If you have cat urine streaks on your wall, they're most likely from an unneutered male who is marking his territory. Not only are the streaks unsightly, they're smelly as well. If your walls are white, you may notice yellow stains on them from the urine. Although the urine stains may not show up as well on darker walls, you'll still be able to notice the strong, ammonia-like odor. To remove the pungent smell and stains from a wall, you can use an inexpensive, non-toxic homemade solution or a commercial enzymatic cleaner.
To Remove Cat Urine Stains and Smells from Walls:
Wipe away the fresh, wet urine as soon as possible to reduce the chance of streaking and staining. Use a clean, absorbent towel, such as a microfiber cloth, to blot up as much of the urine as you can. Use several towels if necessary to remove all of the urine.
Create a cleaning solution by mixing 50-percent distilled white vinegar with 50-percent water in a plastic spray bottle. Spray the mixture directly onto the urine streaks, being careful not to oversaturate the area, which could make the stains spread. For more stubborn stains, you can allow the solution to sit on the walls, penetrating the stains, for several minutes before wiping it off. Avoid using vinegar on marble or stone walls, as it can chemically erode the stone.
Not only will vinegar remove the stain and deodorize the wall, it will also sanitize and disinfect the area as well.
Blot the vinegar solution up with another soft, absorbent cloth. Repeat the process as often as necessary until the urine streaks and odor are gone.
If the urine stain or odor still remains on the wall, use a commercial enzymatic spray cleaner especially formulated for use on the type of walls you have, such as painted or wallpapered. Test a small, inconspicuous area of the wall first to check for colorfastness.
Spray the cleaner onto the streaks and leave it on the wall for the amount of time specified by the product manufacturer. It's important to allow the cleaner to air-dry, rather than wipe it up, as the enzymes break the uric acids in cat urine down and transforms them into a gas as it dries.
If the stains or smell still remain, you can paint over the area with a fresh coat or two of a high-quality, odor-blocking paint. To find out more, speak with someone like Chem Dry Springfield.
