You can purchase a black light rather inexpensively from pet stores or online. Using paper towels, blot up as much of the urine as possible if the surface is fabric or carpet. With these surfaces, there is a danger of the urine soaking into the fibers of the material. Use a gentle dabbing motion to blot up the urine. If you’re concerned about using a lot of paper towels for environmental reasons, use a cloth towel or rag or even old clothes that can be thrown away. You can also use a wet vacuum to «suck up» the urine if you have one on hand.
This will lift more of the cat urine than blotting. Do not use a steam cleaner as at this point in the cleaning process the heat can cause the odor to last much longer and be more difficult to remove. Avoid rubbing in the stain. Scrubbing away at the stain at this stage will only cause it to sink in deeper. If the stain is already dry, pour cold water on the stain, and blot. Stand on the wet spot if it is on a carpet.
This will help to bring up the stain from the surface. Treat the soiled area with a stain remover. You can either use a commercial product or make your own stain-removing solution using common household products. See below for instructions for both cleaners. Look in particular for an enzymatic cleaner. Enzymatic cleaners are specifically designed for cleaning urine-soiled areas. These types of cleaners break down the enzymes in the cat urine and neutralize the odor.
They can usually be purchased at any pet store. Well-known brands include Knock Out, Urine Off, and Anti-Icky Poo. Enzymatic cleaners break down the uric acid in cat urine into carbon dioxide and ammonia. These are both gasses that will then easily evaporate and thereby neutralize the odor. These cleaners work on both fresh and old urine stains. Some cleaners may have their own specific instructions for use so make sure to go over these carefully before applying the cleaner to the soiled area.
Always follow any instructions that come with the specific cleaner you have purchased. Failure to follow the proper instructions could result in permanent damage to your furniture or surface. Always test out the product on a small, out-of-sight area to see whether the product results in any damage or discoloration to the area. If you notice anything unusual, stop using the product. Either purchase a different commercial product or try the homemade solution below. If you don’t see anything, then go ahead and apply the product to the soiled area.
Soak the affected area with the enzyme cleaner. Let the cleaner sit for 10-15 minutes so it can soak into the stain. Then blot up as much of the cleaner as you can using paper towel or a rag. Let the affected area air dry. This is very important because the cleaner needs this time to effectively break down the uric acid salts and then allow the gasses to evaporate. Close off the affected area.
Cats are naturally attracted by the enzymes in urine and will be drawn to urinate in areas that have previously been urinated in. Cover the area loosely with something like aluminum foil or an upside-down laundry basket. This will not only keep the cat from attempting to pee in the same spot while the cleaner does its job but also keep any members of the household from stepping on the area. Repeat the process as needed until the stain and smell subside. Gather the ingredients to make a homemade cleaner. Vinegar helps to kill any bacteria and neutralize the odor. This mixture works well for treating both old and new stains. Mix a two-parts water and one-part vinegar solution. Pour this mixture over the stain and soak for about 3 to 5 minutes. Then blot the area to soak up the excess liquid. Note that vinegar should not be used on marble or stone surfaces. Sprinkle baking soda over the affected area.
