How to remove cat urine from carpet


Q: How do I take away cat urine from carpet?

A: Cat urine is particularly hard to offer with — worse, even, than pet urine, according to Jessika James, senior coach for Find out to Restore (, which delivers lessons for cleaning gurus that are sanctioned by the Institute of Inspection, Cleaning and Restoration Certification (IICRC). She is also a previous board member of IICRC, the industry’s expectations-environment firm.

The explanation cat urine is so confounding: It incorporates hormones and pheromones in addition to urea, uric acid and far more, James reported.

On tough surfaces, it is effortless ample to wipe away the urine. On carpets or porous surfaces, it helps make sense to blot up as considerably liquid as you can as quickly as feasible, but even if you function immediately, adequate urine will possibly continue being to result in a system that can final result in smells from the similar loved ones of chemical compounds that can make skunks stink. According to the Business office for Science and Modern society at McGill University, bacteria improve in cat urine that isn’t cleaned up promptly, which releases an ammonia scent. Further more decomposition emits mercaptans, which are sulfur-made up of molecules located in skunk spray, rotting meat and other obnoxious points.

The most effective way to hold cat urine from stinking up a house is to use an enzyme cleaner. The enzymes velocity up decomposition and crack the urea into carbon dioxide and ammonia, which evaporate rapidly, protecting against the reactions that can guide to skunk-variety smells. These cleaners include things like Urine Absent stain and odor eliminator ($13.99 for an 8-ounce bottle from and Nature’s Miracle superior stain and odor eliminator ($13.55 for 32 ounces from Amazon).

But there are a several caveats about working with these goods.

1st, James explained, even if the label says it’s both equally an odor eliminator and a stain remover, it ordinarily is not, for the reason that the two styles of chemistry are incompatible. Enzymes avert smells but do not get rid of stains. Stain removers have a tendency to be oxidizers, employing cleansing agents this sort of as hydrogen peroxide. “They consume each other,” James stated.

Start by combating the odor, then the stain. It is essential to start out with an enzyme cleaner, not a carpet shampoo, James explained, for the reason that detergents can leave a residue that can interfere with the enzyme’s efficiency. Urine Away’s label says it performs even if soaps and detergents have been used, but applying soap first does not make the urine easier to clean up, so why chance it? Nature’s Miracle warns that making use of other cleaners and detergents first may chemically “set” stains that will then be unattainable to remove.

Also, read through the label for surfaces in which the enzyme cleaner should really not be used. These generally consist of bare wood, leather, suede, silk or wool specialty fabrics. Labels generally propose tests a compact patch of carpet in an out-of-the-way site first to assure the colour isn’t impacted. James claimed this is a unique problem with nylon carpet, which is a lot more prone to losing coloration and turning into stained than other carpet fibers.

For an enzyme cleaner to work, it demands to saturate the fibers and penetrate as deeply as the urine did. Do not just spray or sprinkle it on lightly pour it on. If the urine soaked into the pad, that requires to be soaked with the cleaner, too.

The enzymes help change the urea into gases that evaporate immediately, but they really don’t clear away the other substances in cat urine, which generally leaves patches of the carpet sticky, James mentioned. When people wander above the carpet right after it is dried, the carpet appears to grow to be stained, but the “stain” is just grime, she claimed.

To avert this, the space requires to be completely rinsed with clean h2o following the enzymes have labored, James explained. For home owners striving to handle pet mishaps on their have, the finest way is to sponge on clear water, then blot it out by spreading a thoroughly clean, dry towel about the space and pressing down. Rotate the towel as essential. Do not rub again and forth, because this may make the fibers fuzzy or pilled.

For the very best outcomes, James explained, simply call in a skilled carpet cleaner with equipment that can flush the carpet with drinking water, then extract the moisture, so the carpet isn’t left soggy. Professionals can also give tips about taking away stains or grime remaining by home treatment plans of cat urine.

If your efforts to combat the smells really do not appear to be to be doing the job, it is achievable you have not located all of the urine deposits. Cats, primarily males, like to mark territory and may well leave urine in out-of-the-way places. Test looking when the space is dark, and use a flashlight with 9 to 12 bulbs that make ultraviolet gentle, these types of as the UV Stain Detective LED black light-weight ($13.97 from Amazon). The light will make dried urine glow in the dark, so you know which spots to take care of.

If that does not do the job, or if your cat appears to be returning to the exact same place, you may need to pull up part of the carpet, change the pad and seal the subfloor with shellac. In serious conditions, aspect of the subfloor could need to have to be replaced.
