How to Remove Pee Stains (and Smell!) From a Mattress

6 Materials
60 Minutes

If you have a young child or a pet in the house, chances are you at some point will have to deal with pee stains on a mattress even if you use a mattress protector. Accidents happen. So be grateful that I have the magic formula for removing those pee stains!
To remove pee stains from your mattress you will need hydrogen peroxide, baking soda, dish soap, lavender essential oil (if you like) and a funnel and a spray bottle.
You'll mix the hydrogen peroxide, baking soda, liquid hand dish washing soap, and lavender essential oil all together in the spray bottle. Spin it all together in the bottle a little bit but don't shake it.

Take that spray bottle and spray it all over those pee stained mattresses!
I had two mattresses that were stained (twins) and here are the before.
The other mattress before stain removal.
And after!!
After!! There was still a very slight yellow coloring, but so much better and the smell was gone!
To finish up, let the mattress dry (about one hour) and then vacuum them to get up the gritty baking soda off.

    I’ve been doing this for years and it works. 2 cups hydrogen peroxide, 2 Tbs baking soda and scant tsp Dawn (Dawn is best).

    Why not purchase a 6 pack of washable mattress protectors that pop in the wash. Nursing homes use them, can buy online, not expensive and last forever. They are 3' square soft pads. Used for a relative for years.

      This isn't just for mattresses. I have used it on my furniture - lots of pups - and it works perfectly. If you have this problem, you will know that most all commercial products claiming to fix the problem DO NOT work.

      my little fur boy is now an old man with a sick tum. thank goodness for my spray bottle of peroxide. the color, smell and germs are completely removed fr my rugs. protect hardwood fr peroxide by putting plastic under. beware that peroxide can bleach some fibers
