Why Dried Dog Urine Is Tricky

When urine dries, it leaves behind uric acid crystals. These crystals can cause a lingering odor and can even attract your dog to re-mark the same spot. The key is to break down those crystals with an enzymatic cleaner, not just mask the smell.

Cotton is a natural fiber that absorbs liquids easily, so the urine may have soaked deep into the cushion or fabric. That means you need to treat the area thoroughly, not just the surface.

What to Do First

If the urine is already dried, start by gently scraping off any crusty residue with a dull knife or spoon. Be careful not to rub or scrub, as that can push the stain deeper into the cotton fibers.

Next, blot the area with a clean, dry cloth to absorb any remaining moisture. Do not press hard; just dab gently.
