How To Remove Pet Urine From Your Car Interior

How to clean pet urine off car seat - auto detailing service

Pet owners all share the frustration of dealing with something inevitable – the foul smell of pet urine inside the car. But that’s just a small price to pay for taking your pets on road trips and adventures. Instead of denying them car rides to avoid smelly car seats, learn how to remove pet urine from your car interior with our help!

If you’ve read our previous blogs on how to remove coffee and vomit stains, you’d know by now that any organic stain, like pet urine, can be removed by applying the CHAT method. This method also helps take the urine smell out of car upholstery.

It’s important to get rid of the entire stain so the smell doesn’t linger. Once neglected, old and dried urine stains can be challenging to remove but still doable.

Remember: Always wear protective gear such as a mask, gloves, and eyewear because it’s a biohazard stain.

Remove Pet Urine From Your Car

If you’re a long-time pet owner, you must be used to cleaning your pet’s urine on the floor all the time. After all, it’s just a simple wipe-and-mop situation. But when your cat or dog pees on your car interior, that’s a whole different story. You’re going to need a more effective cleaning method than just wiping and mopping. The good news is that removing pet urine stains is something you can do on your own, it’s not rocket science!

The four main chemicals you need in order to remove pet urine stains and neutralize the smell are:

  • Baking soda
  • Vinegar
  • Hydrogen peroxide
  • Dishwashing liquid

Here’s a step-by-step process for removing pet urine from your car interior.

Step 1 -

Blot and mop the excess urine stain. It’s best if you deal with the urine right away rather than leaving it for a few days to dry on the car seat or carpet. If that’s the case, don’t worry because we will tell you how to remove old and dried pet urine stains from your carpet at the end of this post.

Remove Old and Dried Pet Urine Stains from Your Car

If you did not deal with the urine stain on your car interior right away as it happened, it’s okay. There’s still a way to remove the stain even though it has dried on your car carpet. However, old pet urine stains can be more difficult to remove because the stain could have already set on the fibers of your car interior.

The best way to deal with this is to soften the fabric using a steam cleaner and scrub with a drill brush. Remember to use the CHAT method mentioned earlier. Using the right chemical solution aided with a steam cleaner, repetitive agitation via drill brush, and the dwelling time of the chemicals, the old dried stain should be removed.

However, if you don’t have any of these tools, we recommend hiring a professional mobile car detailer like River Islands Car Salon. An expert car detailer has special chemicals with enzyme stain removers and a carpet extractor to deal with stubborn pet urine stains.

You can apply and follow the previous steps above and see if it helps. This way, you’re removing the excess smell and stains. You can let the professional detailers handle the rest of it to remove it completely.


To refresh your memory, remove pet urine smells and stains from your car interior by blotting the excess with paper towels or old microfiber towels. Next, spray the area with hot water and a few drops of dishwashing soap in the scrub. 

Then mop the area and spread a few ounces of baking soda into the affected area. Let it dwell for 15 to 30 minutes and spray some diluted vinegar. Finally, scrub and wipe the excess and spray diluted hydrogen peroxide to disinfect.

Baking soda, vinegar, hydrogen peroxide, and dishwashing liquid are the best chemicals for removing pet urine stains. Just apply the CHAT method correctly and you’ll be removing stains like a pro in no time.

Now that you know how to remove pet urine smells and stains from your car interior, make sure to apply the process when the need arises.
