How Do You Remove Pee From a Mattress? Practical Steps That Actually Help

If you’re searching “How Do You Remove Pee From a Mattress”, you’re likely dealing with a fresh accident or an old stain that won’t go away. The good news: with the right steps, you can usually remove urine stains and reduce odor without damaging your mattress.

This FAQ-style guide walks you through what to do, what to avoid, and how to handle both fresh and dried pee on a mattress.

What’s the Best Way to Treat Fresh Pee on a Mattress?

When the accident is recent, acting quickly makes a big difference.

Step-by-step for fresh urine:

  1. Remove bedding immediately
    Strip sheets, covers, and protectors so urine doesn’t spread further.

  2. Blot, don’t rub
    Use clean, absorbent towels or paper towels.
    Press firmly to soak up as much liquid as possible. Avoid scrubbing, which can push urine deeper into the mattress.

  3. Apply a gentle cleaning solution
    Common mild options include:

    • A mix of lukewarm water and a small amount of mild detergent, or
    • A solution of water and white vinegar (often about equal parts).
      Lightly spray or dab the solution onto the affected area—do not soak the mattress, as excess moisture can be hard to dry.

  4. Blot again
    After applying the solution, blot with a dry towel to remove extra moisture and cleaner.

  5. Use baking soda to help with odor
    Sprinkle a generous layer of baking soda over the damp area.
    Let it sit for several hours, or ideally overnight, so it can absorb remaining moisture and smell.

  6. Vacuum thoroughly
    Once the baking soda is completely dry, vacuum it up using an upholstery attachment if available.

How Do You Remove Pee From a Mattress If It Has Already Dried?

Dried urine can leave visible stains and lingering odor. The process is similar, but you may need more than one round of cleaning.

  1. Lightly re-dampen the area
    Use a spray bottle with plain water or a mild water-and-vinegar solution to slightly moisten the stained area. This can help loosen dried residue.

  2. Apply your cleaning solution
    Use the same type of gentle cleaner mentioned above. Allow it to sit for 10–15 minutes, but avoid saturating the mattress.

  3. Blot moisture out
    Use dry towels to pull as much liquid out as possible.

  4. Add baking soda
    Cover the area with baking soda and let it rest for several hours. This step is especially helpful for older smells.

  5. Vacuum and assess
    After vacuuming, check the stain and smell. Some old or set-in stains may need a second or third round of treatment.

Can You Completely Remove the Smell of Urine?

Urine odor can be stubborn, especially if it has soaked deeply or gone untreated for a while. In many cases, smell can be significantly reduced with:

  • Thorough blotting and cleaning
  • Multiple rounds of baking soda treatments
  • Plenty of airflow and drying time

For persistent odor that doesn’t improve, many people consider:

  • Repeating the cleaning process on a slightly larger area around the original spot
  • Allowing more time for full drying between attempts
  • Using odor-focused cleaning products designed for home fabrics (always test a small hidden area first)

Is It Safe to Use Bleach or Harsh Cleaners on a Mattress?

Most mattresses are not designed for harsh chemicals. Strong cleaners can:

  • Damage fabrics and foams
  • Discolor the surface
  • Leave their own strong odor behind

In general, mild, fabric-safe cleaners are preferred. Always:

  • Test the cleaner on a small, hidden section first
  • Follow any care instructions that came with your mattress
  • Avoid soaking the mattress with any liquid, even water

How Long Does It Take a Mattress to Dry After Cleaning?

Drying time depends on:

  • How much liquid was used
  • Room temperature and ventilation
  • Mattress materials and thickness

To help your mattress dry more quickly:

  • Open windows or use a fan to increase airflow
  • If possible, stand the mattress partly upright to expose more surface area
  • Wait until the mattress is completely dry before putting sheets back on, to help prevent odor and moisture buildup

How Can You Prevent Future Pee Stains on a Mattress?

While accidents happen, a few simple steps can limit damage next time:

  • Use a washable, waterproof mattress protector
  • Keep extra bedding and towels handy for quick clean-up
  • Check the mattress soon after any accident so you can treat it while fresh
