This will soak up as much urine as possible, diminishing the possibility of the pee soaking into your rug or upholstery. Use water and a few drops of soap to dilute the damp spot. Get a bowl of warm water, and put a few drops of mild soap in it. Use a clean towel to wipe the wet spot with the soapy water, blotting with a dry towel.
You can do this a few times until no traces of the original cat spray remain. Sprinkle the spot with baking soda. Sprinkle the damp spot with a few tablespoons of baking soda, which is a natural cleaning agent. Let your baking soda sit on the peed spot overnight. Baking soda is non-toxic and is an ingredient in most kitty liters. If your cat seems interested in eating the baking soda, however, you can block off the area to keep your cat away.
Vacuum the baking soda up. If your cat sprayed the carpet, use a full-size vacuum to clean up the baking soda the next morning. Go over the area as many times as necessary to suck up all the powder, so the area is clean to the touch. If your cat peed a mattress or another upholstered surface, use a handheld vacuum to clean up the baking soda. Even after cleaning up the area, some traces of urine will likely remain. Use an enzyme-based cleaner to eliminate any remaining traces of spray. Fully saturate the area, and allow the cleaner to air dry.
Use water to dilute the urine-stained area. If your cat’s urine stain has set for a long time, you will first need to dilute the stain. Get a bowl of warm water, and use a two clean towels to alternately dampen and blot dry the stained spot. Do this several times to dilute the stain as much as possible. Remember to only dampen the area. Getting it too wet could cause the stain to spread. You may want to wear rubber gloves for this.
Your towels may start to take on some of the odor. However unpleasant, this is what you want, as it indicates you are drawing the stain out of the soiled area. Swap out your towels and continue diluting the stain as much as possible. Once you have diluted the stain as much as possible, use an enzyme neutralizer, such as Nature’s Miracle, Odoban, or Zero Odor. These cleaners break down protein-based molecules in cat urine. After doing a test for colorfastness on a hidden area of your carpet or upholstery, spray the area so that it is completely saturated with the cleaner, and allow it to air-dry. Air drying can take multiple days, so it may be helpful to cover the area with plastic to keep the cleaner in place and away from your cat and other household members.
Launder or replace any items that retain traces of spray. If stained areas remain after using the enzyme neutralizer, remove slipcovers from any soiled items and launder with cool water. Air dry to avoid shrinkage in the dryer. If your cat has sprayed a carpet, consider replacing the rug pad beneath. These can contain synthetic materials that are more difficult to clean. Start by cleaning the area with a damp cloth. Remember that cats spray vertically, so you will need to clean the whole area including the floor, baseboards, and lower part of your wall.
Start by cleaning the area with a damp cloth to remove any wet spots or visible traces of the urine. From there, you can apply a stronger cleaner as necessary. Try a hydrogen peroxide mask. This method is particularly useful if the urine left a stain. Wring the towel if necessary, and place the towel on the sprayed area. Let the towel sit for 2-3 hours to clean the offending spot. If you need to press the towel against a baseboard, use something disposable, such as a Tupperware, to wedge the towel against the wall. If the floor or baseboard is still damp when you remove the hydrogen peroxide towel, wipe the area dry with a clean cloth. Use an enzyme-based cleaner formulate for wood floors. An enzyme-based cleaner is the best way to help you remove odor from your floors, but wood floors need a gentler formula than carpet. Use an enzyme-based cleaner formulated for wood floors by wetting the sprayed area with the cleaner and allowing it to air dry. You may want to test the cleaner on a small area of your floor before applying it to a highly visible place to ensure it won’t cause any damage. Enzyme-based cleaners should not be used directly on untreated wood or subflooring, as this could cause damage. Sand the wood down and refinish.
