How To Clean Cat Pee Out Of Mattress: Step‑by‑Step FAQ Guide
If you’re searching for “How To Clean Cat Pee Out Of Mattress”, you’re likely dealing with a fresh accident or a lingering smell. This guide walks through what to do right away, how to tackle old stains, and how to prevent odors from coming back.
What should I do first when my cat pees on the mattress?
Acting quickly makes a big difference.
Remove bedding immediately
Take off sheets, mattress protectors, and blankets and treat them separately in the wash.Blot, don’t rub
Use clean, absorbent towels or paper towels and press firmly to soak up as much urine as possible.- Avoid rubbing, which can push urine deeper into the mattress.
Mark the affected area
Once it’s mostly blotted, mentally note or lightly mark the area so you can treat the full spot.
How To Clean Cat Pee Out Of Mattress: What cleaning solution works best?
Cat urine is tricky because of its strong odor and tendency to linger. The general approach is:
Step 1: Apply an enzyme-based cleaner (if available)
Enzymatic cleaners are commonly used on organic stains like urine because they help break down odor-causing components.
- Saturate the area where the cat peed, reaching slightly beyond the visible spot.
- Let it sit for at least 10–15 minutes, or longer if the product suggests.
- Blot again with clean towels to remove excess moisture.
Step 2: Use a mild vinegar solution if you don’t have enzyme cleaner
Mix equal parts white vinegar and water in a spray bottle or bowl.
- Lightly soak the stained area (but don’t drench the whole mattress if you can avoid it).
- Vinegar helps neutralize odors and break down urine.
- Let it sit for 10–20 minutes, then blot well.
Step 3: Deodorize with baking soda
Once you’ve blotted thoroughly, sprinkle a generous layer of baking soda over the damp area.
- Leave it on for several hours, ideally overnight, to absorb moisture and odor.
- Vacuum slowly and thoroughly to remove all baking soda before making the bed again.
How do I deal with dried or old cat pee stains?
Old stains can be harder to find and treat, but they can still improve.
How can I find old urine spots?
- Look for discolored patches or slight yellowing.
- Smell around the mattress surface; odors are usually strongest in the center of the stain.
How do I treat set-in stains?
- Lightly dampen the area with plain water to rehydrate the stain.
- Apply an enzyme cleaner or vinegar solution as described above.
- Let it sit longer than for a fresh stain—often 20–30 minutes.
- Blot thoroughly and then use baking soda and vacuum after it dries.
Repeated treatments may be needed for stubborn odors and older stains.
Can I use bleach or harsh chemicals on my mattress?
In most cases, bleach and strong chemicals aren’t recommended on mattresses because they can:
- Damage mattress materials
- Leave strong, lingering chemical odors
- Discolor fabrics
Milder options like water, white vinegar, and baking soda, or specialized urine stain removers, are usually enough for most household situations.
How long will it take for my mattress to dry?
Drying time depends on how much liquid soaked in and the room conditions.
To help it dry faster and more completely:
- Open windows or use a fan to improve air circulation
- If possible, stand the mattress upright so both sides get some airflow
- Avoid making the bed until the area is completely dry to the touch
Rushing to cover a damp mattress can trap moisture and make odor problems worse.
What if the smell is still there after cleaning?
If there is still a noticeable odor:
- Repeat the enzyme treatment on the same area
- Give the mattress extra time to dry between treatments
- Use additional baking soda and vacuum again
Severe or repeated accidents may leave a lingering scent even after several cleanings. In those cases, more intensive deep cleaning methods or professional help may be considered.
How can I prevent future cat pee accidents on my mattress?

- Use a waterproof mattress protector as a barrier against future accidents
- Keep the litter box clean and accessible
- Watch for behavioral changes in your cat and adjust environment or routine as needed
