How To Clean Mattress Stain: Simple Steps That Actually Work

Spot a fresh spill or discover an old mark on your bed and wondering how to clean mattress stain safely and effectively? This guide walks through what to do, what to avoid, and how to handle different types of stains without damaging your mattress.

What’s the Best Way To Clean a Mattress Stain?

The best approach to how to clean mattress stain is to:

  1. Act quickly when possible
  2. Blot, don’t scrub
  3. Use a mild cleaning solution suited to the type of stain
  4. Let the mattress dry completely before making the bed

A simple starting method for many stains:

  • Mix a small amount of mild liquid soap with cool water
  • Lightly dampen a clean cloth, then blot the stain from the outside in
  • Use another clean cloth with plain water to remove soapy residue
  • Blot dry with a towel and air-dry fully

How Do I Clean Fresh vs. Old Mattress Stains?

Fresh Stains

Fresh stains are usually easier to remove.

  1. Blot immediately with a dry towel or paper towels
  2. Avoid rubbing, which can push the stain deeper
  3. Apply a gentle cleaning solution, then blot again
  4. Use a dry towel to soak up excess moisture

Old or Set-In Stains

Older stains may need more time and repeated treatments.

  • Lightly mist the area with water first to re-soften the stain
  • Apply your chosen cleaner and let it sit for 10–15 minutes
  • Blot, then repeat as needed rather than soaking the mattress

How To Clean Mattress Stain by Type

Different stains respond best to slightly different methods. Always spot-test in a small hidden area first to check for discoloration.

How To Clean Mattress Stain from Sweat

Sweat can leave yellowish marks and odors over time.

  • Mix water and a small amount of mild soap
  • Lightly dab the stain with a cloth
  • For lingering discoloration, a small amount of baking soda sprinkled on the area can help absorb moisture and odor—vacuum once dry

How To Clean Mattress Stain from Urine

Urine is common on children’s mattresses and needs gentle but thorough care.

  1. Blot as much liquid as possible with towels
  2. Mix cool water with a little mild soap
  3. Dab the area, then blot dry
  4. Sprinkle baking soda over the damp area and leave it several hours
  5. Vacuum up the baking soda once fully dry

How To Clean Mattress Stain from Blood

Use cool water only; warm or hot water may set blood stains.

  • Dab with a cloth dipped in cool, slightly soapy water
  • Blot repeatedly; avoid drenching the mattress
  • For stubborn marks, repeated gentle treatments are often more effective than one heavy application

What Cleaning Products Are Safe for Mattresses?

Most mattresses respond best to mild, low-moisture cleaning:

  • Mild liquid soap diluted with water
  • Baking soda to absorb moisture and odor
  • Very light use of household stain removers that are safe for fabrics (spot-test first)

Avoid:

  • Strong bleach on the entire mattress surface
  • Saturating the mattress with large amounts of liquid
  • Harsh scrubbing tools that can damage the cover

How Do I Dry the Mattress After Cleaning?

Drying is just as important as stain removal. A damp mattress can feel uncomfortable and may develop odors.

  • Press a clean, dry towel on the area to remove as much moisture as possible
  • If possible, open windows or use a fan to increase airflow
  • Allow several hours of drying time before replacing bed sheets
  • Avoid putting the mattress in direct, intense heat sources that could damage materials

How Can I Prevent Mattress Stains in the Future?

You can’t avoid every spill, but some simple habits help:

  • Use a removable, washable mattress protector
  • Clean up spills and accidents right away
  • Air out your mattress occasionally by removing bedding and allowing fresh air to circulate
