How To Clean Pee Of a Mattress: Step‑By‑Step Guide and Common Questions

If you’re searching for How To Clean Pee Of a Mattress, you’re likely dealing with a fresh accident or a lingering urine stain. This guide walks you through simple, effective methods to remove the smell, stain, and moisture from your mattress, using common household items and clear steps.

What Happens When Pee Soaks Into a Mattress?

Urine is a liquid that can soak deep into foam and fabric, especially if not cleaned quickly. It can leave:

  • Visible stains
  • Odors that get stronger with warmth or humidity
  • A damp area that may take a long time to dry on its own

Addressing it properly helps your mattress stay more comfortable and usable for longer.

How To Clean Pee Of a Mattress (Fresh Accident)

1. Act fast and blot, don’t rub

  1. Strip all bedding and wash it separately.
  2. Use clean, absorbent towels or paper towels to blot the area.
  3. Press down firmly to soak up as much liquid as possible.
    • Avoid rubbing, which can push urine deeper into the mattress.

2. Apply a gentle cleaning solution

A simple mixture many people use:

  • 1 part white vinegar
  • 2 parts cool water

Lightly spray or dab the solution over the stained area until it’s damp, not soaked. Vinegar helps neutralize odor and break down the urine.

  • Let it sit for about 10–15 minutes.
  • Blot again with dry towels to remove excess moisture.

3. Use baking soda to absorb odor and moisture

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

  • Gently pat it to help it contact the surface.
  • Leave it on for at least 8 hours, or overnight if possible.

Baking soda helps draw out remaining moisture and reduces odor.

4. Vacuum thoroughly

Once the baking soda is completely dry:

  • Use a vacuum with an upholstery attachment.
  • Vacuum slowly to remove all the powder and any lifted residue.

If the stain or odor remains, you can repeat the process once more.

How Do I Clean Dried or Old Pee Stains From a Mattress?

Dried urine is more stubborn because it has had time to set into the fibers.

1. Lightly rehydrate the stain

Spray a mix of:

  • 1 part white vinegar
  • 1–2 parts cool water

onto the stained area until it’s slightly damp. This can help loosen dried residue.

2. Add baking soda and let it sit longer

Sprinkle baking soda over the dampened stain.

  • For old stains, leaving it for 12–24 hours can be helpful.
  • Once dry, vacuum thoroughly.

3. Repeat if needed

Old stains may need multiple rounds of treatment. If the mattress still has a strong smell after several attempts, some people consider designating that side as the non-sleep side or using a thick, washable mattress protector on top.

Is It Safe To Use Bleach or Harsh Cleaners?

Most mattress care instructions do not recommend bleach or very harsh chemicals because they can:

  • Damage mattress fabrics or foam
  • Leave their own strong odors
  • Lighten or discolor the surface

If you choose to use a stronger store-bought cleaner, always:

  • Spot-test a small, hidden area first
  • Follow the directions on the product label
  • Avoid oversaturating the mattress

How Can I Dry the Mattress Faster After Cleaning?

A mattress that stays wet too long can develop an unpleasant smell.

Helpful drying tips:

  • Open windows for fresh airflow
  • Use a fan aimed at the damp area
  • If available, use gentle indirect sunlight for a few hours

Avoid using very high heat directly on the mattress, as that may affect some materials.

How Can I Prevent Future Pee Stains on My Mattress?

Once you’ve figured out How To Clean Pee Of a Mattress, prevention becomes a priority.

Many people find it useful to:

  • Use a waterproof mattress protector
  • Add a washable mattress topper for an extra barrier
  • Wash bedding promptly after any future accidents

These steps make cleanup much easier if another accident happens.
