Dog accidents on the mattress are super common — especially with puppies or older dogs. The good news? You can clean it effectively and get rid of both the stain and the smell if you act quickly and use the right method.
In this easy guide, you’ll learn exactly how to clean dog pee from a mattress using simple household items or an enzyme cleaner. Follow these steps and your mattress can look and smell fresh again.
What You’ll Need
- Paper towels or clean white cloths
- Spray bottle
- Distilled white vinegar
- Baking soda
- Mild dish soap (optional)
- Enzyme cleaner made for pet urine (highly recommended)
- Vacuum cleaner
- Fan or hair dryer (for faster drying)
Step-by-Step: How to Clean Fresh Dog Pee
- Remove bedding immediately Strip the bed and wash all sheets, blankets, and mattress protector in hot water.
- Blot, don’t rub Use paper towels or clean cloths to press down and absorb as much urine as possible. Replace towels until they come away mostly dry.
-
Apply a cleaning solution
- Best option: Use an enzyme cleaner designed for pet urine. Spray it generously on the spot and let it soak for 10–15 minutes (or follow the bottle instructions).
-
DIY option: Mix equal parts cold water and white vinegar in a spray bottle. Spray the area thoroughly.
- Blot again Use fresh towels to soak up the solution and remaining urine.
- Deodorize with baking soda Sprinkle a generous layer of baking soda over the damp area. Let it sit for at least 8–12 hours (or overnight).
- Vacuum thoroughly Vacuum up all the baking soda.
- Dry completely Let the mattress air dry for several hours. Use a fan or dehumidifier to speed it up. Never put sheets back on until the mattress is 100% dry.
How to Clean Dried or Old Dog Pee Stains
For older accidents where the pee has dried:
- Vacuum the area first to remove any loose debris.
- Spray the spot heavily with an enzyme cleaner or vinegar solution.
- Let it sit for 15–30 minutes so it can break down the dried urine crystals.
- Blot with clean towels.
- Repeat the baking soda step (sprinkle, wait overnight, vacuum).
- If the smell remains, repeat the enzyme cleaner treatment.
Extra Tips for Better Results
- Act fast — The sooner you clean it, the easier it is to remove the smell.
- Enzyme cleaners are worth it — They break down the proteins in urine that cause the strong smell. Regular cleaners often leave the odor behind.
- Test in a small area first — Especially on colored or memory foam mattresses.
- Prevent mold — Make sure the mattress is completely dry before putting sheets back on.
- Protect your mattress — Use a waterproof mattress protector in the future. It saves a lot of hassle.
How to Prevent Future Accidents
- Take your dog out more frequently (especially puppies).
- Use crate training when you can’t supervise.
- Consider a waterproof mattress protector or dog bed cover.
- For senior dogs or dogs with medical issues, talk to your vet.
