How To Wash a Memory Foam Mattress: Step‑by‑Step Care Guide

If you’re searching for “How To Wash a Memory Foam Mattress”, you’re likely dealing with spills, stains, or general freshness concerns. Memory foam needs more careful cleaning than a traditional spring mattress, but with the right approach you can keep it clean without damaging the foam.

Below is a clear FAQ-style guide on how to clean, deodorize, and protect a memory foam mattress safely.

Can You Wash a Memory Foam Mattress?

You cannot put a memory foam mattress in a washing machine, soak it in water, or hose it down. Memory foam acts like a sponge: it absorbs and holds water, which can lead to:

  • Long drying times
  • Unpleasant odors
  • Possible mold or mildew

Instead, when people ask How To Wash a Memory Foam Mattress, they are usually looking for surface cleaning, stain removal, and odor control using gentle, low‑moisture methods.

What’s the Safest Way To Clean a Memory Foam Mattress?

1. Start With Basic Surface Cleaning

  1. Strip the bed
    Remove all bedding, protectors, and covers that are washable. Wash those separately according to their care labels.

  2. Vacuum the mattress
    Use a hand vacuum or an upholstery attachment. Gently go over the entire surface, including seams and edges, to remove dust, hair, and crumbs.

  3. Spot clean only
    Focus any “washing” on specific stains or soiled areas, not the entire mattress.

How Do You Remove Spills and Stains From Memory Foam?

Spot-Cleaning Steps

When learning How To Wash a Memory Foam Mattress for a specific stain, the method is usually:

  1. Blot, don’t rub
    If the spill is fresh, press a clean, dry cloth or paper towel onto the area to soak up as much liquid as possible. Avoid rubbing, which can push liquid deeper into the foam.

  2. Use a mild cleaning solution
    Mix a small amount of gentle liquid detergent with cool or lukewarm water. Lightly dampen a clean cloth with the solution (do not soak the cloth).

  3. Gently treat the stain
    Dab the stain with the damp cloth, working from the outside inward. Use light pressure to avoid pushing moisture into the foam.

  4. Rinse with a clean damp cloth
    Dampen another cloth with plain water and blot the area to remove any soapy residue.

  5. Blot dry
    Use a dry towel to press and absorb as much moisture as possible.

🧼 Tip: Always test any cleaner on a small, hidden area first to check for discoloration.

How Do You Deodorize a Memory Foam Mattress?

If the mattress smells stale or musty:

  1. Vacuum first to remove debris.
  2. Lightly sprinkle baking soda over the entire surface.
  3. Let it sit for several hours, or longer if possible.
  4. Vacuum thoroughly to remove all baking soda.

Baking soda can help absorb odor and surface moisture without soaking the foam.

How Should You Dry a Memory Foam Mattress After Cleaning?

Proper drying is a crucial part of How To Wash a Memory Foam Mattress safely.

  • Let it air dry completely before putting bedding back on.
  • If possible, place the mattress in a well-ventilated room.
  • Use a fan to increase airflow and speed up drying.
  • Avoid direct, intense heat (like a hair dryer on high heat), which may damage the foam.

The mattress should feel completely dry to the touch across the cleaned area before you cover it again.

What Cleaning Products Should You Avoid?

To protect the foam structure, it’s best to avoid:

  • Harsh chemical cleaners
  • Strong solvents
  • Bleach or products with high bleach content
  • Steam cleaners (they introduce too much heat and moisture)

These can break down memory foam or affect its feel and durability. Mild detergent and water, used sparingly, are usually the safest option.

How Often Should You Clean a Memory Foam Mattress?

  • Vacuuming: Every few months, or whenever you rotate bedding.
  • Spot cleaning: As needed, immediately after any spill or visible stain.
  • Deodorizing with baking soda: Every few months, or when you notice lingering odors.

Many sleepers also use a washable mattress protector to help prevent stains from reaching the foam in the first place.

How To Protect a Memory Foam Mattress From Future Stains

While How To Wash a Memory Foam Mattress is important, prevention makes cleaning easier:

  • Use a water-resistant protector to guard against spills and sweat.
  • Let beverages and liquids stay off the bed when possible.
  • Rotate or reposition the mattress according to the manufacturer’s guidance to promote even wear.
  • Air out the mattress occasionally by pulling back bedding during the day.
