How To Clean Pee Stains On Mattress: Simple Steps That Actually Work

If you’re searching for “How To Clean Pee Stains On Mattress”, you’re likely dealing with a fresh accident or trying to remove an older, lingering stain. This guide walks you through what to do, what to avoid, and how to reduce odor so your mattress feels clean and comfortable again.

What Happens When Pee Soaks Into a Mattress?

Urine can seep deep into mattress layers. This often leads to:

  • Visible stains that may turn yellow over time
  • Lingering odors, especially in warm or humid rooms
  • Possible buildup of residue if not cleaned properly

Because most mattresses can’t be machine washed, knowing how to clean pee stains on mattress surfaces by hand is essential for keeping your sleep space fresh.

How To Clean Fresh Pee Stains on a Mattress

The sooner you act, the easier it usually is to remove both the stain and the smell.

Step 1: Blot, Don’t Rub

  1. Strip all bedding and wash separately.
  2. Use clean, dry towels or paper towels to blot up as much liquid as possible.
  3. Press firmly to absorb; avoid rubbing, which can push urine deeper into the mattress.

Step 2: Apply a Gentle Cleaning Solution

A simple approach many people use at home:

  • Mix mild liquid detergent with cool water.
  • Lightly dampen (not soak) a clean cloth with the solution.
  • Gently dab the stained area, working from the outside toward the center.

Keeping moisture to a minimum helps the mattress dry faster and reduces the chance of lingering dampness.

Step 3: Rinse & Blot Again

  • Use another cloth lightly dampened with plain water to remove soap residue.
  • Blot dry with a towel until the area feels only slightly damp.

How To Clean Pee Stains on Mattress That Have Dried

Dried stains can be more stubborn and may come with a stronger odor.

Step 1: Lightly Rehydrate the Stain

  • Lightly mist the area with cool water using a spray bottle (if available).
  • Do not saturate the mattress; a light mist helps loosen dried residue.

Step 2: Use a Targeted Cleaning Mix

Common household options include:

  • Mild detergent + water for general cleaning
  • White vinegar + water (equal parts) used sparingly for odor control

Test any solution on a small, hidden area first to check for discoloration. Then:

  1. Spray or dab the solution onto the stain.
  2. Let it sit for about 5–10 minutes.
  3. Blot with a dry towel until you lift as much moisture and discoloration as possible.

Step 3: Deodorize the Area

Many people find baking soda useful for absorbing odor:

  1. Sprinkle a thin, even layer over the damp area.
  2. Leave it for several hours, or ideally overnight.
  3. Vacuum thoroughly to remove the baking soda.

Will the Pee Smell Go Away Completely?

Odor reduction depends on:

  • How quickly you treat the stain
  • How deeply the urine soaked into the mattress
  • How much cleaner or water was used (more liquid can spread the stain)

Repeated, gentle treatments may be needed for stubborn odors. Avoid strong perfumes or heavy fragrances that simply mask the smell; they can mix with the odor and feel unpleasant over time.

Can You Use Bleach or Harsh Chemicals on a Mattress?

Generally, it’s best to avoid bleach and very strong cleaners on mattresses because:

  • They can damage or discolor mattress fabrics and foams.
  • Some may leave behind strong, lingering smells.

Instead, focus on mild, fabric-safe cleaners and gentle methods. Always follow any cleaning information provided with your mattress.

How Long Does It Take a Mattress to Dry After Cleaning?

Drying time varies, but most people find it helps to:

  • Open windows or increase airflow
  • Use a fan pointed at the cleaned area
  • Avoid making the bed until the mattress feels completely dry

A mattress that stays damp for long periods may develop an unpleasant smell, so ensure the area is fully dry before replacing bedding.

How To Prevent Future Pee Stains on a Mattress

While accidents can’t always be avoided, you can reduce their impact:

  • Use a water-resistant mattress protector.
  • Clean up spills and accidents as soon as possible.
  • Keep removable, washable covers on pillows and toppers where appropriate.

Adding this extra layer often makes cleaning much easier next time.
