How do I Get Cat Urine Out of Sub Flooring?

Cats can ruin floors with a urine accident.

Cats can ruin floors with a urine accident.

Cat urine has a distinct and unpleasant smell that all cat owners know. Most cats experience a urine accident at some point. Cleaning the urine up correctly and completely is important. Cats will mark again in an area where they can smell their own urine.

Soak up as much of the urine as possible with paper towels. Remove all traces of liquid.

Soak the area with a solution of vinegar and water. Wipe away. Repeat. Do this until you cannot see the stain.

Shake baking soda onto the spot if you can still detect an odor. The baking soda will help draw out the urine and will deodorize the smell. Let baking soda sit for several hours. If you wipe away and the stain and smell is gone, you may be done.

Spray the area with a liquid enzymatic cleaner made specifically for pet urine. This cleaner will dissolve the urine, removing the smell and odor. Make sure you soak the area enough that the cleaner will go through the carpet to the sub flooring. Let air dry. Rinse with clean water. Repeat if necessary.

Pull up the carpet and sand the sub flooring with a power sander if the stain and odor persist. Remove all trace of the stain with the sander. If the stain is this set, you will probably be able to see the stain as a brown or black spot when you pull the carpet up.

Items you will need

  • White vinegar
  • Baking soda
  • Water
  • Paper towels
  • Enzymatic cleaner
  • Power sander

Tip

  • Keep your dog and other pets away from the area so they don't ingest the cleaning solution while you are cleaning.
