Review · Earthworm

Earthworm Pet Stain & Odor Eliminator

The clear winner of the enzyme cleaners we synthesized — ahead of Nature's Miracle and far ahead of Bissell. Earthworm's 100% enzyme formula removed fresh and set-in stains, eliminated the microscopic scent markers that trigger repeat marking, and did it with a short, non-toxic, plant-based ingredient list and only a mild natural citrus scent.
