Key takeaway
Enzymes are matched to the residue — proteases for protein, lipases for oil, amylases for starch.
Enzymes are the active ingredient in a growing class of cleaning products — biological catalysts that break down specific residues. Each type targets a different kind of organic soil.
What causes it
Enzymes are proteins that speed up specific chemical reactions. In cleaning, they’re matched to the residue: proteases break down protein-based deposits (like urine and biological soils), lipases break down oils and fats, amylases break down starches. The enzyme acts on its specific substrate, breaking it into smaller compounds.
Why it persists
The reason enzymes are effective is specificity — a protease only acts on protein, so it goes after the urine residue and leaves the surface alone. The residue is broken into smaller compounds that are easier to remove and less odorous.
What actually helps
- Match the enzyme to the residue
- Give it contact time
- Let the area dry fully
- For mixed residues, a blend covers more
| Enzyme | Targets | Common in pet odor |
|---|---|---|
| Protease | Protein-based residue | Urine, biological soils |
| Lipase | Oils and fats | Skin oils, sebum |
| Amylase | Starches | Food residue, some soils |
Where PawFresh fits
The PawFresh ActiveEnzyme Formula is an enzyme-based blend designed to act on the range of organic residues that carry pet odor.

Frequently asked questions
What are enzymes in cleaning products?
Biological catalysts that break down specific residues — proteases for protein, lipases for oil, amylases for starch.
What does a protease enzyme do?
Breaks down protein-based residue — like urine and biological soils.
Why are enzymes effective cleaners?
They are specific — each enzyme acts on its residue, breaking it into smaller, less odorous compounds.
