How to Clean Memory Foam Pillows Without Damaging Them

Posted on by Palla Decor

How to Clean Memory Foam Pillows the right way is essential if you want to maintain both hygiene and long-lasting comfort. While these pillows provide excellent support for quality sleep, they tend to trap sweat, dust, and odors over time. Unlike regular pillows, memory foam can’t simply be tossed into the washer—doing so may damage its structure. This guide will show you exactly how to clean memory foam pillows safely at home, using simple yet effective methods to keep them fresh, supportive, and like new.

Can You Wash Memory Foam Pillows?

No, you should not wash memory foam pillows in a washing machine. The agitation from the machine and the heat from the dryer can break apart the delicate foam, causing irreversible damage. Instead, memory foam pillows should be either hand washed or spot cleaned, depending on the level of dirt or staining.

How to Hand Wash Memory Foam Pillows (Deep Clean)

If your pillow is due for a thorough clean, follow these steps:

Materials Needed:

  • Mild detergent (no bleach or harsh chemicals)
  • Bathtub or large basin
  • Clean towels
  • Fan (optional for faster drying)

Step-by-Step Guide:

  1. Remove the pillow cover and wash it separately according to the care label. Most covers are machine-washable.
  2. Fill a bathtub or sink with lukewarm water. Add a small amount (about 1 teaspoon per gallon) of gentle detergent.
  3. Submerge the pillow fully into the water. Gently squeeze and massage it to allow the detergent to penetrate and lift dirt.
  4. Rinse thoroughly with clean water until there are no soap suds left.
  5. Squeeze out excess water by pressing (not twisting or wringing) the pillow.
  6. Lay flat to dry on a clean towel in a well-ventilated area. Avoid direct sunlight and never use a dryer.
  7. Allow 24–48 hours to fully dry, depending on humidity levels.
Pro Tip: Use a fan to speed up the drying process. A completely dry pillow is crucial to prevent mold and odor.

How to Spot Clean Memory Foam Pillows

For minor stains or in-between washes, spot cleaning is your go-to method.

Materials Needed:

  • Mild detergent or dish soap
  • Lukewarm water
  • White clean cloth or sponge
  • Towel or paper towels

Instructions:

  1. Mix solution: In a bowl, combine 1 tablespoon of mild detergent with 2 cups of lukewarm water.
  2. Dab the stain: Dip a clean cloth into the solution and gently blot the stained area from the outside in.
  3. Blot with clean water: Use another cloth dipped in clean water to remove detergent residue.
  4. Dry thoroughly: Pat the area with a dry towel, then air-dry completely. A fan or cool-setting hair dryer can speed this up.

  • If your pillow smells a little musty:
  • Sprinkle baking soda evenly over the surface.
  • Let it sit for 8–12 hours.

FAQ – Memory Foam Pillow Cleaning (Expanded)

Can memory foam pillows go in the washing machine?

No. Washing machines can tear or break memory foam apart. The spinning motion and heat from dryers are too harsh. Stick to hand washing or spot cleaning only.

Can you dry a memory foam pillow with a hair dryer?

Yes, but only on the cool or low setting. High heat can cause foam to crack. It’s best to air dry in a well-ventilated space and use a fan if needed.

How do I get rid of yellow stains on my pillow?

Yellow stains are usually from sweat and body oils. Mix water and white vinegar (1:1), dab the stain with a cloth, then blot with clean water and let air dry. Avoid over-wetting the foam.

Why does my memory foam pillow smell bad?

It could be from sweat, moisture buildup, or poor ventilation. Deodorize using baking soda and ensure it’s fully dry before use. Always store in a dry, cool area.

Can I use disinfectant spray on memory foam?

Use it sparingly. Light misting with fabric-safe disinfectant can be done, but overuse might saturate the foam. It’s better to rely on regular spot cleaning and pillow protectors.
