Why is Pet Urine So Hard to Remove?

Pet stains pose a challenge to clean and deodorize, but pet urine is especially difficult to remove. Urine stains can persist after several cleanings, and that urine smell can linger forever.

Dog and cat urine is chemically very different from human urine. While all urine is typically 95% water, dogs and cats possess higher levels of uric acid. Uric acid forms crystals which become embedded in carpets and upholstery. That combined with the resulting bacteria causes the odors associated with per accidents. Additionally, cats possess an extra amino acid in their urine called felinine that adds a terrible smell to their urine. Even when it appears a urine stain has been completely removed, the uric acid crystals, bacteria, and felinine can remain invisibly with a pronounced and long-lasting odor.

The lingering effects of pet waste and urine can not only damage or discolor your carpet and upholstery, they can also pose health risks to your family by harboring bacteria. The remaining smell can also condition your pet to revisit the spot for repeated bathroom functions.

Most cleaning products were formulated to address dirt. Very few have the ability to break down more complex organic compounds, and hardly any can truly tackle the structures and odors presented by uric acid crystals and felinine. At best, they can simply mask the odor with a stronger scent, but the smell of urine will probably return with time.

Earthworm® Pet Stain & Odor Eliminator uses naturally-occurring enzymes to break down organic materials, including uric acid crystals and felinine. It is safer for your family and pets than harsh cleaners, and more effective at permanently removing odors from your carpets, furniture, and fabrics.
