How to Remove Cat Urine from a Couch Cushion: Fresh and Set-In Odor

Set-In Cat Urine on a Couch Cushion

For dried urine, you’ll need to re-wet the area to dissolve the uric acid crystals. Here’s a method that works for many cushions:

1. Re-wet the stained area with cool water. Use a spray bottle or a damp cloth to saturate it, but don’t soak the cushion.
2. Apply a commercial enzyme cleaner designed for pet urine. Follow the label instructions. Enzyme cleaners break down the uric acid that causes the odor.
3. Let the enzyme cleaner sit for the time specified on the label (often 10–15 minutes). Do not let it dry completely.
4. Blot up the excess with a clean cloth.
5. Rinse the area with cool water and blot dry.
6. Allow the cushion to air dry completely. This may take 24 hours or more.

If the odor is still noticeable after drying, repeat the enzyme treatment. Sometimes it takes two or three applications for set-in urine.

What Not to Do

• Don’t use steam cleaners on urine stains. Heat can set the stain and odor permanently.
• Avoid bleach or ammonia-based cleaners. Ammonia can attract cats to re-mark the spot, and bleach can damage fabric or cause fumes.
• Don’t rub the stain. Rubbing spreads the urine and can damage the cushion fibers.
• Skip the baking soda and vinegar as a primary treatment. While they can help neutralize odors, they don’t break down uric acid like an enzyme cleaner does.

Fresh vs. Dried: Why It Matters

Fresh urine is easier to remove because it hasn’t had time to crystallize. Dried urine requires re-wetting and an enzyme cleaner to break down the uric acid. If you’re dealing with a fresh accident, you might get away with just dish soap and water. For dried accidents, enzyme cleaner is your best bet.

Surface-Specific Warnings

Before using any cleaning solution, test it on an inconspicuous area of the cushion, like the bottom or a corner. This ensures the fabric won’t discolor or shrink.
