How to Clean Cat Urine on a Mattress

interior #9 image by turkinson from

Cats urinate on furniture for different reasons. Sometimes a cat will urinate because the litter box is inaccessible or too dirty. Other cats spray urine to mark their territory. Cat urine has a pungent smell that can be offensive. This is especially true when they urinate on a mattress that you sleep on. Luckily, there are ways to remove cat urine smells from your mattress using household products and a little effort from you.

Remove any damp urine as soon as possible using clean paper towels. Press the paper towels on to the spot to soak it up. If the spot is dry and you are unsure where it is, use a black light to find it. Pass the black light over the mattress and it the spot will glow under the black light.

Use a plastic squirt bottle to make a mixture of 1 part water and 1 part white distilled vinegar.

Spray the spot from Step 1 with your vinegar mixture. You want the spot completely saturated. Leave the spot to dry until it is just damp. If you need to dry the spot quicker, use some dry paper towels to dab the area or use the upholstery attachment on a steam cleaner to suck up the moisture.

Add a layer of baking soda over top of the spot. You want the spot to be completely coated.

Mix together 1 tsp liquid dish detergent and 1/4 cup of hydrogen peroxide. Pour the mixture onto the baking soda.

Scrub the spot with a scrub brush or old toothbrush. You want to rub the baking soda until it dissolves in the dish detergent mixture.

Leave the spot to dry completely. Vacuum up the dried baking soda spot.

Clean the damp urine spot as soon as possible the same way you would in the first method. If the spot is dry, use a black light to locate it.

Use a plastic squirt bottle to mix together 1 cup hot water and 5 drops of a disinfecting mouthwash.

Spray the urine spot with your mouthwash mixture. You want the spot completely saturated.

Leave the spot to dry thoroughly. If the odour is not completely removed after the first treatment, you can repeat the process as necessary.
