Key takeaways
  • Enzyme cleaners are designed to break down pet urine, vomit and feces odors, and humane societies recommend them for cleaning up accidents.
  • Blot first, rinse with cool water, then apply the cleaner per the label. Skip ammonia, vinegar and steam cleaners.
  • Reviews of popular cleaners praise results on old stains and tough odors. The common complaints are strong scents, repeat applications and a smell that may get worse before it gets better.
  • This guide is based on reading customer reviews and expert advice. We did not test the products ourselves.

Every pet owner eventually has to clean up an accident. The goal is to remove the smell completely, not only the stain, because the Humane World for Animals notes that pets are drawn back to places where they have gone before. This guide explains how to clean up and summarizes what customers say about five well-known cleaners.

How to Clean Up a Pet Accident

Humane World for Animals and the Nebraska Humane Society recommend the same basic steps for urine on carpet or upholstery:

  1. Blot. Soak up as much urine as possible with paper towels. The more you soak up, the easier the cleanup.
  2. Rinse the area with clear, cool water and blot or vacuum up the water.
  3. Apply an enzymatic cleaner and follow the label. Test a hidden area first for staining.
  4. Avoid ammonia, vinegar and steam cleaners. Strong chemical smells can encourage a pet to mark the spot again, and heat can set the stain and odor permanently.
  5. Let it dry. The ASPCA says most enzyme-based cleaners tend to cause mild stomach upset, so make sure the product has dried before pets go back into the area.

How We Picked These Cleaners

We looked at widely reviewed pet stain and odor cleaners on Amazon on October 22, 2026 and read the customer reviews on each product page. We paraphrase what buyers report and we did not test any product ourselves. Ratings on cleaners are more mixed than for many products, because results depend on the surface, the age of the stain and how much you use, so we have been careful to include complaints too.

The Cleaners

Nature's Miracle Stain and Odor Remover (32 oz) Most popular all-rounder

Reviewers use it on rugs, a couch, a mattress and for puppy and elderly-dog accidents. Several say to clean up what you can first, then saturate the spot and let it sit. A few say it saved furniture after pet or even human messes. Reviewers with large or incontinent dogs say they went through a lot of it, so factor in volume if you have frequent accidents.

FurryFreshness Extra Strength Pet Urine Eliminator Best for old, set-in stains

Reviewers with long-standing urine problems say it pulled odor out of carpet padding and worked on vinyl plank. Several warn that the area can smell stronger for a few days before the odor disappears, and some need two or three applications. A few reviewers say it works on some stains and not others, so it is not a guaranteed fix.

ANGRY ORANGE Pet Odor Eliminator and Stain Remover (2-pack) Strong-odor pick

Buyers dealing with cat spraying and old pet smells say it was the first product that removed the odor. The most frequent complaint is a very strong citrus scent. One reviewer needed several sprays, and two reviewers said it did not stop their dogs from marking.

Begley’s Pet Stain and Odor Remover Natural-scent pick

Reviewers like the pleasant scent and use it on beds, mattresses, couches and crates. Some complain that the formula changed after a change of ownership or that the new spray nozzle failed within days, so check the nozzle when it arrives.

PetSafe Wee Care Pet Loo Enzyme Cleaner For fake grass and potty trays

Reviewers who use artificial turf or the PetSafe Pet Loo say a heavy spray and a few minutes of soaking rinsed urine odor out. One reviewer said it did not remove the plastic smell of the grass itself, and another received a bottle without a sprayer. It is made for those setups and is less clearly aimed at carpet.

Tips From the Experts

  • Find hidden spots. A black light can show old urine stains. Outline them with chalk.
  • If you used another cleaner first, the Nebraska Humane Society says enzymatic cleaners break down the old cleaner but not the urine, so rinse well first.
  • Do not cover the smell with fragrance. From your pet’s point of view, it is the scent that matters. As long as your pet can smell their own scent, they may return.
  • Retrain. Take your dog out often and reward success. See our guide to potty training a puppy.
  • See your vet for repeated accidents. Humane World for Animals says a pet that has regular accidents should be checked by a veterinarian to rule out medical causes.

Frequently Asked Questions

Do enzyme cleaners really work?

Humane societies recommend them for breaking down pet waste odors. Reviews suggest results vary with the surface, the age of the stain and how thoroughly you saturate it.

Can I use vinegar or ammonia?

Humane World for Animals and the Nebraska Humane Society advise avoiding both, because strong smells may encourage the pet to mark the spot again.

Is it safe around my pet?

The ASPCA says most enzyme-based cleaners cause only mild stomach upset if swallowed, so keep your pet away until the area dries. If you think your pet swallowed a cleaner, call your vet or a poison control center.

Why does my pet keep going in the same spot?

Lingering scent is a common reason. Clean thoroughly and see your vet if accidents continue.
