What Happens When Pee Gets On a Mattress?

- Unpleasant odours
- A feeling that the mattress is less fresh or hygienic
Acting quickly usually makes how to clean pee out of mattress much easier, but even dried stains can often be improved with the right approach.
How To Clean Fresh Pee Out Of a Mattress
Step-by-step for a fresh accident
Strip the bed immediately
Remove sheets, mattress protector, and bedding so urine doesn’t spread further.Blot, don’t rub
Use clean, absorbent towels or paper towels.- Press firmly to soak up as much as possible.
- Avoid scrubbing, which can push liquid deeper into the mattress.
Apply a gentle cleaning solution
Mix a mild solution of water and a small amount of gentle liquid detergent or a simple household cleaner suitable for fabrics.- Lightly spray or dab the affected area.
- Do not saturate the mattress; too much liquid can be hard to dry.
Blot again
Use dry towels to pull up moisture from the mattress surface and just below it.Use baking soda to absorb moisture and odour
Sprinkle a generous layer of baking soda over the damp area.- Leave it on for several hours, ideally until fully dry.
Vacuum thoroughly
Once dry, vacuum the baking soda to remove residue and odour.
How To Clean Dried Pee Out Of a Mattress
Older stains are more stubborn, but you can still often improve them.
Extra steps for dried or set-in stains
Lightly re-dampen the stained area
Use a small amount of water or a gentle cleaning mixture. The goal is to loosen the dried urine, not soak the mattress.Apply a targeted cleaner
A mild, fabric-safe cleaning solution or an enzyme-based cleaner designed for organic stains is commonly used for these situations.- Follow the product’s instructions carefully.
- Test any cleaner on a small, hidden area of the mattress first.
Blot, then wait
Blot away excess moisture, then allow time for the cleaner to work and the mattress to dry.Finish with baking soda and vacuuming
Just like with fresh stains, baking soda can help control any remaining odour.
Will the Smell Go Away Completely?
Odour removal depends on:
- How long the urine sat in the mattress
- How deeply it soaked in
- The type and thickness of the mattress
Often, careful cleaning plus baking soda helps greatly reduce or remove odours. In some cases, especially with repeated accidents, a faint smell may remain. Repeating the process or using an odour-focused cleaner can be helpful.
Is It Safe To Use Strong Chemicals on a Mattress?
It’s best to be cautious:
- Avoid harsh chemicals that could irritate skin or damage mattress materials.
- Avoid soaking the mattress with bleach or heavily perfumed products.
- Always spot-test in an inconspicuous area first.
Mattresses are not designed to be heavily washed, so using minimal liquid and mild products is usually safest.
How Can I Dry the Mattress Faster?
Proper drying is essential to avoid musty smells:
- Open windows or improve room ventilation.
- Use a fan or place the mattress in a well-ventilated space.
- If possible, stand the mattress on its side to allow more air circulation.
Avoid putting bedding back on until the mattress is fully dry to the touch.
