What does “disinfecting” a urine-stained mattress really mean?
When people ask how to disinfect a mattress urine, they usually want to:
- Remove visible stains

Act quickly. The faster you respond, the easier it is to clean and disinfect a mattress after urine.
Strip the bed
Remove sheets, protector, and any bedding. Wash them according to their care labels.Blot, don’t rub
Use paper towels or a clean dry cloth to press firmly on the wet area.- Do not scrub; this pushes urine deeper into the mattress.
Apply a simple cleaning solution
Mix:- 1 part mild liquid dish soap
- 4–5 parts cool water
Lightly dampen (do not soak) a clean cloth and dab the affected area.
Use an enzyme cleaner (optional but helpful)
An enzymatic cleaner formulated for urine can help break down odor-causing residues.- Lightly mist the spot.
- Let it sit as directed on the label.
- Blot again to remove excess moisture.
Dry thoroughly
- Open windows or use a fan.
- If possible, stand the mattress on its side to allow airflow.
A mattress that dries quickly is less likely to hold persistent odors.
How do I disinfect a mattress after urine has dried?
Dried stains are more stubborn, but you can still improve them.
Step 1: Lightly rehydrate the stain
Mix a solution of equal parts cool water and white vinegar in a spray bottle. Lightly spray just the stained area.
- Vinegar helps neutralize odors.
- Avoid soaking the mattress; extra moisture can be trapped inside.
Step 2: Blot and lift
After a few minutes, blot the area with a clean cloth to lift discoloration and moisture.
Step 3: Deodorize with baking soda
Sprinkle a generous layer of baking soda over the damp area.
- Leave it on for several hours, or ideally overnight.
- Baking soda helps absorb both moisture and odor.
Vacuum the mattress thoroughly to remove all powder.
