How To Get Rid Of Urine Odor In Mattress: Simple, Effective Steps
If you’re searching for “How To Get Rid Of Urine Odor In Mattress”, you’re likely dealing with a fresh accident or a lingering smell that just won’t go away. This guide walks through what actually works, why odor can be so stubborn, and how to treat both fresh and old urine smells without damaging your mattress.
Why Does Urine Odor Linger In a Mattress?
Mattresses are thick and absorbent. When urine soaks in, it can:
- Penetrate multiple layers, not just the surface fabric
- Leave behind uric acid crystals and other compounds that cause lasting odor
- Become harder to remove once it dries and sets
The goal is to break down and flush out those odor-causing residues, not just cover them with fragrance.
First Steps: What To Do Right After an Accident
How should I treat fresh urine on a mattress?
Acting quickly gives you the best chance of preventing a long-term smell.
Blot, don’t rub
- Use clean, dry towels or paper towels.
- Press firmly to absorb as much liquid as possible.
- Avoid scrubbing, which can push urine deeper into the mattress.
Apply a mild cleaning solution
- Mix cool water with a small amount of gentle, dye-free dish soap.
- Lightly dab the area; don’t soak the mattress.
Blot again thoroughly
- Remove as much moisture as possible with dry towels.
- The drier you get it now, the less odor will linger later.
How To Get Rid Of Urine Odor In Mattress Using Household Cleaners
What’s the best deodorizing method for urine smell?
A common, mattress-safe approach uses white vinegar and baking soda:
Vinegar solution
- Mix 1 part white vinegar with 2–3 parts water.
- Lightly spray or dab onto the affected area.
- Vinegar helps neutralize many urine odors instead of just masking them.
Let it sit
- Allow 10–15 minutes of contact time.
- Avoid over-saturating the mattress; use just enough to dampen the area.
Blot thoroughly
- Use clean towels to remove as much liquid as possible.
Apply baking soda
- Sprinkle a generous, even layer of baking soda over the damp area.
- Baking soda helps absorb residual moisture and odor.
Leave it for several hours
- Ideally, let it sit overnight.
- Keep the room ventilated if possible.
Vacuum
- Once completely dry, vacuum the baking soda slowly and thoroughly.
This process can be repeated if a faint odor remains after the first attempt.
What About Old or Set-In Urine Odor?
Can I remove urine odor that’s been there for a long time?
Older stains and smells are harder to treat, but often still improve with patience.
Repeat the vinegar and baking soda method
Several rounds may gradually reduce the smell.Use an enzyme cleaner designed for fabrics
Enzyme-based cleaners are commonly used on organic stains like urine. They are formulated to break down odor-causing compounds rather than just covering them.General tips:
- Test on a small, hidden area first.
- Follow the product’s instructions carefully.
- Avoid mixing enzyme cleaners with vinegar or other chemicals in the same step, as that can reduce their effectiveness.
Give it time to dry completely
Mattresses can stay damp inside even when the surface feels dry. Persistent dampness can trap odors, so full drying is essential.
Drying and Odor Prevention Tips
How do I dry the mattress properly?
After cleaning, focus on airflow and time:
- Open windows or use a fan to improve air circulation
- If safe for your mattress type, use a cool or low heat setting on a hair dryer at a distance to speed up surface drying
- Allow extra hours for the interior to air out, not just the surface
Avoid putting bedding back on until the mattress feels and smells dry.
How can I prevent future urine odors?
Once you’ve learned How To Get Rid Of Urine Odor In Mattress, it’s helpful to reduce the chance of repeat issues:
- Use a waterproof mattress protector to keep liquids out of the mattress core
- Clean accidents as soon as they happen to prevent deep absorption
