How to Clean Pee From a Mattress

When caring for children, incontinent adults and pets, it is a good idea to know how to remove urine stains and odors from mattresses. Accidents happen, and improper cleaning can lead to unpleasant smells and a build-up of bacteria that no one wants to think about sleeping on. Cleaning the bedding itself is easy and is simply a matter of tossing sheets and blankets into the washing machine. The mattress requires special treatment though, but can still be cleaned with ease. This technique works on both pet and human urine and is excellent for eliminating the odor urine can leave behind.

Step 1

Gather the supplies you'll need to tackle the job. You'll want a bucket, cold water, vinegar, baking soda, detergent, paper towels and a vacuum cleaner with a hose attachment. A fan or blow dryer will also come in handy to help dry the mattress when you're done.

Step 2

Blot the stain gently with some paper towels if it is still wet. You want to soak up the urine but you don't want to push it further into the mattress, so blot with a light touch. Consider wearing protective gloves. You can skip this step if the stain has already dried.

Step 3

Mix together 2 parts cold water and 1 part vinegar. Add a pinch of detergent as well and then dab the combined mixture liberally onto the stain with a paper towel. If you prefer, you can also place the mixture in a spray bottle and spray it onto the stain. Wait about 15 minutes for the vinegar to work on the stain and the smell before moving on to the next step.

Step 4

Sprinkle baking soda liberally over the stain and allow the mattress to sit undisturbed for another 10 minutes.

Step 5

Use the vacuum cleaner hose attachment to lift the baking soda back off the mattress.

Step 6

Open a window or set a fan in the room to allow air to blow across the mattress. This speeds the drying process. When the mattress is completely dry, remake the bed. When you do, consider adding a waterproof mattress cover to make future accidents even easier to clean up.

This method works for cleaning urine-stained mattresses most of the time. But urine can be a tough stain to remove, and it is possible you will still notice an odor after cleaning up dog or cat urine. If you do, use an enzyme-based cleaner from your local hardware store or veterinarian to remove any lingering odors.
