How to clean urine stains from a bed mattress

If you have pets or kids, you are likely to have urine stains on a mattress from time to time. Accidents happen, and removing urine stains from your mattress is not difficult. The key is to act fast, if possible, and remove the urine completely so no stain or lingering odour remain. Expensive commercial products exist to help with this job, but you can use supplies around the home to thoroughly clean urine stains from your mattress, while sparing the expense.

Place a thick layer of paper towels over the site of the urine stain and apply pressure to soak up as much of the urine as possible. Toss out urine-soaked paper towels and lay fresh paper towels on the urine to continue soaking up the urine until there's no further transfer.

Cover the site of the urine stain on your mattress with baking soda. Allow the baking soda to remain on the mattress until it turns yellow, then scoop it up and replace it with fresh baking soda. Keep replacing the baking soda on your mattress until it stays white and doesn't wick up anymore urine. Allow the last pile of baking soda to remain on the mattress overnight to ensure removal of urine stains and odour.

Vacuum the baking soda off your mattress.

Measure 2/3 cup of water and 1/3 cup of white vinegar and pour both into a spray bottle. Shake the mixture together, then spray the urine stain liberally. Work the vinegar spray into the urine stain, using a clean cloth.

Sponge at the site of the urine stain on your mattress with a clean sponge dampened with cool water. Air-dry your mattress, leaving a window open, if possible, to aid the drying process and fill the room with fresh air.


Use a mattress cover to protect your mattress from stains. The mattress cover can be removed and washed, while keeping your mattress clean and fresh.


Avoid wiping or scrubbing at stains on your mattress. Blot, dab or apply pressure to the stain as rubbing and scrubbing will spread the stain.
