until the towels come out relatively dry.

Step 7: Apply a detergent solution: In a separate spray bottle, mix a small amount of mild detergent or dish soap with water. Spray this solution onto the urine stain and gently scrub the area with a clean cloth or sponge.

Step 8: Rinse with clean water: After scrubbing, rinse the area with clean water to remove any soap residue. Blot the excess moisture with clean towels.

Step 9: Remove odor with baking soda: Sprinkle a generous amount of baking soda over the affected area. Baking soda is excellent for absorbing odors. Leave it on the mattress for several hours or overnight.

Step 10: Vacuum the baking soda: Use a vacuum cleaner to thoroughly remove the baking soda from the mattress. Ensure that all traces of baking soda are eliminated.

Step 11: Optional: Use an enzyme-based cleaner: If the urine odor persists, you may consider using an enzyme-based cleaner specifically designed for removing urine stains and odors. Follow the instructions provided by the manufacturer.


Cleaning urine from a memory foam mattress requires prompt action and the right materials. By following the step-by-step guide outlined in this article, you can effectively remove urine stains and odors, restoring your mattress to its original condition. Remember to act quickly, blot the urine, and use appropriate cleaning solutions to ensure the best results.
