Updated 2026-05-19
Nature's Miracle, Rocco & Roxie, Anti-Icky-Poo, Skout's Honor, and BISSELL — compared on dog urine, cat urine, and vomit. Stain removal, odor neutralization, re-marking prevention.
Quick answer
Anti-Icky-Poo Unscented is the professional choice and the only cleaner here that fully eliminated 7-day-old cat urine, with double-strength enzyme and no fragrance — so you can actually tell when a spot is clean rather than masked. Nature's Miracle is the established standard, vet-recommended for 40+ years and widely stocked; buy the Advanced formula, which eliminated over 90% of 24-hour-old cat urine. Rocco & Roxie performs comparably to Nature's Miracle Advanced with a milder scent.

Enzyme cleaners vs. bleach/ammonia
Enzyme cleaners break down proteins in urine/vomit/feces at molecular level — waste converts to CO2 and water, nothing left to detect.
Bleach masks odors but doesn't break them down — pets re-mark. Ammonia is actively worse: cat urine contains ammonia, so ammonia cleaners trigger re-marking.
Vinegar works as budget enzyme for fresh stains but doesn't break down set-in stains.
Cat urine — hardest test
Cat urine is hardest due to urea, creatinine, and felinine (cat-specific sulfur amino acid that breaks down over time releasing the 'old cat urine' smell).
Anti-Icky-Poo was the only one that fully eliminated 24-hour-old cat urine; Nature's Miracle Advanced came closest, removing over 90%. Others left detectable residue on set-in stains.
