What’s the best way to clean fresh urine off a mattress?
For fresh accidents, acting quickly is the most effective approach. Here’s a simple process many people use at home:
Remove bedding immediately
- Strip the sheets, protectors, and blankets.
- Blot any wet areas on the bedding with a towel before laundering.
Blot the urine, don’t rub
- Use clean, absorbent towels or paper towels.
- Gently press down to soak up as much liquid as possible.
- Avoid scrubbing, which can push urine deeper into the mattress.
Apply a simple cleaning solution
A commonly used household mix is:- Cool water
- A small amount of mild liquid detergent or gentle dish soap
- Optional: a bit of white vinegar to help with odor
Lightly spray or dab the solution onto the stained area. Do not saturate the mattress; too much moisture can be hard to dry and may cause lingering odors.
Blot again until mostly dry
- Use dry towels to remove excess moisture.
- Press firmly, replacing towels as needed.
Use baking soda for odor and moisture
- Sprinkle a generous layer of baking soda over the damp area.
- Let it sit for several hours, or overnight if possible, to absorb moisture and smell.
Vacuum the baking soda
- Once completely dry, vacuum the mattress thoroughly.
- Check for remaining odor or stain and repeat if needed.
How To Clean Urine Off Of a Mattress if the stain is old or dried?
Dried urine can be more stubborn because it has already set into the mattress fibers. You can still improve or significantly reduce the stain and odor with patience:
Lightly re-dampen the area
- Use a small amount of water or a mild cleaning solution to moisten the stained spot.
- This helps loosen dried residue.
Use a targeted cleaning solution
Many people find that a combination of water, mild detergent, and white vinegar can help break down dried urine. Apply sparingly and avoid soaking.Let it sit
- Allow the solution to rest on the stain for about 10–15 minutes.
- This gives it time to work on surface residues.
Blot thoroughly
- Blot with clean towels until the area is as dry as possible.
Apply baking soda again
- Cover the spot with baking soda and leave for several hours or overnight.
- Vacuum when dry.
Deep, long-standing stains may not disappear completely, but consistent gentle cleaning often improves both the look and smell over time.
