💧 Urine Stain & Odor Removal

Step-by-Step Removal Guide
Blot Immediately
If the urine is still wet, blot up as much as possible with paper towels or a clean cloth. Press firmly to absorb liquid from deep in the fabric. Never rub, as this spreads the stain.
Rinse with Cold Water
For washable fabrics, rinse the stained area thoroughly under cold running water from the back side. This flushes out urine before it can set.
Apply Enzyme Cleaner
Apply an enzyme-based pet stain remover or laundry pre-treatment. Enzymes break down the uric acid crystals that cause both stains and odors. Let it sit for 15-30 minutes.
Apply Vinegar Solution
Mix equal parts white vinegar and water. Spray or pour onto the stain. The acidity helps neutralize ammonia odors and dissolve remaining uric acid crystals.
Soak in Enzyme Detergent
Soak the garment in cold water with enzyme laundry detergent for 30 minutes to 2 hours for stubborn stains and odors.
Wash and Air Dry
Wash in cold water with enzyme detergent and add 1 cup of white vinegar to the rinse cycle. Air dry completely—check that the odor is gone before using the dryer, as heat can lock in remaining smells.

❓ Frequently Asked Questions
Why does the urine smell come back after cleaning?
This happens when uric acid crystals aren't completely broken down. They can reactivate in humid conditions or with moisture. Only enzyme cleaners can fully break down these crystals. Avoid ammonia-based cleaners, which can make the smell worse.
Can I use bleach on urine stains?
Avoid bleach, especially on colored fabrics. Bleach can react with urine to create harmful fumes and may set the stain. Use enzyme cleaners or oxygen bleach (OxiClean) instead for safe and effective cleaning.
How do I remove old, set-in urine stains?
Old stains require more intensive treatment. Soak overnight in cold water with enzyme detergent. Apply enzyme cleaner and let sit for several hours. You may need to repeat the process 2-3 times for complete odor removal.
What about urine stains on mattresses?
Blot excess, then spray liberally with enzyme cleaner. Let sit 15 minutes, blot (don't rinse). Spray with vinegar solution, let sit, blot again. Sprinkle baking soda over the area and let sit overnight to absorb odors. Vacuum thoroughly in the morning.
