How to Clean Up a Pet Accident

Clean up a pet accident properly — blot, treat the residue, dry fully — and avoid the mistakes that leave the smell behind.

In short

Clean up a pet accident by blotting (not rubbing) the liquid immediately, treating the area with an enzymatic product that reaches the residue, and letting it dry fully. The key is treating the residue, not just the surface.

Key takeaway

Blot, treat the residue, dry fully. The residue is what leaves the smell — treat it, don’t just wipe it.

A pet accident handled wrong leaves a smell that lasts for months. Handled right, it’s a non-event. The difference is treating the residue, not just wiping the surface.

What causes it

An accident leaves two problems: the visible liquid and the residue it leaves behind. Blotting removes the liquid; the residue — uric acid and organic compounds — soaks into the surface and padding and keeps releasing odor.

Why it persists

The smell persists if you stop at the surface. Rubbing spreads the residue. Wiping without treating leaves it to soak deeper. The residue is what smells — so that’s what you have to treat.

What actually helps

  • Blot, don’t rub — rubbing spreads the residue
  • Treat with an enzymatic product that reaches the residue
  • Let it dry fully — damp material holds odor
  • Repeat for old or deep accidents

How to handle it

  1. Blot the liquid immediately — press, don’t rub
  2. Apply an enzymatic treatment generously to reach the residue
  3. Let it sit per the product directions
  4. Blot again and let it dry fully
  5. Re-check — repeat if the odor returns

Common mistakes

  • Rubbing the accident — that spreads the residue
  • Only wiping the surface while the residue soaks deeper
  • Not letting the area dry fully
  • Using a regular cleaner that doesn’t act on the residue

Where PawFresh fits

For the ambient odor after an accident is cleaned, the PawFresh NanoMist Fogger spreads the ActiveEnzyme Formula as a fine mist — a fit for the room’s residual smell.

Frequently asked questions

How do I clean up a pet accident?

Blot the liquid, treat the area with an enzymatic product to reach the residue, and let it dry fully.

Should I blot or rub a pet accident?

Blot — pressing lifts the liquid; rubbing spreads the residue deeper into the surface.

Why does a cleaned accident still smell?

The residue soaked deeper than the surface clean reached — treat it with an enzymatic product.
