How to get rid of pet urine smell

The Casaloop teamUpdated

Quick answer

Blot up as much urine as you can with paper towels, without scrubbing. Rinse with cool water and blot again. Then apply an enzymatic cleaner made for pet urine, following the label, and let it sit and air dry. Skip steam cleaners and hot water, which set the smell, and strong-smelling cleaners like ammonia or vinegar, which can draw your pet back.

To get rid of pet urine smell, blot up as much as you can without scrubbing, rinse with cool water, blot again, then treat the spot with an enzymatic cleaner made for pet urine, following the label. Enzymes break down what causes the smell instead of covering it up. And avoid steam, hot water and strong-smelling cleaners, which either lock the smell in or invite a repeat visit.

One thing to know before you start: your nose gives up on the smell long before your pet’s does. If they can still smell it, they’ll come back to it. So the goal is removing the urine, not perfuming over it.

Step by step for a fresh accident

  1. Blot, don’t scrub. Lay down a thick stack of paper towels or an old towel and press. On carpet or a couch, stand or lean on it, swapping in fresh towels until they come up barely damp. Scrubbing spreads the pee and pushes it deeper.
  2. Rinse with cool water. A little cool water on the spot, then blot again. Never hot.
  3. Apply the enzymatic cleaner generously enough to reach wherever the urine went. On thick fabric or carpet, that means soaking, not misting.
  4. Leave it for the full dwell time on the label. Enzymes work slowly.
  5. Let it air dry. Cover it with a clean towel or a laundry basket if your pet is curious.
  6. Sniff it the next day, up close. If you can still smell it, treat it again.

Spot-test somewhere hidden first, especially on colored fabric, leather and wood.

What to avoid (even if it seems like a good idea)

Humane World for Animals flags three traps:

  • Steam cleaners and hot water. Heat sets both the stain and the odor, especially in synthetic fibers. Keep the steam cleaner well away.
  • Ammonia and vinegar. Strong smells don’t remove the urine odor and may encourage your pet to re-mark the spot.
  • Layering products. Besides interfering with the enzymes, mixing cleaners can be dangerous. The CDC is clear: never mix bleach with ammonia or any other cleaner. One product at a time, with a rinse in between.

There’s more on risky combinations in cleaning products you should never mix.

Surface by surface

Where What to do
Tile and stone floors Blot, wipe with water, then enzymes. Watch the grout, which soaks things up
Hardwood and laminate Blot fast. Urine can discolor wood and react with the finish; a stained patch may need refinishing
Carpet and rugs Blot under pressure, rinse, then plenty of enzyme cleaner. If it reached the pad, that section may need replacing
Couch Blot under pressure, enzymes deep enough to reach the cushion. Spot-test the fabric first
Mattress Same as the couch, with a long drying time. See how to clean a mattress
Clothes, bedding and throws Wash as usual with some baking soda added. If the smell lingers, wash again with an enzymatic cleaner. Air dry

Old stains: first, find them

Dried pee is the worst kind because you don’t always know where it is. A few ways to track it down:

  • A black light (UV flashlight) shows old stains you can’t see in normal light. Turn the lights off, sweep it slowly near the floor, and outline what you find with chalk or painter’s tape.
  • Your nose, close to the floor, in your pet’s favorite corners.
  • Baseboards and furniture legs, the classic targets for a dog that’s marking.

Found it? Same process, with more patience: let the enzyme cleaner work longer and repeat if needed. If you’ve already tried other products on that spot, rinse it well with water and let it dry before the enzymes go on, so one doesn’t cancel out the other.

Build an accident kit

Fresh pee comes out far more easily than yesterday’s pee. Keep everything in one place so you’re not hunting under the sink while it soaks in:

  • a roll of paper towels or a stack of old rags;
  • a bottle of enzymatic cleaner, already opened, label facing out;
  • a spray bottle of plain water for rinsing;
  • gloves;
  • a bag for the used towels;
  • a UV flashlight for the spots you missed.

Keep it in a bucket in the laundry room or a closet, out of your pet’s reach. When it happens, grab the bucket and run the steps above. Speed matters more than technique.

When it’s a job for the vet

If accidents have become a pattern, start with the vet, not the carpet cleaner. Humane World recommends having a vet check for medical causes when a pet has regular accidents. For cats, the ASPCA advises that a cat urinating outside the litter box be examined for an underlying medical condition before it’s treated as a behavior problem.

In the meantime, keep cleaning promptly so the spot doesn’t become a habit. For the rest of the house, how to keep a clean house with pets helps you build a routine around them.

Frequently asked questions

Does baking soda and vinegar get rid of pee smell?

It's the most famous home remedy, but it isn't what animal welfare groups recommend. Humane World for Animals advises against strong-smelling products like vinegar and ammonia, since they don't remove the urine odor and may encourage your pet to mark the same spot again. Their pick is an enzymatic cleaner.

Where do I find an enzymatic cleaner?

Pet stores, big-box stores and online, usually in the cleaning or pet aisle. Look for a label that says it's for pet urine and mentions enzymes. Check the dwell time and whether it's safe for your floor or fabric before you buy.

Why does the smell come back on humid days?

Because some urine is still in the material, often deeper than you cleaned: in the couch cushion, the carpet pad or the grout. Humidity reactivates it. Treat the spot again, using enough enzymatic cleaner to soak as deep as the urine did.

Should I keep my dog or cat out of the house until they stop?

That doesn't address the cause and can make things worse. Start with the vet to rule out a medical problem, then work on the behavior side with professional help, like a trainer or a certified animal behaviorist.

Can I use bleach on pet urine?

Bleach doesn't break down urine the way enzymes do, and it shouldn't be combined with other cleaners: the CDC says never mix bleach with ammonia or any other cleaner. If you do use it on a surface, use it alone, as the label directs, rinse well and keep pets out until dry.
