How to Remove Pet Urine Odor From Carpet

Pet urine in carpet is a padding problem. The urine soaks through the pile into the padding beneath, and that’s where the smell lives. Surface cleaning reaches the pile; the padding keeps releasing the odor.

What causes it

Urine soaks through the carpet pile into the padding. The pile holds some residue, but the padding holds the bulk of it — and it’s enclosed, slow to dry, and keeps releasing odor.

Why it persists

The smell persists because the padding is hard to reach. A surface spray or a light treatment doesn’t penetrate to where the residue is. The padding keeps releasing odor, especially in humidity.

What actually helps

• Apply an enzymatic product generously — enough to reach the padding
• Let it work and dry fully
• Repeat for stubborn or old deposits
• For severe cases, address the padding directly

How to handle it

1. Blot any fresh urine
2. Apply an enzymatic treatment generously — enough to reach the padding
3. Let it work per the directions
4. Allow the carpet and padding to dry fully
5. Re-check in humid conditions — repeat if needed

Common mistakes

• A light spray that never reaches the padding
• Not letting the padding dry fully
• Giving up after one treatment on a deep deposit

When this approach may not work

If urine has soaked through to the subfloor, surface treatment may not reach it. Deep contamination can need professional extraction or pad replacement.

Where PawFresh fits

After the padding is treated and dry, the PawFresh NanoMist Fogger can freshen the carpet surface and ambient air — a fit for the residual odor.
