How to Remove Pet Urine Stains and Odor from Carpet
Plain cleaners mask pet urine odor but do not remove it. Enzyme cleaners break uric acid down into water and gas. In Tucson's dry air, urine dries and forms crystals fast. These crystals wake up when wet again. That is why old stains smell worse on damp days.
Apply Enzymatic Cleaner
Soak the stain with an enzymatic pet cleaner. Do not use too little. The enzymes need to reach as deep as the urine did. Let it sit for 10 to 15 minutes.
Blot and Dry
Blot up the cleaner with clean cloths. Do not scrub. Let the area dry fully before you walk on it. Re-wet old stains before applying the enzymatic cleaner.

Why Enzymatic Cleaners Are Essential
Plain carpet cleaners only mask the smell. Enzyme cleaners digest the uric acid crystals. Vets and carpet makers both suggest them. Look for the word uricase or enzyme on the label.
In Tucson's dry air, uric acid crystals form fast. This makes quick action more important here than in wet cities. Old stains may need two or more enzyme cleaner passes to fully clear.

How to Remove Pet Urine Stain Carpet Odor FAQ
Why does pet urine smell worse after I clean the carpet?
Re-wetting old urine crystals brings the odor back. Use an enzyme cleaner each time to break down the crystals. Do not just wet them.
Can I use vinegar or baking soda instead of an enzyme cleaner?
Vinegar and baking soda cut odor short-term but do not break down uric acid. Only enzyme cleaners remove the source of the smell.
