Can You Shampoo Memory Foam Mattress? Safe Cleaning FAQs Explained

If you’re wondering “Can You Shampoo Memory Foam Mattress?”, you’re not alone. Spills, stains, and smells can make anyone want to reach for a carpet or upholstery shampooer. But memory foam is a delicate material, and cleaning it the wrong way can cause lasting damage.

This FAQ-style guide walks through what you can and can’t do, and how to clean a memory foam mattress safely.

Can You Shampoo Memory Foam Mattress at All?

In general, you should not use a traditional shampoo machine or soak a memory foam mattress with shampoo and water.

Memory foam is a dense, absorbent material. When it takes in too much moisture:

  • It can break down or lose its supportive structure
  • It may trap water deep inside, making it hard to dry
  • Lingering moisture can lead to odors and other issues over time

So while the question “Can You Shampoo Memory Foam Mattress” comes up often, the safest answer is: avoid wet shampooing and soaking. Instead, use spot-cleaning and surface-safe methods.

Why Is Memory Foam So Sensitive to Shampoo and Water?

How Memory Foam Works

Memory foam is made from viscoelastic polyurethane foam, designed to respond to heat and pressure. This is what gives it that contouring, “hugging” feel many sleepers enjoy.

What Happens When It Gets Too Wet?

When you shampoo or heavily wet a memory foam mattress:

  • Foam cells can weaken and become crumbly over time
  • The mattress may take days to dry fully, if at all, especially in the center
  • Trapped moisture can cause persistent damp spots or smells

Because of this, most care instructions for memory foam recommend minimal moisture and no machine shampooing.

How Should You Clean a Memory Foam Mattress Instead?

Basic Routine Cleaning

For everyday care, focus on dry methods:

  • Vacuum the surface with a soft brush attachment to remove dust and debris
  • Use a mattress protector to prevent future stains and spills
  • Rotate the mattress periodically according to manufacturer guidance

These steps help you avoid needing heavy cleaning in the first place.

Spot-Cleaning Spills and Stains

If something spills on your bed:

  1. Act quickly

    • Blot (don’t rub) with a clean, dry cloth or paper towel to absorb as much liquid as possible.

  2. Use a mild cleaning solution

    • Mix a small amount of mild liquid soap with cool water.
    • Lightly dampen a cloth with this solution. Do not pour it directly on the mattress.

  3. Gently dab the stain

    • Work from the outside of the stain inward to avoid spreading it.
    • Keep the area as lightly damp as possible, not soaked.

  4. Rinse with a clean, slightly damp cloth

    • Remove soapy residue carefully.

  5. Dry thoroughly

    • Press with a dry towel to remove moisture.
    • Allow the mattress to air dry completely before putting sheets back on.
    • Good airflow and a fan can help; avoid direct high heat.

This approach avoids the problems that come with trying to shampoo memory foam mattress surfaces like you would a carpet or couch.

What About Odors? Do You Need Shampoo to Remove Them?

You usually don’t need shampoo to handle everyday mattress odors.

Simple Deodorizing Method

  • Sprinkle baking soda over the mattress surface
  • Let it sit for several hours (or longer if possible)
  • Vacuum thoroughly to remove the baking soda

Baking soda can help absorb odors without soaking the foam. This is often safer and more effective than using scented shampoos, which may leave residue and excess moisture.

Are Any Shampoo or Cleaning Products Safe for Memory Foam?

Some gentle, water-based cleaners may be safe in small amounts, but there are important guidelines:

  • Check the mattress care label first for manufacturer instructions
  • Avoid harsh chemicals, bleach, or strong solvents
  • Use very diluted solutions and apply them sparingly with a cloth, not directly onto the foam
  • Always test on a small, hidden area first

The key is: no soaking, no scrubbing with lots of liquid, and no machine-style shampooing.

How Do You Dry a Memory Foam Mattress Safely?

Drying is just as important as cleaning:

  • Place the mattress in a well-ventilated area
  • Use a fan to move air across the surface
  • If possible, place it so that air can circulate around it (for example, on a breathable bed base)
  • Avoid placing it in direct, intense sunlight or using high heat devices for long periods

Never put sheets back on or sleep on the mattress until it feels completely dry to the touch.
