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 and Nature's Miracle Advanced were the only two that fully eliminated 24-hour-old cat urine. Others left detectable residue on set-in stains.
