- 15 ounces hydrogen peroxide
- 2 tablespoons baking soda
- 2 squirts of liquid hand soap.
Mix in a plastic container (don’t use metal) with a plastic spoon. Do not shake this mixture. Discard after use. Apply this solution to cat urine stains or odour areas, and then rinse away with warm water.
- 1 part distilled white vinegar
- 2 parts warm water.
Combine the two ingredients into a plastic spray bottle.
- Baking soda.
Apply baking soda to the wet urine stain. This will draw out the urine. When the baking soda turns yellow from the urine, remove and apply some more. Repeat until the baking soda stays white. If possible, leave on the mattress overnight. The following day, vacuum it off.
Cleaning cat urine
- If the urine is still wet, blot up as much as you can with paper towels. Stand on the paper towel to help absorb as much moisture as possible.
- Using one of the above recipes, spray the area thoroughly (spot testing first to avoid damaging your flooring) and spray the solution onto the affected area.
- Leave for 30 minutes and then blot dry with paper towels or a damp cloth.
- Repeat if necessary.
Locating cat urine
Old cat urine can be a particular problem because as it is the breaking down of the urine that causes the offensive odour. If you can’t find where your cat has urinated or sprayed, a black light can be used. This will highlight any areas your cat has soiled. To use, turn out your lights and move the black light around the floor, walls, and furnishings to help identify soiled areas. Cat urine will glow green.
