How To Clean The Mattress From Pee: Simple Steps That Actually Work

Accidents happen, whether it’s from a child, a pet, or a nighttime spill. If you’re searching for “How To Clean The Mattress From Pee”, you’re likely looking for a fast, clear method that removes the smell, stain, and dampness without ruining your mattress. This guide walks you through exactly what to do, what to avoid, and how to help prevent future issues.

What’s the Best First Step When There’s Fresh Pee on a Mattress?

Acting quickly makes a big difference. Fresh urine is much easier to remove than dried stains.

  1. Strip the bed immediately
    Remove sheets, mattress protector, and any blankets so the urine doesn’t spread. Wash fabrics according to their care labels.

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

    • Work from the outside of the stain inward.
    • Avoid scrubbing, which can push urine deeper into the mattress.

  3. Mix a gentle cleaning solution
    A common home solution is:

    • 1 part mild liquid detergent to 3–4 parts cool water
      Lightly dampen (not soak) a clean cloth with this mixture and gently dab the stained area.

  4. Rinse with a damp cloth
    Use another cloth with plain cool water to remove detergent residue. Too much soap left behind can attract dirt later.

  5. Absorb excess moisture
    Blot again with dry towels to remove as much liquid as possible before you move on to odor control and drying.

How Do I Remove Pee Smell From a Mattress?

Even after the visible stain is gone, odor can linger. To address smell:

  1. Use baking soda generously
    Sprinkle a thick, even layer of baking soda over the cleaned area. Baking soda is commonly used to absorb lingering odors from fabrics and soft surfaces.

  2. Let it sit for several hours
    Leaving it on at least 8 hours, or overnight, usually helps it work more effectively.

  3. Vacuum thoroughly
    Use the upholstery attachment to remove all the baking soda. Go over the area multiple times to pull powder out of the fabric and surface layers.

If odor remains, you can repeat the baking soda step again. Persistent smells may sometimes require multiple treatments.

How To Clean The Mattress From Pee Once It Has Dried?

Dried urine stains can be more stubborn, especially if they’ve been there for a while.

  1. Lightly re-dampen the area
    Use a spray bottle with cool water to lightly mist (not soak) the stained spot. This helps loosen the dried residue.

  2. Apply a gentle cleaning mixture
    You can use the same mild detergent-and-water solution, applied sparingly with a cloth. For older stains, some people also use a small amount of white vinegar mixed with water, but always:

    • Test a small, hidden area first to check for discoloration.
    • Avoid over-saturating the mattress.

  3. Blot repeatedly
    Alternate between applying solution and blotting with dry towels. The goal is to lift the stain out gradually, not to flood the mattress.

  4. Use baking soda afterward
    Once you’ve done your best at stain removal and blotting, cover the area with baking soda and let it sit before vacuuming. This step helps with both residual moisture and odor.

How Do I Dry the Mattress Safely After Cleaning Pee?

Drying thoroughly is essential to avoid lingering smells and damp spots.

  • Increase airflow: Open windows, use a fan, or direct a portable fan at the cleaned area.
  • Use natural warmth: If possible, let the mattress dry in a warm, dry room.
  • Avoid direct high heat: Direct, intense heat from hairdryers or heaters can sometimes damage mattress materials or covers.
  • Check before remaking the bed: Make sure the mattress is completely dry to the touch before putting sheets back on.

Drying can take several hours. Rushing this step can trap moisture inside.

Can I Use Any Cleaner on My Mattress?

Not every mattress material reacts the same way to liquids or cleaners.

  • Check your mattress care instructions: These often explain what types of cleaners and how much moisture are safe.
  • Avoid harsh chemicals: Strong bleach, heavy solvents, or highly concentrated cleaners can discolor fabric or damage foams.
  • Use minimal liquid: Mattresses are thick and slow to dry. Applying too much fluid can cause long-lasting dampness in deeper layers.

When in doubt, start with mild solutions and light applications rather than heavy soaking.

How Can I Prevent Pee From Reaching the Mattress Next Time?

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

  • Use a waterproof mattress protector to create a barrier between the sheets and the mattress.
  • Wash bedding promptly after any accident to reduce lingering smells.
  • Spot-check regularly for any missed stains, especially in homes with young children or pets.
