How to Get Pee Out of a Mattress In 5 Simple Steps

Ever wondered how to get pee out of a mattress? We did too. Since we’re into having a quality mattress we wondered. What if you have a great mattress but now you have pee stains on it? You can try and clean it yourself but it’s not easy. We’ve tried! This is a great method using inexpensive items that you probably have around the house already. When we learned about it, we had to test it out. Does it really work??

How to Get Pee Out of a Mattress

You can get pee on a mattress from a child who wets the bed, has an accident, an older person who needs assistance, or even from your pets…we don’t really care how the pee got there. It smells and doesn’t look good either. We want to get it out! After it’s out we want to make sure we don’t have to clean our mattress ever again.

Our friend had a very old mattress full of pee stains. She lent to us so we could see if this method actually works. The owner of the mattress did everything he could. He tried to clean it himself but as you can tell you it didn’t work. At all. There was an awful smell! It was so bad that Diana’s husband opened the door to the mud room, he didn’t know we had the mattress in there. When he smelled it he wanted to throw up.

Honestly, I had my doubts about this method and if it would work. After all this mattress had the number 1959 written on it so it’s over 50 years old! I think it’s past it’s 7 year warranty too. Yep, time for a new mattress! We’re up for the challenge though.

How to Get Pee Out of a Mattress

This treatment will help you get pee smell out of mattress and remove the pee stain too. Here’s what you need to assemble to get pee out of your mattress.

3 household items you need. These are inexpensive and you probably have them around the house already:

  1. Hydrogen peroxide.
    Get a large container of hydrogen peroxide if you have a large stain or a lot of surface area to cover. We got a 32 ounce container at the dollar store. We ended up needing most of it for just the upper half and side of the mattress.
  2. Baking soda.
  3. Dishwashing liquid, such as Dawn (brand doesn’t matter)

OPTIONAL but recommended: lavender essential oil. We used doTerra lavender essential oil. Lavender is what spas use to help you relax. It’s known to be calming and helps you fall asleep easier. It has a pleasant smell that almost everyone loves.


We had gloves on to protect ourselves from the pee when we moved the mattress. Also in case we spilled. You may or may not need them. We got most of our supplies at the Dollar Store.

You also need the following supplies:

  • A heavy duty spray bottle with the end nozzle removed. Like this one. If you use a cheap one it WILL CLOG. Then you’ll have to dump the solution on the mattress.
  • A plastic measuring cup.
  • Plastic measuring spoons.
  • Funnel.

Get Pee Out of Mattress: The 5 Easy Steps

Step 1: Pour 8 ounces of hydrogen peroxide into your measure cup.

Step 2: Add 3 Tablespoons of baking soda.

Step: 3 A drop of liquid dishwashing soap.

OPTIONAL: 5-10 drops of lavender essential oil

Step 4: Mix the solution together and pour into your spray bottle. It’s easier to mix before adding but if you have clumps, that’s ok. Spray on all pee spots. Saturate the area so it’s really wet. Don’t forget to spray the sides or top too!

Step 5: Let the mattress dry. Vacuum the residue.

See the video showing exactly how we did it:

I have to say that Diana’s editing skills are getting better with each video! I love the part where she talks about the year written on the mattress. PLUS, there’s a blooper at the end! We’re are so fancy now! The video shows mattress stain removal – not just urine.

IMPORTANT: Now that your mattress is clean, you need to protect it!! Yes, get a “mattress pee protector”! Otherwise you’ll have to clean it again and again. So be sure to use a waterproof mattress protector like this popular one from Amazon.

Best Mattress Protector

If your child (or anyone who has issues with bedwetting) has frequent issues then you might also consider a sheet protector from Linenspa. It’s a pad that goes over the bed sheets that is super absorbent. If there’s pee you can pull it off the bed really fast and wash it without having to wash all the sheets too. It’s a time saver for the right situation! If your pet wets the bed and usually sleeps in one spot, this is a great solution for that too.

That’s it!! It really works! If you have a mattress that has pee on it that you want to get out, try it, you will be amazed!
