Accidents happen—whether it’s your child, pet, or a leaky bladder. If you're dealing with urine stains on a mattress or fighting that lingering pee smell, don’t panic. You can remove fresh or dried pee using simple household items like hydrogen peroxide, baking soda, and white vinegar. Here’s how to clean a mattress and eliminate urine odors for good.
🚫 How to Remove Dried Urine Stains from a Mattress
Best for: Set-in pee stains or old urine smells.
What you’ll need: Hydrogen peroxide, baking soda, dish soap, white cloths, vacuum.
1. Mix a cleaning solution
In a bowl or spray bottle, combine:
-
8 oz hydrogen peroxide (3%)
-
3 tbsp baking soda
-
A few drops of liquid dish soap
Use the mixture immediately for best results.
⚠️ Do a spot test first—hydrogen peroxide can lighten some fabrics.
2. Dab the stain
Apply the solution to a clean white cloth and gently blot the stain. Don’t soak the mattress—just dampen the spot. Let sit for 15–20 minutes.
3. Blot again
Use another clean cloth to lift moisture and urine from the mattress. Repeat steps 2–3 until the stain disappears.
4. Deodorize with baking soda
Sprinkle a thick layer of baking soda over the area. Let it sit for at least 8 hours to absorb smells and moisture.
5. Vacuum thoroughly
Once dry, vacuum up the baking soda. Use a brush attachment for a deeper clean.
💡 Still smells? Spray an enzyme cleaner made for urine and let it work its magic.
💦 How to Remove Fresh Pee from a Mattress
Best for: New accidents from kids or pets.
What you’ll need: White vinegar, baking soda, paper towels, spray bottle.
1. Strip the bed
Remove all bedding and wash in hot water with detergent. Add 1 cup of white vinegar or use an enzyme detergent for heavy odors.
2. Blot the excess urine
Use paper towels or a white cloth to absorb as much pee as possible. Blot—don’t rub—to avoid spreading the stain.
3. Apply baking soda
Sprinkle baking soda over the damp spot to pull out remaining urine and start deodorizing.
4. Spray vinegar solution
Mix equal parts white vinegar and water in a spray bottle. Mist the area until damp—not soaked. Let it sit for 5 minutes.
✨ Add a few drops of dish soap for a stronger cleaner.
5. Blot and reapply baking soda
Dab with a clean cloth, then sprinkle another light layer of baking soda. This helps neutralize urine odors.
6. Let dry for 18 hours
Allow the mattress to air dry completely. Use fans or open windows for faster drying.
7. Vacuum up the powder
Once dry, vacuum away the baking soda. Still smell pee? Repeat the process or switch to the hydrogen peroxide method.
🧼 How to Remove Urine Odors from a Mattress
Even after stains are gone, pee smells can linger. Here’s how to deodorize completely:
1. Cover the mattress with baking soda
Apply a thin layer of baking soda over the entire surface. Let it sit for 8–10 hours to absorb deep odors.
2. Vacuum it up
Use a handheld vacuum or brush attachment to clean off the powder. Still smells? Reapply baking soda or use an enzyme spray.
3. Use an enzyme cleaner for stubborn smells
Pet pee or repeat accidents? Spray an enzyme-based urine cleaner directly on the area. Let it sit for 1 hour, then blot dry.
Conclusion:
Whether you're tackling fresh pee on a memory foam mattress or trying to remove dried urine smells, the combination of hydrogen peroxide, baking soda, white vinegar, and enzyme cleaners can restore your bed without stress. Just be patient, let the ingredients work, and always allow your mattress to dry completely before making the bed again.
