How to Clean Foam Mattress

We spend a third of our lives in bed. A clean foam mattress means better sleep and fewer allergens. Here's how to clean yours.

What You'll Need

  • Vacuum with upholstery attachment
  • Baking soda
  • Mild dish soap
  • Spray bottle
  • Clean towels
  • White vinegar (for stains)

Step-by-Step Instructions

  1. 1

    Strip the bed

    Remove all sheets, mattress protectors, and toppers. Wash bedding in hot water during the cleaning process.

  2. 2

    Vacuum the entire surface

    Vacuum the top, sides, and bottom of the foam mattress with the upholstery attachment to remove dust mites, hair, and debris.

  3. 3

    Sprinkle with baking soda

    Sprinkle a generous layer of baking soda over the entire mattress. Let it sit for at least 1 hour (or up to 24 hours) to absorb odors and moisture.

  4. 4

    Vacuum the baking soda

    Vacuum up all the baking soda thoroughly. The longer it sits, the more odors it absorbs.

  5. 5

    Spot clean stains

    Mix a few drops of dish soap with cool water. Dampen a cloth and gently dab stains -- never soak foam. Blot with a dry towel and air dry.

Pro Tips

  • TIPFoam mattresses cannot be deep cleaned with steam or wet methods -- water destroys the foam structure.
  • TIPAlways use a waterproof mattress protector to prevent stains and extend the mattress life dramatically.
  • TIPRotate or flip the mattress every 3-6 months (if the manufacturer allows) to even out wear.

Common Mistakes to Avoid

  • XSaturating foam with water or cleaner, which destroys the cell structure and causes permanent damage.
  • XUsing a steam cleaner, which over-saturates the foam and breaks down the materials.
  • XSkipping the vacuum step, which leaves dust mites and allergens in the foam.

Frequently Asked Questions

No. Steam cleaning over-saturates the foam and damages its structure. Spot clean only with minimal moisture.
