How to Remove Urine Stains and Odors from a Mattress?

Remove Urine Stains from a Mattress

How do I remove urine stains from mattress? This is a common question asked by many parents who have small kids. Any parent who has kids is likely to experience or has experienced the problem of removing urine from mattresses after their kids have accidentally peed during nighttime.

I have a small daughter, and earlier this week, she peed in her toddler bed and since I wasn’t feeling well, I couldn’t wash her bed sheets and thus the laundry piled up. We have an extra king-sized bed in one of our rooms reserved for guest. So I let my daughter sleep in this bed for several nights before I recover to put her bed in order and wash all the bed sheets and mattress.

So, over the weekend when I pulled off the sheets of the guest bed, where my daughter was sleeping, I found out that she had also peed. I was so disgusted because that was a guest room and the mattress is very expensive. I had to look for ways to get rid of urine in mattress.

While on my research, I came across a forum where a lady in the UK had raised the same question; how do I remove pee from a mattress? There was a long reply from a concerned participant who offered two methods to cleaning urine. In the first method, she suggested the use of a mixture of dish soap, vinegar, and baking powder. This seemed simple. The other method involved the use of baking powder, vinegar, towels, and vacuum. So I decided to give the first method a trial;

How to Get Rid Of Pee Stains from a Mattress

Method 1

Things you will need

  • Measuring cup
  • Funnel
  • Tablespoon
  • Vacuum
  • Heavy duty spray bottle
  • 8 ounces/237ml hydrogen peroxide 3%- you can get this in a brown bottle in most stores and pharmacies.
  • One drop of liquid hand dishwashing soap
  • 3 tablespoons/45g of baking soda


Mix all these ingredients in the spray bottle. Do not shake the bottle, and you have to use the resultant within 20 minutes. Do not store unused solution because it will eat out the bottle and leak out. This mixture is only effective when used immediately after mixing. This is because the mixture is reactive for only a short time. After applying on the pee stain, you should see it disappearing within 5-10 minutes.

Once the mattress has dried, baking soda film might remain; use a vacuum cleaner to wipe it off. I read somewhere that this method works well when it comes to removing pet urine stains. However, I’m yet to test it in that capacity.

Method 2

Things You Will Need

  • A roll of paper towels
  • Spray bottle
  • Vacuum
  • Toothbrush
  • Baking soda
  • Distilled white vinegar


(If the urine has not dried up, use paper towels to dry most of it. However, avoid pressing the towels hard into the spots as this may push the urine further into your mattress)

To remove the stench of urine smell from your mattress, spray distilled white vinegar around the stain until they are soaked up. Use paper towels to push the vinegar deeper into the mattress to get out all the urine smell. If the stain remains stubborn, use a toothbrush to rub the vinegar in. Vinegar smell can be overwhelming, therefore it is advisable that you apply it outside the house. If you have no space out the house, open the windows. After applying vinegar, vacate the room for about 5-10 minutes to allow the vinegar smell to go away.

Now use layers of fresh paper to dry the remaining vinegar from your mattress.

Sprinkle baking powder around the spot and let it settle for several hours; leave it on the spot for as long as possible. The baking is meant to remove the vinegar and its odor and therefore will begin to clump up as it soaks in the vinegar.

By using a vacuum cleaner, remove the dried baking soda from the mattress until it is clean.

There you have them; both methods work effectively.

Keep in mind that you can employ any of the above methods repeatedly; they will not discolor your mattress. If you find one method complicated, you can try the other one. After removing the pee stain from your mattress, be proactive next time and use sealed waterproof mattress protector before making up your child’s bed.
