How to Clean Urine Stains From Mattresses

If you take care of a child struggling with bed wetting, an elderly parent affected by incontinence or a rambunctious pet still being house-trained, it's likely you'll be faced with the challenge of cleaning urine off a mattress. A soiled mattress requires immediate attention. The sooner that it is cleaned, the less likely the odor is to set. A mattress allowed to absorb liquid also runs the risk of becoming moldy. Prompt and proper cleaning is the key to keeping your mattress a healthy place to sleep.

Blot up the urine with a dry towel. Refrain from rubbing, as this will only spread the stain.

Sprinkle some baking soda on the stain. This will absorb moisture and help to stop the odor.

Spray some hydrogen peroxide on the stained area and allow it to sit for a few minutes. Blot up any remaining moisture.

Sprinkle the entire mattress with baking soda and let the mattress dry overnight.

Vacuum the baking soda from the mattress.


Take a preventive measure by using a cover for your mattress. Vinyl zip covers can be purchased, but an affordable alternative is to use garbage bags. An alternative to hydrogen peroxide is a mixture of one part white vinegar to one part warm water. There are products on the market that can be used specifically for urine stains caused by pets. An effective method for making sure a mattress is dry is to allow it to dry in the sun.
