How to Remove Dried Cat Urine from a Wool Rug

1. Blot the area with a dry white cloth to absorb any remaining moisture. Press down firmly, but do not rub, as rubbing can push the urine deeper and damage the wool.
2. Apply an enzymatic cleaner specifically formulated for pet urine. These cleaners break down the uric acid crystals that cause the odor. Follow the product instructions for dilution and application. Spray or pour the cleaner directly onto the stain, making sure to saturate the area but not soak the rug.
3. Let the cleaner sit for the recommended time, usually 10 to 15 minutes. This gives the enzymes time to work on the urine. Do not let it dry completely.
4. Blot the area with a clean, dry cloth to lift the cleaner and dissolved urine. Press down gently and repeat with fresh cloths until no more moisture is absorbed.
5. Rinse the area with cool water to remove any remaining cleaner. Use a spray bottle or a damp cloth to apply water, then blot again. Repeat this step until the water runs clear.
6. Blot up excess moisture with a dry towel. Press firmly to absorb as much water as possible.
7. Allow the rug to air dry completely. Keep the area well-ventilated and avoid walking on it until dry. You can place a fan nearby to speed up drying, but do not use heat, as it can set the stain.

What Not to Do

• Do not use steam cleaners or hot water. Heat can set the protein in the urine and make the stain permanent.
• Do not use bleach or ammonia-based cleaners. These can damage wool and may react with urine to create harmful fumes.
• Do not scrub the stain. Scrubbing can fray the wool fibers and spread the stain.
• Do not use a regular carpet cleaner unless it is specifically labeled safe for wool. Many contain harsh chemicals that can strip the natural oils from wool.

Fresh vs. Dried Urine

Fresh urine is much easier to remove because it hasn't had time to set. If you catch it early, blot up as much as possible, then follow the same enzymatic cleaner steps. Dried urine requires more time and repeated treatments, as the uric acid crystals have bonded to the fibers.

For dried urine, you may need to apply the enzymatic cleaner more than once. After the first treatment, let the rug dry completely, then check for any remaining odor or stain. If needed, repeat the process. Patience is key.

Wool-Specific Precautions

Wool is a protein fiber, similar to hair, so it is sensitive to alkaline cleaners and high pH. Enzymatic cleaners are generally safe for wool, but always check the label. Some products are not suitable for wool, so look for one that is pH-neutral or specifically designed for delicate fabrics.
