How To Clean a Mattress Of Pee: Simple Steps That Actually Work

If you’re searching for How To Clean a Mattress Of Pee, you’re likely dealing with a fresh accident or an old stain that just won’t go away. This guide walks you through what to do right now, how to handle dried stains and odors, and how to help protect your mattress in the future.

What’s the Best Way To Clean Fresh Pee From a Mattress?

When urine is fresh, quick action makes the biggest difference.

Step-by-step guide for fresh accidents:

  1. Remove bedding immediately
    Strip sheets, blankets, and mattress protectors so the moisture doesn’t spread.

  2. Blot, don’t rub
    Use clean, absorbent towels or paper towels to press firmly into the wet area.

    • Avoid scrubbing: it can push urine deeper into the mattress.

  3. Apply a mild cleaning solution
    A common option is a mix of:

    • Cool water
    • A small amount of gentle liquid detergent or mild soap
      Lightly spray or dab the solution onto the stained area—do not soak the mattress.

  4. Blot again to remove moisture
    Press with dry towels to absorb as much liquid as possible. Repeat as needed.

  5. Use baking soda to absorb and deodorize
    Sprinkle a generous layer of baking soda over the damp area.

    • Let it sit for several hours, ideally until fully dry.

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

For many people, this basic method is enough to clean a fresh pee accident and reduce odors significantly.

How To Clean a Mattress Of Pee Once It Has Dried?

Dried stains can be more stubborn because they’ve had time to seep into the mattress.

Can I still remove old urine stains?

You can often lighten or greatly reduce older urine stains and smells, even if they don’t disappear completely.

Approach for dried pee:

  1. Lightly re-dampen the area
    Mist the stained area with a small amount of water. This can help loosen dried residue.

  2. Use a gentle cleaning mix
    Many people use household mixtures designed for stain removal, often involving:

    • Mild soap or detergent
    • Water
      Apply sparingly so you don’t oversaturate the mattress.

  3. Let it sit briefly
    Give the solution some time to work, usually 10–15 minutes.

  4. Blot thoroughly
    Press with clean, dry towels to remove as much moisture as possible.

  5. Deodorize with baking soda
    Cover the spot with baking soda and leave it for several hours or overnight.

  6. Vacuum and reassess
    Vacuum up the baking soda and check both the stain visibility and smell.

    • Some older stains may need a second round of cleaning.

How Do I Get Rid of the Smell of Pee in a Mattress?

Odor is one of the biggest concerns when people look up How To Clean a Mattress Of Pee.

Why does the smell linger?

Urine can seep below the surface fabric into the foam or padding. If moisture stays trapped, odor can persist even after the top looks clean.

Practical odor-reduction tips

  • Air out the mattress
    If possible, stand the mattress upright in a well-ventilated room or near an open window.

  • Use baking soda generously
    A thick layer left for many hours often absorbs more odor than a quick sprinkle.

  • Repeat treatments
    It’s common to need multiple rounds of cleaning and deodorizing for strong smells.

If odor remains after several careful attempts, some people choose to focus on prevention and coverage (with protectors and fresh bedding) while continuing light deodorizing treatments over time.

What Should I Avoid When Cleaning Pee From a Mattress?

Knowing what not to do is just as important.

  • Do not soak the mattress
    Excess liquid can seep deep inside, making drying difficult and odors worse.
  • Avoid harsh chemicals or strong bleach
    These can discolor fabrics and may damage some mattress materials.
  • Skip aggressive scrubbing
    Scrubbing can spread the stain and push it further into the mattress layers.
  • Don’t leave the mattress damp
    Always allow plenty of time for complete drying before putting sheets back on.

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

Drying time depends on how much liquid was used, room temperature, and airflow.

  • Lightly treated spots may dry within a few hours.
  • Deeper cleanings can take most of the day.

Helpful drying tips:

  • Open windows or use a fan to improve air circulation.
  • If safe for your mattress type, place it in a sunny spot for brief periods to speed drying.

Always make sure the mattress is fully dry before covering it again.

How Can I Prevent Future Pee Stains on My Mattress?

After dealing with an accident once, many people look for ways to protect the mattress going forward.

Common preventative steps:

  • Use a mattress protector to create a barrier between the sleeper and the mattress.
  • Layer bedding so you can quickly remove and wash top layers if another accident happens.
  • Check the mattress regularly so you can catch any new stains early, when they’re easier to clean.
