How Do You Clean a Mattress From Pee? Step‑by‑Step Guide & FAQ

If you’re searching “How Do You Clean a Mattress From Pee”, you’re likely dealing with a fresh accident or a lingering urine stain and smell. This guide walks you through simple, at-home methods to clean pee from a mattress, protect the materials, and reduce odors as much as possible.

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

For fresh accidents, acting quickly is the most important step. Here’s a simple process you can follow:

  1. Remove bedding immediately
    Strip sheets, protectors, and mattress covers and place them in the wash according to their care labels.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to blot up as much liquid as possible.

    • Press firmly to absorb moisture.
    • Avoid rubbing, which can push urine deeper into the mattress.

  3. Apply a gentle cleaning solution
    Common options include:

    • A mixture of mild dish soap and cool water
    • A mixture of white vinegar and water (often half and half)
      Lightly spray or dab the solution onto the affected area—do not soak the mattress.

  4. Blot again to remove moisture
    After applying your solution, blot thoroughly with clean, dry cloths to pull out both the liquid and some of the urine.

  5. Deodorize with baking soda
    Sprinkle a generous layer of baking soda over the damp spot. This can help absorb moisture and some odor.

  6. Let the mattress dry completely
    Allow several hours for the mattress to air-dry. Good airflow, a fan, or open windows can help.
    Once dry, vacuum up the baking soda.

How Do You Clean a Mattress From Pee Once It Has Dried?

Dried urine can leave behind stains and stubborn odors. The approach is similar, but may require a bit more time and repetition.

Step-by-step for dried urine stains

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

  2. Use a gentle cleaning solution
    Apply:

    • Mild soap and water solution, or
    • Vinegar and water solution
      Dab the solution on with a cloth or spray lightly, then let it sit for a short period (about 5–10 minutes).

  3. Blot thoroughly
    Use clean towels to press and lift out as much liquid as possible.

  4. Apply baking soda again
    Cover the area with baking soda and leave it for several hours, or even overnight, for better odor absorption.

  5. Vacuum and inspect
    Once dry, vacuum the baking soda and check the stain and smell.

    • If needed, you can repeat the process to further reduce discoloration and odor.

Will Cleaning Pee Damage My Mattress?

When you’re figuring out how to clean a mattress from pee, it’s natural to worry about damaging the materials.

Key things to keep in mind:

  • Avoid soaking the mattress. Excess liquid can seep deep inside, making it harder to dry and potentially affect the internal layers.
  • Use mild cleaners. Strong chemicals or bleach can be harsh on fabrics and foams and may cause discoloration.
  • Follow any care instructions provided by the mattress manufacturer, especially for specialty materials.

A careful, gentle approach with minimal moisture and mild solutions is usually the safest route.

How Can I Get Rid of Urine Smell in a Mattress?

Even after cleaning, you may notice a lingering smell. Odor reduction often depends on how quickly you treated the spill and how deeply it soaked.

Common strategies include:

  • Thorough blotting and cleaning as described above
  • Repeating the baking soda treatment over several hours
  • Good ventilation: open windows, fans, and time can help odors fade

If odor remains despite several attempts, it may be due to urine that has penetrated deep into the mattress layers, where surface cleaning is less effective.

Can You Clean All Types of Mattresses the Same Way?

Most mattresses, including foam and hybrid styles, benefit from a similar surface-only cleaning approach, but:

  • Do not machine-wash the mattress itself.
  • Avoid steam cleaning unless you know your specific mattress type can handle moisture and heat.
  • Check any tags or instructions that came with your mattress. Some materials are more sensitive to liquid than others.

If your mattress has a removable, washable cover, you can usually wash the cover separately and then clean the inner mattress surface more gently.

How Can I Prevent Future Pee Stains on a Mattress?

While accidents happen, a few steps can make cleanup much easier next time:

  • Use a water-resistant mattress protector
  • Wash bedding regularly
  • Address spills or accidents as quickly as possible

Preventing liquid from reaching the inner layers of the mattress is often the most effective way to keep it cleaner over time.
