How to Remove Dog Urine from a Nylon Carpet: Fresh and Set-In Odor

1. Blot the area with paper towels or a clean cloth to absorb excess urine. Press and lift, repeating until no more liquid transfers.
2. Rinse with cool water by lightly spraying or dabbing the area with a cloth dampened with cool water. Blot again to remove diluted urine.
3. Apply an enzymatic cleaner specifically designed for pet urine. Follow the product instructions, usually spraying or pouring enough to saturate the affected area.
4. Let it sit for the recommended time, often 10-15 minutes, to allow the enzymes to break down the uric acid.
5. Blot up the cleaner with a clean cloth, then allow the carpet to air dry completely. Avoid walking on it until dry.

How to Remove Set-In Dog Urine from Nylon Carpet

For dried or old urine stains, the process is similar but may require more patience and a stronger approach.

1. Re-wet the area with cool water to help dissolve the dried urine. Blot to lift as much as possible.
2. Apply an enzymatic cleaner generously, ensuring it penetrates the fibers. You may need to work it in gently with a soft brush or cloth.
3. Cover with a damp cloth and place a weight on top (like a book) to keep the cleaner in contact with the stain. Let it sit for several hours or overnight.
4. Blot and rinse with cool water, then blot dry.
5. Repeat if necessary – set-in odors may require multiple treatments. If the smell persists after two or three attempts, consider professional cleaning.

What Not to Do

• Avoid steam cleaning right away, as heat can set the stain and odor.
• Do not use bleach or ammonia – these can damage nylon and may react with urine to create harmful fumes.
• Avoid rubbing the stain, as it can spread and push urine deeper.
• Do not use a regular carpet cleaner without checking that it is safe for nylon and effective on pet urine.
