How To Get Pee Out Of Mattress: Step‑By‑Step FAQ Guide

If you’re searching for “How To Get Pee Out Of Mattress”, you’re likely dealing with a fresh accident or a lingering stain and smell. This guide walks you through what to do right now, how to handle dried urine, and how to protect your mattress going forward.

Why Is It So Hard To Get Pee Out Of a Mattress?

Mattresses are thick, absorbent, and usually covered in fabric that doesn’t unzip easily. When urine soaks in, it can:

  • Leave yellowish stains
  • Create a persistent odor
  • Attract bacteria and moisture if not cleaned

Because you usually can’t toss a mattress in the washing machine, you need surface-safe methods that reach into the foam and comfort layers without soaking them.

How To Get Pee Out Of Mattress (Fresh Stains)

What should I do immediately after an accident?

Act quickly. The fresher the urine, the easier it is to remove.

  1. Strip the bed
    Remove sheets, protectors, and any bedding. Wash them according to their labels.

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

    • Do not scrub; rubbing can push urine deeper into the mattress.

  3. Apply a mild cleaning solution
    A commonly used option for fresh stains:

    • Mix equal parts cool water and white vinegar in a spray bottle.
    • Lightly spray the affected area until damp (not soaked).
    • Let it sit for 5–10 minutes.

  4. Blot again
    Use dry towels to remove as much moisture as possible.

  5. Deodorize with baking soda
    Sprinkle a generous layer of baking soda over the damp area.

    • Leave it for several hours, or ideally overnight, to absorb moisture and odor.

  6. Vacuum thoroughly
    Once dry, vacuum up the baking soda using a brush or upholstery attachment.

How Do I Remove Dried or Old Pee Stains?

Can I still clean my mattress if the urine is already dry?

Yes. Dried stains usually take more time and possibly repeat treatments, but they can often be improved significantly.

What’s a good method for set-in urine stains?

  1. Lightly re-dampen the area
    Mist the stain with plain water or a diluted vinegar solution (about 1 part vinegar to 2 parts water). The goal is to loosen dried residue, not soak the mattress.

  2. Gently blot
    Press with a clean cloth to lift loosened urine.

  3. Use an enzymatic cleaner (optional)
    Many people use enzyme-based cleaners designed for organic stains like urine. These products are formulated to break down odor-causing compounds.

    • Test a small, hidden patch first to check for discoloration.
    • Apply according to the product instructions.
    • Allow plenty of time to air dry.

  4. Apply baking soda afterward
    Once the main cleaning step is done, cover the area with baking soda again to absorb remaining moisture and odor. Let it sit, then vacuum.

You may need to repeat the process for deeply set or older stains.

Is It Safe To Use Hydrogen Peroxide or Stronger Solutions?

Some people use mixtures with hydrogen peroxide, dish soap, and baking soda to target tougher stains. These can help with discoloration but carry some risks:

  • Peroxide may lighten fabrics or mattress ticking
  • Too much liquid can over-saturate the mattress, slowing drying and encouraging odors

If you choose to use such mixtures:

  • Use a low concentration of peroxide
  • Test on a small, hidden area first
  • Apply sparingly and avoid soaking the mattress

For delicate fabrics or specialty materials, milder solutions are often safer.

How Do I Get Rid of the Smell Completely?

Why does the odor linger even after cleaning?

Urine odor can stick around if residue remains inside the mattress or if the mattress didn’t fully dry. Warm, slightly damp conditions can make smells more noticeable.

What helps remove pee smell from a mattress?

  • Thorough drying
    After cleaning, allow complete air drying. If possible:

    • Open windows or use a fan
    • Avoid putting bedding back on until the mattress is fully dry

  • Baking soda as a final step
    Even after cleaning, a fresh layer of baking soda left for several hours can help with lingering odor.

  • Repeat treatments
    For stubborn smells, more than one round of cleaning is often needed.

How Can I Protect My Mattress From Future Accidents?

Once you’ve learned How To Get Pee Out Of Mattress, it makes sense to protect it so the cleanup is easier next time.

Common protective steps include:

  • Water-resistant mattress protectors that act as a barrier
  • Washable mattress pads that can be removed and laundered
  • Regular spot checks so small accidents don’t become long-term stains

These layers usually take the brunt of any spills or accidents, so your mattress itself stays cleaner and drier.

❓ Common Follow-Up Questions About Cleaning Pee From a Mattress

Can I use a steam cleaner?

Steam can push moisture deeper into the mattress and may not dry quickly, which can lead to more odor. Many people avoid steam cleaning for this reason and prefer surface treatments that dry faster.

How long does a mattress take to dry after cleaning?

Drying time depends on how much liquid was used and room conditions. Many mattresses need several hours or longer. A fan, open window, or low-heat air setting can help speed things up.

When should I consider replacing the mattress?

If urine has soaked deeply into the mattress many times, or if odor and staining remain even after multiple careful cleanings, some people eventually choose to replace it, especially for comfort, hygiene, or peace of mind.
