Why Dried Dog Urine Is Harder to Remove
When urine dries, the uric acid crystallizes and bonds to the fabric fibers. Water alone won't dissolve it. That's why you need an enzymatic cleaner, which breaks down the uric acid and other compounds in the urine. Enzymatic cleaners are specifically designed to tackle pet stains and odors.
Polyester is a synthetic fabric that is generally durable and resistant to moisture, but it can still hold onto odors. The good news is that polyester is less absorbent than natural fibers like cotton, so the urine may not penetrate as deeply. However, if the urine has dried, it can still leave a visible stain and a persistent smell.
