How to Remove Cat Urine from a Polyester Couch

Cat urine on a polyester couch is one of the toughest household odors to tackle. The longer it sits, the deeper it soaks into the fabric and padding, making the smell harder to remove. But with the right approach and an enzymatic cleaner, you can break down the uric acid crystals and eliminate both the stain and the odor.

Polyester is a synthetic fabric that resists moisture, but it can still trap urine in the fibers and the cushion foam underneath. Acting quickly is key, but even dried accidents can be treated successfully with patience and the right steps.

What to Do First

If the urine is fresh, blot up as much as possible immediately. Use paper towels or a clean, dry cloth. Press down firmly to absorb the liquid, but do not rub, as that can push the urine deeper into the fibers. Continue blotting until the area feels only slightly damp.

If the urine has dried, start by gently scraping any crusty residue with a dull knife or spoon. Then vacuum the area to remove loose particles.

How to Remove Cat Urine from a Polyester Couch

Follow these steps for both fresh and dried accidents. Always test any cleaner on a hidden area of the couch first to ensure it does not cause discoloration or damage.

1. Blot the area with paper towels to remove as much urine as possible. Press firmly and repeat until the towels come up mostly dry.
2. Apply an enzymatic cleaner specifically designed for pet urine. Saturate the stained area thoroughly, but do not soak the cushion to the point of dripping.
3. Let it sit for the time recommended on the product label, usually 10 to 15 minutes. This allows the enzymes to break down the uric acid crystals.
4. Blot again with clean paper towels to lift the cleaner and dissolved urine. Do not rub.
5. Rinse the area with a small amount of cool water on a clean cloth. Blot to remove any soapy residue.
6. Allow it to air dry completely. Keep pets away from the area until it is fully dry.
7. Check for odor once dry. If the smell persists, repeat the process. For dried or set-in urine, you may need to repeat the treatment several times.
