How To Clean a Memory Foam Mattress Topper: Simple Steps and FAQs

If you’re wondering how to clean a memory foam mattress topper without damaging it, you’re not alone. Memory foam is comfortable but delicate, and it doesn’t respond well to harsh scrubbing or soaking. This guide walks through practical, safe methods to keep your topper fresh, plus answers to the most common questions about stains, odors, and routine care.

What makes cleaning a memory foam topper different?

Memory foam is a dense, absorbent material designed to contour to your body. That same structure means it:

  • Holds onto moisture easily
  • Takes a long time to dry
  • Can be damaged by strong chemicals or rough handling

Because of this, you should never fully saturate or machine-wash a memory foam mattress topper. Instead, cleaning focuses on surface care, gentle spot treatment, and thorough drying.

Step-by-step: How To Clean a Memory Foam Mattress Topper

1. Start with basic surface cleaning

  1. Strip the bed
    Remove all sheets and mattress protectors.

  2. Vacuum the topper
    Use a vacuum with an upholstery attachment to remove dust, hair, and crumbs. Work in slow, overlapping passes on both sides.

  3. Air it out
    If possible, place the topper in a well-ventilated area. A few hours of fresh air can help reduce mild odors.

2. How do you spot clean stains on memory foam?

For small spills or stains, spot cleaning is the safest approach.

  1. Blot, don’t rub

    • Use a clean, dry cloth or paper towel to gently blot up as much liquid as possible.
    • Avoid pressing hard or scrubbing, which can push moisture deeper into the foam.

  2. Use a mild cleaning solution
    Mix a small amount of gentle liquid soap with cool water. Lightly dampen (don’t soak) a clean cloth with the solution.

  3. Gently dab the stain

    • Work from the outside of the stain toward the center.
    • Keep the topper as dry as you can; you only want the surface slightly damp.

  4. Rinse the area
    Dampen another cloth with plain water and blot the cleaned area to remove soap residue.

  5. Dry thoroughly

    • Blot with a dry towel to absorb moisture.
    • Allow the topper to air dry completely before putting bedding back on.

3. Can you deep clean or deodorize a memory foam topper?

Deep cleaning a memory foam topper still shouldn’t involve soaking it. Instead, focus on odor removal and gentle refreshers.

For general freshening and mild odors:

  • Lightly sprinkle baking soda over the surface
  • Let it sit for several hours (or overnight)
  • Vacuum thoroughly to remove the powder

For stronger odors, you can repeat this process on both sides.

4. How do you clean different types of stains?

Sweat or body oils

  • Use the mild soap-and-water solution described above.
  • For lingering odor, follow with a light dusting of baking soda once the area is dry.

Food or drink spills

  • Blot immediately.
  • Spot clean with mild soap and cool water.
  • Avoid hot water, which may set some stains.

Urine or similar accidents

  • Blot as much as possible right away.
  • Use a mild soap solution to clean the area.
  • After it dries, apply baking soda to help with remaining odor, then vacuum.

In all cases, avoid bleach and harsh chemicals, which can break down the foam and affect its feel.

❓ Common FAQs About How To Clean a Memory Foam Mattress Topper

Can I put a memory foam topper in the washing machine?

No. Machine washing can tear, deform, or saturate the foam, leading to permanent damage and long dry times. Memory foam toppers should be hand-cleaned only using surface and spot-clean methods.

Can I steam clean a memory foam topper?

Steam introduces a lot of heat and moisture, which can damage the foam or cause it to hold moisture deep inside. Steam cleaning is generally not recommended for memory foam.

How long does a topper take to dry?

Drying time depends on thickness, ventilation, and how wet it became. After spot cleaning:

  • Expect several hours to a full day of air-drying.
  • Speed drying by placing it in a well-ventilated, warm (not hot) area, preferably with a fan blowing gently over the surface.
  • Make sure the topper is completely dry before covering it again to avoid trapped moisture and musty odors.

How can I protect my memory foam topper in the future?

To reduce the need for deep cleaning:

  • Use a removable, washable mattress protector over the topper.
  • Wash your bedding regularly.
  • Vacuum the topper’s surface occasionally to control dust.
  • Address spills immediately to prevent them from soaking into the foam.

These habits can help your topper stay cleaner for longer and make spot cleaning easier when you need it.
