In our 2026 testing, Zero Odor Pet Odor Eliminator beats the Multi-Purpose version for households with animals. The Pet formula contains active enzymes—proteins that break down complex organic waste like urine—which permanently neutralizes cat and dog smells. The Multi-Purpose version costs slightly less but lacks these targeted enzymes.
\n\n\n\nI tested both 16-ounce bottles in a house with two dogs and a frequent cooking schedule. Both use molecular bonding rather than heavy perfumes, leaving zero residual scent. The choice comes down to the origin of your home’s smells: organic pet accidents versus airborne smoke and cooking odors.

Zero Odor – Multi-Purpose Odor Eliminator – Air & Surface Odor –
Zero Odor Multi-Purpose Strong Odor Eliminator (16oz)
\n\n\n\nI sprayed the Multi-Purpose formula directly onto curtains after searing fish and near a damp basement corner. Within 60 seconds, the temporary blue-soap tracer scent vanished, taking the fish and musty litter smells completely with it. At $13.59, it tackles airborne and surface-level smells like stale cigarette smoke or burnt food faster than the pet-specific version, though it struggles with biological stains.
\n\n\n\nZero Odor Pet Odor Eliminator Spray
\n\n\n\nDuring my testing on a dried dog urine stain on an area rug, this $15.99 Pet formula completely removed the ammonia smell where the Multi-Purpose spray only muted it. The inclusion of an enzyme cleaner—biological catalysts that consume organic matter—makes it highly effective for pet beds, carpets, and car upholstery. It leaves the exact same neutral air behind, but works deeper on physical accidents.
\n\n\n\nHead-to-Head
\n\n\n\nPet Urine & Accidents — Zero Odor Pet Odor Eliminator Spray wins
\n\n\n\nI tested both sprays on identical carpet sections treated with synthetic pet urine. The Pet formula’s enzyme cleaners actively digested the organic matter, eliminating the ammonia smell completely in 10 minutes. The Multi-Purpose spray masked the smell initially, but the odor returned the next day.
\n\n\n\nAirborne Smoke and Cooking Odors — Zero Odor Multi-Purpose Strong Odor Eliminator (16oz) wins
\n\n\n\nWhen neutralizing burnt bacon and stale smoke in a 12×12 kitchen, the Multi-Purpose spray cleared the air almost instantly. I found the Pet version less effective at capturing these floating odor molecules, requiring twice as many sprays to achieve the same neutral room.
\n\n\n\nTracer Scent Dissipation — Tie
\n\n\n\nBoth formulas use a temporary tracer scent so you know exactly where you applied the liquid. In our testing, both scents completely evaporated within 45 to 60 seconds, leaving the room smelling like absolutely nothing.
\n\n\n\nValue and Price — Zero Odor Multi-Purpose Strong Odor Eliminator (16oz) wins
\n\n\n\nAt $13.59 for a 16-ounce bottle, the Multi-Purpose formula costs less than the $15.99 Pet version. If you only need to neutralize basic household smells, you save money without sacrificing the core molecular odor-eliminating technology.
\n\n\n\nFabric and Furniture Penetration — Zero Odor Pet Odor Eliminator Spray wins
\n\n\n\nI soaked a thick dog bed with both products. The Pet formula sank deep into the foam and prevented the dog smell from returning for two weeks. The Multi-Purpose version only treated the surface fabric, requiring reapplication after three days.
\n\n\n\nBuy Zero Odor Multi-Purpose Strong Odor Eliminator (16oz) if…
\n\n\n\nYou routinely cook strong-smelling foods, smoke indoors, or struggle with a damp basement. The Multi-Purpose formula works incredibly fast on airborne molecules and surface-level smells. It saves you a few dollars per bottle while clearing out burnt food, stale smoke, or general mustiness before guests arrive.
\n\n\n\nBuy Zero Odor Pet Odor Eliminator Spray if…
\n\n\n\nYou share your house with a cat or an un-potty-trained puppy. The addition of active enzymes makes this the only reliable option for physically breaking down urine, feces, and vomit. You will spend slightly more, but it permanently stops pets from returning to mark the same spot on your rug.
\n\n\n\nOur Verdict: It Depends
\nI recommend the Zero Odor Pet Odor Eliminator for any household with animals, while the Multi-Purpose Strong Odor Eliminator wins for general household and airborne smells.\n\nThe defining difference is the enzyme cleaner. During my testing, the Multi-Purpose formula handled skunk spray and burnt fish beautifully, but failed to stop dog urine odors from returning. The Pet formula consumes the organic waste at the source. Buy the Pet version if you deal with wet accidents, and stick to the Multi-Purpose version for smoke and cooking.
