How To Get Pee Stains Out Of Mattresses: Simple Steps That Actually Help

If you’re searching for “How To Get Pee Stains Out Of Mattresses,” you’re likely dealing with a fresh accident or a lingering stain and smell. This guide walks you through what to do right away, how to treat older stains, and what to avoid so you don’t damage your mattress.

What Happens When Pee Gets on a Mattress?

Urine is a mix of water, salts, and waste products. On a mattress, that can mean:

  • Visible yellow stains
  • Lingering odor, especially with older or repeated accidents
  • Deeper penetration into foam or padding if not cleaned quickly

Because mattresses are thick and absorbent, the sooner you act, the better your chances of removing both the stain and the smell.

How To Get Pee Stains Out Of Mattresses: Step-by-Step for Fresh Accidents

1. Blot, Don’t Rub

  • Remove bedding right away.
  • Use clean, dry towels or paper towels to blot up as much liquid as possible.
  • Press firmly; avoid scrubbing, which can push urine deeper into the mattress.

2. Apply a Gentle Cleaning Solution

A simple at-home method many people use:

  1. Mix:
    • 1 part white vinegar
    • 1 part cool water
  2. Lightly spray or dab the solution onto the stained area until it’s damp, not soaking.
  3. Let it sit for 5–10 minutes to help break down the stain and odor.
  4. Blot again thoroughly with clean towels.

Vinegar is commonly used because it can help neutralize odors and loosen residue without harsh chemicals.

3. Use Baking Soda to Deodorize

  • Sprinkle a generous layer of baking soda over the damp area.
  • Gently spread it out; you want a visible coating.
  • Leave it on for several hours, or ideally overnight, to absorb moisture and odor.
  • Vacuum the baking soda thoroughly.

If the stain or smell remains, you can repeat the process once or twice.

How Do You Remove Dried or Old Pee Stains?

Older stains can be more stubborn, but you can still improve them.

1. Lightly Re-Dampen the Area

  • Use a spray bottle with plain water or a mild vinegar-and-water mix.
  • Slightly dampen the stained area to help loosen dried residue. Avoid soaking.

2. Use a Stronger Cleaning Mix

Some people find this mix helpful for older, set-in stains:

  • 1 cup hydrogen peroxide (3% strength)
  • 1–2 tablespoons baking soda
  • A small amount of mild liquid soap

Stir gently and test a little on a hidden area first to check for discoloration. If it looks fine after drying:

  1. Lightly apply the mixture to the stain.
  2. Let it sit and dry completely (this can take several hours).
  3. Once dry, vacuum any powdery residue.

⚠️ Important: This method may lighten fabrics or mattress covers, especially darker ones. Always spot-test first.

Can You Remove the Smell Completely?

Odor depends on:

  • How quickly you treat the accident
  • How much urine soaked in
  • Mattress materials and thickness

For many people, a combination of vinegar solution plus baking soda significantly reduces or removes the smell. For persistent odor:

  • Repeat the cleaning process.
  • Allow the mattress to air out in a well-ventilated room.
  • If possible, place it in indirect sunlight for a few hours; many find this helps freshen fabric.

Odor may fade gradually over time even after cleaning.

What Should You Avoid When Cleaning Pee from a Mattress?

To protect your mattress:

  • Don’t use very hot water – it may set the stain.
  • Don’t saturate the mattress – excess liquid can sink deep and be hard to dry.
  • Avoid harsh bleach on most mattress fabrics – it can discolor and weaken materials.
  • Don’t skip drying time – a damp mattress can develop musty smells.

Aim for light, controlled moisture and thorough drying.

How Long Does It Take for a Mattress to Dry?

Drying time depends on room temperature, humidity, and how much liquid was used. As a general guideline:

  • Expect at least several hours for surface dryness.
  • For deeper areas, many people allow a full day before making the bed again.
  • Use fans, open windows, or a dehumidifier to speed up drying.
  • Ensure the mattress feels completely dry to the touch before adding sheets.

How Can You Prevent Future Pee Stains?

While accidents happen, a few habits can make them less stressful:

  • Use a waterproof mattress protector to create a barrier.
  • For children or pets, consider washable mattress pads on top.
  • Clean accidents as soon as you notice them for the best outcome.
  • Keep basic cleaning supplies (vinegar, baking soda, clean cloths) ready.

Prevention often turns a major cleanup into a minor inconvenience.
