How Enzymatic Cleaning Works

Enzymatic cleaning is the approach that actually addresses the source of pet odor — not by covering the smell, but by breaking down the residue producing it. Understanding how it works explains why it lasts.

What causes it

Enzymes are biological catalysts — proteins that speed up specific chemical reactions. In cleaning, they’re matched to the residue: protease enzymes target protein-based deposits, lipases target oils, amylases target starches. Each enzyme acts on a specific kind of residue, breaking it into smaller compounds that are easier to remove and less odorous.

Why it persists

The reason enzymatic cleaning lasts is that it removes the source, not just the symptom. The residue that was releasing odor is broken down — there’s less left to keep producing the smell. This is the difference between addressing the cause and covering it.

What actually helps

• Use an enzymatic product for organic odor
• Give it time — enzymes need contact time to work
• Let the area dry fully
• Repeat for stubborn residue

How to handle it

1. Identify the residue type — urine, oils, organic
2. Apply an enzymatic product to the area
3. Let it work — enzymes need contact time
4. Allow the area to dry fully
5. Re-check and repeat for stubborn residue

Common mistakes

• Wiping the product off too soon — enzymes need time
• Using an enzymatic product on a non-organic odor
• Not letting the area dry fully

Where PawFresh fits

The PawFresh ActiveEnzyme Formula is built on this principle — an enzyme-based blend designed to act on the organic residues that carry pet odor.
