Steps to Get Urine Out of Mattress
To remove already dried pee stains, you need to use hydrogen peroxide or baking soda. We are going to explain the cleaning process in steps so that you can confidently remove the urine odour and stain.
1. Remove Your Bedding
First of all, strip your mattress and put your bedding into the washing machine. Get All your sheets and comforters into the washing machine. After doing this, if you discover your linen with urine stains and the smell still lingers, add a cup of white vinegar and wash it again.
2. Don’t Scrub but Gently Blot
If you scrub, the scrubbing will spread the urine around and force it deep into the mattress. So gently blot up as much of the surface urine as possible by using a towel. And then take the towel into the washing machine.
3. Make a Cleaning Solution and Spray the Stain
Mix a solution of two parts cold water, one part white vinegar, and a small amount of laundry detergent in a bottle. You can add a few tablespoons of laundry detergent for a standard spray and more if you have a large bottle. Spray the stain and don’t be afraid to soak it.

4. Let the Solution Soak
Now leave the solution-soaked mattress for a minimum of 10-15 minutes. You have to blot it up again. Use a clean cloth to soak up the excess liquid.
5. Apply Baking Soda
Use baking soda to cover the entire surface of the soiled area. Allow it to sit here for 8 to 10 hours. Close your room and prevent your kids and pets from making a baking soda mess.
6. Remove the Dry Baking Soda with a Vacuum Cleaner
Finally, use a hose attachment, and vacuum the dried baking soda from your mattress. Make sure the powder is completely dry; otherwise, you will run the risk of damaging your vacuum. Alternatively, try to use a dry vacuum cleaner to clean up damp powder. After completing the vacuuming, inspect the mattress and repeat steps 3 through 6 to eradicate any lingering odor or stains. It is the last step you must consider while cleaning urine out of mattress.
Consider Mattress Protector
Use the best mattress protector to protect it against urine or any liquid. It works as a barrier between the liquid and the bedding. Most mattress protectors are designed to be waterproof, which means that they are resistant to the penetration of water or other fluids.

When the urine comes into contact with the protector, the liquid cannot seep through it and into the mattress. Instead, the pee remains on the surface of the waterproof mattress cover, so it can easily be wiped away or washed away. Some mattress covers also have additional features. For instance, they have absorbent layers or antimicrobial properties that help further protect against urine.
It saves you from water damage. They minimise the friction you place on the cover fabric, preventing lint balls on the mattress from forming. Overall it is an effective product used for better maintenance of your mattress.

By following the above given step-by-step process about how to clean urine out of mattress, you can restore your mattress to a fresh state.

Frequently Asked Questions (FAQ)

2. What household items do I need to clean urine from a mattress?
You will need white vinegar or hydrogen peroxide, cold water, laundry detergent, clean towels, a spray bottle, baking soda, and a vacuum cleaner for the process.
