Perhaps you are all too familiar with the issue of a wet bed. Maybe it is your child's mattress that's gotten a urine stain. Bed wetting is not a new issue and even young children who have been potty trained can wet the bedding.

Before worrying about it, you should know it is widespread and goes away in time. What you should be doing instead is focusing on the cleaning part. Urine stains and smells can be a bother if you are not sure how to clean pee on a mattress. Thankfully, there are proven tips that can aid you in removing urine stains.

How to clean pee out of a mattress: first thing to do

The first thing you should do in case of a bed wetting accident is to reassure your child that everything is okay. It is likely they are very self-conscious about it and will need some support to get through it. Let them know it is common and that you will work through the process as a team.

Next, it is time to clean. To get urine out of mattresses and sheets, you need to act fast before the fabric can fully absorb the urine. That is why you should wash any soiled clothing and sheets at a high temperature to ensure you eliminate all bacteria and odour. If you think the stains are too tough, pour some detergent and hot water directly on them before tossing them in the washing machine.

Getting urine stains and smells out of mattresses: the process

Once you have taken care of your child and you have put the sheets in the washing machine, it is time to deal with the mattress. It is a well-known fact that urine consists of mostly water (about 95%) and urea. The latter is a waste product, which is responsible for the colour and distinct smell of urine. It should not be left untreated. Here is how to proceed:

Blot the area

Grab some paper towels or a dry towel and blot as much moisture as you can from the affected area. Scrubbing the bed is a no-go as that will only drive the liquid deeper into the mattress. Instead, you should dab the stain and repeat till you can get the remaining moisture out of it.

Prepare a cleaning solution in a spray bottle

You don't need to go all-out on cleaning products when you can mix your own cleaning solution with items from the kitchen. You need warm water and white vinegar. Mix equal parts of them in a spray bottle and give it a good shake.

Apply the mix to the urine stain. Once you have done that, grab a dry towel and blot the area. You will the stain begin to soak and transfer from the bedding onto the towels. Keep at it till you have most of the liquid out. If you are not happy with the smell of vinegar, air out the room for a few hours.

Deal with the urine smell with baking soda

Pee smell can be quite strong, due to the uric acid in it. As you clean urine, you need to work not just on the visible stain but also on the odour of the bed. The vinegar solution should have done some of the work for you. You can go further with baking soda.

Once you are done with the moisture of the stain, sprinkle baking soda on the urine stain. Let it sit overnight for several hours. Baking soda has the power to absorb unpleasant smells from any surface. All you have to do when it does its job is to vacuum the bed and you are done. You can add a few drops of your preferred essential oil and mix it with the baking soda before applying it to the surface. It won't be long before the urine stench is replaced by the pleasant scent of the essential oil.

A heavy-duty treatment for a serious urine stain

Some urine stains are tougher to beat and will require some specifically designed products.

Clean with hydrogen peroxide

To clean with this method you will need about 8 oz. hydrogen peroxide, a few teaspoons of baking soda and 2-3 drops of dishwashing liquid. Mix all of these in a spray bottle and apply a generous amount onto the stain. Let it dry and vacuum the residue of baking soda on top. This should get the urine smells out of the mattress.

Use enzyme cleaner

Enzyme cleaners are specialised cleaning solutions thanks to which you should have a clean mattress when all else fails. They can get urine stains out of your mattress when other solutions struggle. When cleaning with such a product, you must always read the directions on the label and only use the recommended amount. Do not soak the mattress with too much of the solution.

Such a product is designed to break down tough stains on your mattress and other fabric surfaces. When you apply it, you should let it sit for a while as the ingredients are acting quickly to break down the urine spot. If the stain is not gone after one application, you may need to repeat the process.

Prevent the urine from staining your mattress

Apart from working with homemade solutions like white vinegar and specialised products to clean the mattress you or your child sleep on, you should consider some preventive measures.

Use a waterproof mattress protector

This is a very effective way of preventing urine stains from ruining your mattress. The waterproof cover goes on top of the mattress and keeps it safe from spills and stains. You can easily remove it and wash it in case of an incident.

Limit your child's fluids before bedtime

If your child is going through this kind of phase, you should control how much water they drink before going to bed. This is a good preventative measure if they are prone to accidents on the bed. You should also encourage them to use the toilet right before going to bed.


There are a few ways to ensure that your mattress is cleaned from a urine stain. You can start with the DIY method and employ vinegar and baking soda. Make sure to never rub or scrub a stain but blot it instead. If the stain is tough, you can use an enzyme cleaner or hydrogen peroxide to restore your mattress. Being preventive and using a mattress cover also goes a long way.
