How To Get Pee Stain Off a Mattress: Simple Steps That Actually Help

If you’re searching for “How To Get Pee Stain Off a Mattress”, you’re likely dealing with a fresh accident or an older yellow stain that just won’t fade. This guide walks you through what to do right away, how to treat dried stains and odor, and what to avoid so you don’t damage your mattress.

Why Do Pee Stains Stick to a Mattress?

Urine contains water, salts, and organic compounds. When it soaks into a mattress and dries, it can leave behind:

  • Yellow or darker stains
  • Lingering odor, especially when the room is warm or humid

Mattress covers and sheets can help, but they don’t always catch everything. Knowing how to get pee stain off a mattress quickly can reduce discoloration and keep smells from setting in.

What Should I Do Immediately After a Fresh Accident?

Acting fast makes a big difference.

  1. Strip the bed
    Remove all bedding and any mattress protectors so you can reach the stain directly.

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

    • Rubbing can spread the stain deeper and wider.
    • Keep blotting until the area feels only slightly damp.

  3. Apply a gentle cleaning solution
    A common option is a mix of mild dish soap and cool water. Lightly dab or spray it on the stained area, then blot again. Avoid soaking the mattress.

  4. Dry thoroughly
    Use a fan or open windows to increase airflow. The goal is for the mattress to dry all the way through, not just on the surface.

How To Get Pee Stain Off a Mattress (Dried or Old Stains)

When urine has already dried, you often have to tackle both the stain and the smell.

Step-by-step approach

  1. Lightly re-dampen the stain
    Use a small amount of cool water on a cloth and gently dab the stained area. This can help loosen dried residue.

  2. Apply a stain-fighting solution
    Common at-home options include:

    • Mild soap and water mixtures
    • Gentle, non-bleaching upholstery or fabric cleaners (used according to their directions)

    Test any cleaner on a small, hidden spot first to check for discoloration.

  3. Blot repeatedly
    Press with clean, dry cloths to pull moisture and residue out of the mattress. Rotate to fresh parts of the cloth as they get damp.

  4. Deodorize the area
    After cleaning, many people sprinkle dry baking soda over the area to help absorb remaining moisture and odor. Let it sit for several hours, then vacuum it up.

  5. Repeat if needed
    Older stains may need multiple gentle treatments rather than one harsh one.

How Can I Remove the Smell as Well as the Stain?

Even when the stain fades, a slight ammonia-like odor can remain.

  • Make sure the mattress is completely dry inside, not just on the surface.
  • Use good airflow: fans, open windows, or a well-ventilated room.
  • Some people find it helpful to:
    • Sprinkle baking soda over a wider area around the stain
    • Let it sit overnight
    • Vacuum thoroughly the next day

If the smell is still strong after careful cleaning and drying, it may have soaked deeply into the mattress. In those cases, the stain and odor may not disappear completely.

What Should I Avoid When Cleaning Pee Off a Mattress?

Using the wrong methods can cause more harm than the stain itself.

🚫 Avoid:

  • Soaking the mattress with a lot of water or cleaner
    • This can trap moisture inside and be slow to dry.
  • Harsh chemicals or strong bleaches
    • These can discolor fabric and damage materials.
  • Scrubbing aggressively
    • This can push the stain deeper and rough up the surface.
  • High heat while still wet
    • Applying strong direct heat (like very hot air) to a damp mattress may not be ideal and can make odors harder to shift.

Can All Pee Stains Be Removed Completely?

Not always. Many fresh stains respond well to quick blotting and gentle cleaning. Older, set-in stains can be more stubborn:

  • Color may lighten but not vanish.
  • Odor may linger slightly, especially inside the mattress core.

If the stain covers a large area, has been there for a long time, or the mattress has been repeatedly soaked, it may be difficult to restore it fully, even with careful cleaning.

How Can I Prevent Future Pee Stains on My Mattress?

While accidents can’t always be avoided, you can reduce long-term damage:

  • Use a washable, waterproof mattress protector.
  • Wash bedding promptly after accidents.
  • Allow the mattress to dry completely after any cleaning before remaking the bed.

These steps won’t stop spills from happening, but they can make cleaning faster and help keep your mattress in better shape over time.
