Still not working?Common mistakes. Trusting "natural" or "organic": the label should specifically say 'enzymatic' or 'bio-enzymatic.' Vague terms don't mean the product contains the right enzymes.
In this guide
The pet aisle is full of bottles that promise to erase odor, and most do nothing about urine. They cover the smell. Enzymes break it down.
Short answer: For dog pee, buy an enzyme cleaner. Look for "enzymatic" on the bottle, soak the spot, and start with Naturally It's Clean.
Why it works: Enzymes break the pee down, soap only lifts what's on the surface. The catch: enzymes need a longer soak than spray-and-wipe. Naturally It's Clean takes a few minutes on a fresh spot; Rocco & Roxie wants overnight on an old one.
Why regular cleaners lose to dog pee
How regular cleaners work (and why they fail)
Traditional cleaners use one of two approaches:
Surfactants lift dirt and grime (but can't break down uric acid)
Key takeaways
Regular cleaners mask odor. Enzymes break it down
Enzymes break down uric acid crystals that cause lingering smell
Let enzyme cleaners air dry for best results
Store enzyme products at room temperature
Fragrances mask odors (temporarily)
Some use oxidizers that can bleach fabrics
None of these break down the source of urine odor
How enzyme cleaners work
Enzyme cleaners take a completely different approach. They contain beneficial bacteria that produce enzymes that break down organic matter:
Protease enzymes break down proteins
Amylase enzymes break down starches
Lipase enzymes break down fats
Uricase enzymes specifically target uric acid
The bacteria break the urine down so there is less left to smell.
What to look for when buying
1. Bio-enzymatic or enzymatic formula
The label should specifically say 'enzymatic' or 'bio-enzymatic.' Vague terms like 'natural' or 'organic' don't mean the product contains the right enzymes.
2. No artificial fragrances
Fragrance doesn't help. It just covers up what's still there. Plus, some dogs are drawn to new scents and mark over them. Look for 'unscented' or 'fragrance-free.'
3. Safe for your specific surfaces
Not all enzyme cleaners are safe for all surfaces. Check that your cleaner is approved for:
Carpets and rugs
Hardwood (if applicable)
Upholstery and furniture
Pet bedding and fabrics
4. Pet and child safe
Look for products that are safe once dry. Avoid cleaners with:
Chlorine or bleach
Ammonia (smells like urine to dogs)
Phenols (toxic to pets)
Isopropyl alcohol in high concentrations
5. Concentrated vs. Ready-to-Use
Concentrates cover more messes per bottle, but ready-to-use is more convenient. Consider how often you'll need it.
What a bottle really covers
A cleaner only earns its place if it works.
What actually changes how many messes a bottle covers:
Ready-to-use sprays: Easiest on a fresh spot, but one big soak can drain a bottle
Concentrates: You mix them yourself, so one bottle covers more messes
Bottle size: An old stain needs enough cleaner to reach the pad, so buy for the size of your mess, not the label hype
The enzyme cleaners we favor
Best overall: Naturally It's Clean. Enzymes the maker calls plant-based, and the maker says no artificial fragrances. Made for carpet and upholstery. Great for everyday accidents.
Best for laundry: ACTIVE Enzyme Laundry Booster. Bio-active enzymes in an unscented powder you add to your normal detergent, to go after the odor and the sweat, oil and blood stains in pet bedding and blankets. 64 loads in the 2 lb tub. See the Enzyme Laundry Booster on Amazon
Common mistakes
Skip these
Trusting "natural" or "organic": the label should specifically say 'enzymatic' or 'bio-enzymatic.' Vague terms don't mean the product contains the right enzymes.
Reaching for vinegar: it knocks back some odors, but it can't break down uric acid crystals, and it smells enough like urine that some dogs will mark over it.
Relying on baking soda: it can absorb surface odors, but it can't penetrate carpet fibers or padding where urine soaks in.
Steaming first: heat can set protein-based stains and spread the affected area. Always use enzyme cleaner first.
Cleaners with the wrong ingredients: avoid chlorine or bleach, ammonia (smells like urine to dogs), phenols and isopropyl alcohol in high concentrations.
The Bottom Line
In short
If you're dealing with dog urine, enzyme cleaners are the tool to reach for. Regular cleaners lift what sits on the surface; they are not made to break down the source of the odor.
Our top pick is Naturally It's Clean: it works and it's plant-based.
