How to Remove Pet Urine Smell from Carpet

By Mr Expert Carpet Cleaning, Slough · Updated 7 October 2026

Blot fresh urine straight away with kitchen paper, do not rub, and do not use steam or heat on a fresh stain. For old stains and a smell that keeps coming back, professional treatment is the reliable fix. Our pet urine and severe odour treatment starts from £85.

What to do straight away

1. Blot with kitchen paper or a clean cloth, pressing down to soak up as much as you can. Do not rub, because rubbing pushes it deeper.
2. Keep replacing the paper until it comes up almost dry.
3. Use a cleaner made for pet urine and follow the label. Test on a hidden patch of carpet first.
4. Blot again and let the area dry with the window open.

What to avoid

• Do not use hot water or steam on a fresh stain. Heat can make it harder to remove.
• Do not mix cleaning products. Some combinations give off harmful fumes.
• Do not soak the carpet. Extra water carries urine further down.

Why the smell comes back

Urine can soak through the carpet into the backing and underlay. A surface clean removes what you can see, but whatever is deeper can smell again, especially when the air is damp. That is why old or repeated accidents usually need a deeper treatment.

When to call a professional

• The smell returns after you have cleaned it.
• The patch is large or old, or you are not sure where it is.
• More than one area has been affected, or the urine has reached the underlay.
