How To Clean Pee Smell From Mattress: Simple Steps That Actually Work
If you’re searching for “How To Clean Pee Smell From Mattress”, you’re likely dealing with a fresh accident or a lingering odor that just won’t go away. This guide walks you through practical, home-friendly methods to remove both the stain and the smell, and answers the most common questions people have about urine on mattresses.
Why Does Pee Smell Linger in a Mattress?
A mattress is thick and absorbent, so urine can quickly soak deep into the layers. Even if the surface looks clean, odor-causing residues can remain inside and continue to smell over time.
The smell tends to be stronger when:
- The stain is older or has dried several times
- The mattress wasn’t cleaned promptly
- Only the surface was wiped (without deodorizing deeper layers)
That’s why knowing how to clean pee smell from a mattress properly is important for keeping your bed fresh and comfortable.
How To Clean Pee Smell From Mattress: Step-by-Step
Step 1: Act Quickly (If the Stain Is Fresh)
Blot, don’t rub.
Use clean, dry towels or paper towels to press firmly and soak up as much liquid as possible. Rubbing can push the urine deeper into the mattress.Remove bedding immediately.
Wash sheets and covers according to their care labels using regular detergent.
Step 2: Clean the Stain
A simple cleaning mix many people use at home:
- 1 part mild liquid detergent (or dish soap)
- 2 parts cool water
- Lightly dab the stained area with the solution using a clean cloth.
- Blot again with a dry towel to remove extra moisture.
- Avoid soaking the mattress; too much liquid can be hard to dry and may cause a musty smell.
How Do You Remove the Pee Smell, Not Just the Stain?
Even after cleaning, a faint odor may remain. To target the smell, many people rely on baking soda and a gentle vinegar solution, both commonly used for household deodorizing.
Step 3: Use Vinegar Solution for Odor
Mix:
- 1 part white vinegar
- 2 parts water
- Lightly spray or dab the affected area.
- Let it sit for 5–10 minutes.
- Blot thoroughly with a dry towel.
Vinegar has a strong smell at first, but it usually fades as it dries.
Step 4: Deodorize With Baking Soda
- Sprinkle a generous layer of baking soda over the damp area.
- Gently spread it out so it covers slightly beyond the original stain.
- Leave it on for at least several hours, or overnight if possible.
- Vacuum up the baking soda slowly using an upholstery attachment.
If odor remains, this baking soda step can be repeated.
😮 What If the Pee Stain Is Old or Already Dry?
Dried urine can be more stubborn, but the process is similar with a bit more patience.
H3: Steps for Older Pee Smells
- Lightly re-dampen the area with a vinegar-and-water mix. This helps loosen dried residue.
- Blot to remove excess moisture.
- Apply baking soda as described above.
- Let it sit longer (overnight is helpful).
- Vacuum thoroughly.
For very persistent smells, multiple rounds of vinegar + baking soda may help reduce the odor over time.
Can You Use Enzyme Cleaners on a Mattress?
Many people use enzyme-based cleaners designed for organic stains such as urine. These products aim to break down odor-causing residues.
If you choose to use one:
- Check that it’s safe for upholstery or mattresses.
- Test it on a small, hidden area first.
- Follow the instructions carefully, especially drying times.
Enzyme cleaners are often used when home remedies aren’t enough or when the smell has been present for a long time.
How Long Does It Take a Mattress to Dry After Cleaning?
Drying time depends on:
- How much liquid was used
- Room temperature and airflow
- Mattress thickness and material
To help your mattress dry:
- Open windows or turn on a fan
- Use a gentle, cool air setting if you have a fan or similar device
- Avoid sleeping on the mattress until it feels dry to the touch
A mattress that stays damp for too long may develop a musty odor, so thorough drying is essential.
How Do You Prevent Future Pee Smells in a Mattress?
A few simple habits can make accidents easier to handle:
- Use a waterproof mattress protector to keep liquids from soaking in.
- Clean accidents as soon as possible to reduce staining and odor.
- Air out your mattress occasionally by removing bedding during the day.
These steps won’t stop accidents from happening, but they can make cleanup much quicker and more effective.
