How To Clean Mattress That Has Been Peed On: Simple Steps That Actually Work

If you’re searching for “How To Clean Mattress That Has Been Peed On”, you’re likely dealing with a fresh accident or a lingering stain and smell. This guide walks you through exactly what to do, what to avoid, and how to handle both fresh and dried urine on a mattress.

What’s the best way to clean a mattress that has been peed on?

The basic process is:

  1. Act fast if it’s fresh.
  2. Blot, don’t rub.
  3. Use a gentle cleaning solution that breaks down urine.
  4. Dry thoroughly to avoid lingering odor and moisture.

Here’s a simple step‑by‑step method many people use at home:

  1. Strip the bed
    Remove sheets, protectors, and blankets right away and wash them according to their care labels.

  2. Blot the urine
    Use clean, dry towels or paper towels to press firmly into the wet area.

    • Do not scrub; scrubbing pushes urine deeper into the mattress.

  3. Apply a cleaning solution
    Common options include:

    • A mix of mild liquid soap and cool water
    • A white vinegar and water solution (often about 1:1)
      Lightly spray or dab onto the stained area. The goal is to dampen, not soak, the mattress.

  4. Blot again
    After letting the solution sit for a few minutes, blot out as much moisture as you can with dry towels.

  5. Deodorize with baking soda
    Sprinkle a generous layer of baking soda over the area. Leave it for several hours, or ideally overnight, to absorb odor and moisture.

  6. Vacuum thoroughly
    Once the baking soda is completely dry, vacuum it up slowly to remove the powder.

  7. Let the mattress air dry fully
    Allow plenty of time for the mattress to dry before putting bedding back on. Good airflow, fans, or open windows can help.

How do I clean dried or old urine stains?

When learning How To Clean Mattress That Has Been Peed On after the stain has already dried, the focus is on re-hydrating and lifting the stain and odor.

  1. Lightly re-dampen the area with cool water (do not soak).
  2. Apply your cleaning solution (such as diluted white vinegar).
  3. Let it sit for 10–15 minutes so it can reach deeper into the stain.
  4. Blot thoroughly to remove as much moisture as possible.
  5. Cover with baking soda and leave it for several hours.
  6. Vacuum and repeat if any odor or discoloration remains.

Some older stains may not disappear completely, but color and smell usually improve with one or more treatments.

Can I use bleach or harsh chemicals on a pee-stained mattress?

Generally, no. Bleach and strong chemicals can:

  • Damage mattress materials
  • Leave behind strong, persistent odors
  • Potentially discolor fabrics

Most mattresses respond better to milder solutions like diluted soap, vinegar, or cleaners labeled safe for household fabrics. Always test a small, hidden spot first if you’re unsure.

How do I get rid of the urine smell completely?

Odor comes from urine crystals that can linger inside the mattress. To reduce smell:

  • Use white vinegar solution to help break down odor-causing residues.
  • Apply a thick layer of baking soda and leave it for as long as possible (many people prefer overnight).
  • Make sure the mattress dries completely; trapped moisture can cause odors to return.

Persistent smells may need more than one cleaning round. If odor remains strongly after several attempts, some sleepers choose to use a mattress protector going forward to create a barrier over any remaining traces.

Is there a difference between cleaning child, pet, or adult urine?

The cleaning steps are largely the same:

  • Blot
  • Apply a gentle cleaner
  • Deodorize
  • Dry completely

However:

  • Pet urine can sometimes have a stronger smell and may penetrate more deeply. It may require repeated treatments for odor.
  • Large accidents (for example, if a large section of the mattress is soaked) may take longer to dry and may need more baking soda and blotting.

In all cases, avoid soaking the mattress heavily—more liquid is not always better.

How can I dry the mattress safely after cleaning?

Drying is a critical part of How To Clean Mattress That Has Been Peed On.

Helpful drying tips:

  • Place the mattress in a well-ventilated area.
  • Use a fan or gentle airflow directed at the cleaned spot.
  • If possible, place the mattress on its side so air can circulate around it.
  • Avoid using high heat directly on the mattress for long periods, as it may affect some materials.

Only put bedding back on when the mattress feels fully dry to the touch.

How do I prevent future accidents from ruining my mattress?

While accidents can’t always be avoided, you can limit the damage:

  • Use a water-resistant or waterproof mattress protector to create a barrier between liquids and the mattress.
  • Clean accidents as soon as you notice them, before they fully soak in and dry.
  • Keep extra bedding on hand so you can strip and replace it quickly at night.

These small steps can make future cleanups faster and help your mattress stay fresh longer.
