Waldo;
We mix our Odor Attack (percarbonate + compatible actual enzyme)
in a container that can dispense fairly large amounts of liquid on the stains.
Some use pressurized SS canisters, 5 gal pails, or plant watering containers.
The thing you have to remember is to apply the same amount of liquid that was deposited by the animal in the first place.
Only then will it reach to the level of the original stain.
Finally, extract with a flash-extractor spotting claw
and then rinse with a hand gun spraying solution around the edges of the claw.
