Struggling to get urine stains out of your mattress? Whether it comes from a child, a pet, or an unexpected accident, urine can be frustrating. The longer it sits, the deeper it soaks into the fabric and foam, creating unpleasant stains and lingering odors. There is no need to throw away your mattress or spend money on expensive cleaning services.
Instead, read this guide that explains how to get pee out of a mattress quickly and effectively using simple household items. If you follow the right steps, you can remove stains, eliminate odors, and keep your mattress fresh and clean.
Why Urine Is Difficult to Remove from a Mattress
Unlike spills that stay on the surface, urine penetrates deep into mattress layers. As it dries, it leaves behind uric acid crystals that continue producing odors. This is why it may still smell bad even after the stain appears to be gone.
The key to successful cleaning is treating both the visible stain and the odor-causing residue hidden inside the mattress.
What You Need Before You Start
Gather these supplies before cleaning:
- Clean towels or paper towels
- Cold water
- White vinegar
- Baking soda
- Spray bottle
- Vacuum cleaner
- Mild laundry detergent (optional)
- Hydrogen peroxide (for stubborn stains)
Using these common household products can help remove both fresh and old urine stains.
How to Get Fresh Pee Out of a Mattress
Step 1: Blot the Area Immediately
- As soon as you notice the accident, use dry towels or paper towels to absorb as much urine as possible.
- Press firmly on the affected area without rubbing. Rubbing can push the urine deeper into the mattress fibers.
- Continue blotting until the towels no longer absorb moisture.
Step 2: Apply a Vinegar Solution
- Mix equal parts white vinegar and cold water in a spray bottle.
- Lightly spray the stained area until it is damp but not soaked. Vinegar helps neutralize urine odors and break down residue.
- Allow the solution to sit for 10 to 15 minutes.
Step 3: Blot Again
- Use fresh towels to absorb excess moisture from the mattress.
- Repeat until most of the liquid has been removed.
Step 4: Cover with Baking Soda
- Sprinkle a generous amount of baking soda over the entire affected area.
- Baking soda naturally absorbs moisture and odors while helping lift remaining urine residue.
- Leave it on the mattress for at least 8 hours or overnight for best results.
Step 5: Vacuum the Mattress
- Once the baking soda is completely dry, vacuum it thoroughly.
- Your mattress should now smell significantly fresher and show little to no staining.
How to Remove Dried Urine Stains from a Mattress
Old urine stains require a stronger cleaning approach because the urine has already dried and bonded with the mattress material.
- Create a Deep-Cleaning Solution and mix 8 ounces of hydrogen peroxide, 3 tablespoons of baking soda, and a few drops of mild dish soap.
- Stir gently until combined.
- Pour the mixture into a spray bottle and lightly spray the stained area.
Let the Solution Work
- Allow the cleaner to sit for 30 to 60 minutes.
- You may notice bubbling as the solution breaks down stain particles and odor-causing compounds.
Dry and Vacuum
- Let the mattress air dry completely.
- Once dry, vacuum away any remaining residue.
- This method often removes stubborn yellow urine stains that regular cleaning cannot eliminate. Now, do you know how to get stains out of a mattress?
How to Remove Pet Urine Odor from a Mattress
- Pet urine can be particularly challenging because it contains concentrated compounds that produce strong odors.
- After cleaning with vinegar and baking soda, consider using an enzyme cleaner specifically designed for pet accidents.
- Enzyme cleaners break down urine proteins at the molecular level, eliminating odors instead of simply masking them.
- Always follow the manufacturer’s instructions when using enzyme-based products.
Tips to Prevent Mattress Damage
Proper cleaning is important, but prevention is even better. Consider these tips:
- Use a waterproof mattress protector.
- Clean accidents immediately.
- Wash bedding regularly.
- Allow the mattress to air out occasionally.
- Keep pets off the bed if accidents are common.
- A quality mattress topper can save hundreds of dollars in potential replacement costs.
Common Mistakes to Avoid
- Using Hot Water: Hot water can set urine stains permanently into mattress fibers. Always use cold water during cleaning.
- Oversaturating the Mattress: Too much liquid can lead to mold or mildew growth inside the mattress. Use only enough cleaning solution to dampen the area.
- Skipping Drying Time: A damp mattress can develop unpleasant odors and bacteria. Always allow it to dry completely before replacing bedding.
- Ignoring Old Stains: Even if a stain appears small, untreated urine residue can continue producing odors over time.
When to Replace a Mattress
Most urine stains can be removed successfully. However, replacement may be necessary if:
- The mattress has multiple deep stains.
- Strong odors remain after repeated cleaning.
- Mold or mildew has developed.
- It is already old and worn out.
In these cases, investing in a new model may be the healthier option. But, how often should you change your mattress?
Conclusion: Keep Your Mattress Fresh
Getting pee out of a mattress is easier than many people think. Quick action, proper cleaning techniques, and common household products can remove most stains and odors effectively. For fresh accidents, blotting, vinegar, and baking soda usually do the trick. For older stains, hydrogen peroxide solutions can provide deeper cleaning. With consistent care and preventive measures such as mattress toppers, you can keep your mattress clean, odor-free, and comfortable for years to come.

For best results, leave baking soda for at least 8 hours or overnight before vacuuming.
- Does hydrogen peroxide remove urine stains?
Yes. Hydrogen peroxide can effectively break down old urine stains and reduce discoloration. Always test a small hidden area first to ensure it does not affect the fabric.
- Can old urine stains be removed from a mattress?
Yes. Although older stains are more difficult to remove, a combination of hydrogen peroxide, baking soda, and mild dish soap can often eliminate both stains and odors.
