How To Get Pee Smell Out Of Mattress: Simple Steps That Actually Help
If you’re searching for “How To Get Pee Smell Out Of Mattress”, you’re likely dealing with a fresh accident, an older stain, or a lingering odor that just won’t go away. This guide explains why urine smells stick, how to remove them step by step, and what to do if the smell keeps coming back.
Why Does Pee Smell Stay In a Mattress?
Mattresses are thick and absorbent. When urine soaks in, it:
- Penetrates foam and fabric layers
- Dries slowly, giving odor-causing compounds time to set
- Can leave behind crystals and residue that reactivate with moisture or humidity
That’s why simply spraying a fresh scent on top rarely fixes the problem. To truly learn how to get pee smell out of mattress surfaces, you need to lift, break down, and neutralize what’s inside the fabric and foam.
What Should I Do Right After an Accident?
Step 1: Blot, Don’t Rub
For fresh pee:
- Remove bedding immediately.
- Use clean, dry towels or paper towels to blot the wet area.
- Press down firmly to draw out as much liquid as possible.
Avoid scrubbing. Rubbing pushes urine deeper into the mattress instead of removing it.
Step 2: Use a Gentle Cleaning Solution
Common options include:
- Mild dish soap and cool water
- A water and white vinegar mixture (often about equal parts)
Lightly dampen (do not soak) the area and blot again. The goal is to lift urine, not to flood the mattress.
How To Get Pee Smell Out Of Mattress Using Common Household Ingredients
Step 3: Apply a Deodorizing Layer
Once you’ve cleaned the spot:
- Lightly mist the area with a vinegar-and-water solution if you haven’t already.
- While it is still slightly damp, generously sprinkle baking soda over the area.
Baking soda is commonly used to absorb odors and moisture from fabrics and foam.
Step 4: Let It Sit — The Longer, The Better
Allow the baking soda to sit for several hours, or ideally overnight. This gives it time to:
- Draw out remaining moisture
- Help neutralize residual smells
Keep the room well-ventilated to help the mattress dry.
Step 5: Vacuum Thoroughly
Once everything is completely dry:
- Use a vacuum with an upholstery attachment to remove all the baking soda.
- Go over the area slowly to pick up fine powder from fabric seams and surface pores.
If the smell is still noticeable, you can repeat the process once or twice.
What About Old or Set-In Pee Smells?
Dried urine can be more stubborn. For older stains:
- Lightly re-dampen the area with a cleaning solution (water plus a small amount of gentle soap or vinegar mixture).
- Avoid soaking the mattress; too much liquid can cause mold or lingering dampness.
- Repeat the baking soda and vacuum method.
Some people also use enzyme-based cleaners designed for organic stains. These are often used on fabrics and soft surfaces. Always test a small hidden patch first and follow any directions on the product.
Is It Safe to Use Strong Chemicals or Perfumes?
Using very strong chemicals, heavy perfumes, or undiluted cleaners can:
- Irritate skin or breathing for some sleepers
- Potentially damage foam or fabrics
- Mask odors temporarily instead of removing them
For most situations, gentle cleaners, vinegar solutions, and baking soda are commonly used because they are relatively mild and widely available.
If you’re unsure about a cleaner, test a small area on the side or bottom of the mattress before using it on a large section.
How Can I Prevent Future Pee Smells in My Mattress?
Once you’ve figured out how to get pee smell out of mattress materials, prevention becomes much easier:
- Use a waterproof mattress protector to create a barrier between spills and foam.
- Wash bedding promptly after any accident.
- Air out your mattress occasionally by removing all bedding and opening windows when possible.
- Address accidents as soon as you notice them to reduce staining and odor.
When Is It Time to Consider That the Smell Won’t Come Out?
Sometimes, repeated accidents or deep, long-standing stains can make odor very difficult to remove. Signs your mattress may be too affected include:
- A persistent, strong smell even after several thorough cleanings
- Noticeable discoloration over a large area
- A feeling that the mattress is damp deep inside, even after drying time
In those cases, further cleaning may reduce but not completely remove the issue.
✔️ Quick Mattress Takeaways
Key points to understand about How To Get Pee Smell Out Of Mattress:
- Act quickly: Blot fresh urine immediately; don’t rub or scrub.

- Deodorize deeply: Let baking soda sit for several hours, then vacuum thoroughly.
- Repeat if needed: Old or set-in smells may require more than one treatment.
- Test new products: Always try cleaners on a hidden area first.
- Protect going forward: A waterproof protector and quick cleanup can prevent future odors.
With a calm, step-by-step approach, most people can significantly reduce or remove urine odor and feel more comfortable using their mattress again.
