Home Remedy: How to Remove Cat Urine Smell

The harsh odor of cat urine can ruin the overall ambiance of a room or home. The longer the cat urine sits unclean, the more bacteria grow, causing an awful ammonia smell. Cats make the mistake of urinating in places other than the litter box for various reasons including dirty litter boxes, behavioral problems or health-related issues. The hardest step in removing cat urine odor is finding the source of the problem. Once you find the problem area, you can begin to remove the offensive odor with chemical cleaners and common household items.

Remove harsh cat urine odors from the home with simple household items.

Step 1

Wipe up puddles of cat urine right after they happen, using paper towels.

Step 2

Turn off all lights in the immediate area. Turn on the hand-held black light and use it to locate all areas of cat urine on carpeting, upholstery or any flooring and wall surface. Use chalk to outline the found cat urine areas. Hand-held black lights are available at most pet stores.

Step 3

Pour equal amounts of white vinegar and water into a spray bottle. Spray the vinegar solution onto the cat urine stains you found and outlined with chalk. For walls and hard surfaces, spray the vinegar mixture on the stain and blot away with a water-dampened towel. Continue to spray the urine spot until it is fully saturated. Vinegar eliminates the ammonia in the cat urine. Leave the solution to soak into the fibers of the carpet or upholstery until it is almost dry.

Step 4

Turn the wet/dry vacuum on. Vacuum over the area until you remove all liquid. Sprinkle at least a handful of baking soda over the vacuumed area. Pour 1/4 cup of hydrogen peroxide into a cup, add 1 tsp. of dish soap and pour the solution over the baking soda area.

Step 5

Don gloves to protect your hands and rub the solution into a paste. Work the paste into the urine area to remove all traces of odor. Allow the solution to dry, then vacuum the paste away.

Step 6

Apply a chemical stain and odor remover specially formulated for cat urine on larger surfaces. Refer to the cleaner's instructions on how to apply the product.
