How Do You Clean a Memory Foam Mattress? A Simple, Step‑by‑Step Guide

If you’re wondering “How do you clean a memory foam mattress?”, you’re not alone. Memory foam feels great to sleep on, but it needs a bit of special care. This guide walks you through safe cleaning methods, answers common questions, and clears up myths about what you can and can’t use on memory foam.

What Makes Cleaning a Memory Foam Mattress Different?

Memory foam is a dense, absorbent material that holds its shape and slowly responds to pressure. This is what gives it that contouring feel many sleepers enjoy.

Because of this:

You should avoid soaking it with water — it can be hard to dry and may trap moisture.
Harsh chemicals can damage the foam, break down its structure, or leave strong odors.
Scrubbing too hard can tear or crumble the foam’s surface.

Understanding these basics helps you choose cleaning methods that are gentle but effective.

How Do You Clean a Memory Foam Mattress: Basic Routine Cleaning

Step 1: Strip the bed

Remove all sheets, covers, and protectors so the surface is fully exposed. Wash bedding according to label instructions.

Step 2: Vacuum the surface

Use a vacuum with an upholstery attachment to remove dust, hair, and crumbs.

Move slowly across the mattress.
Pay extra attention to seams and tufted areas.

This simple step helps keep your mattress fresher between deeper cleanings.

Step 3: Deodorize with baking soda (optional)

Lightly sprinkle dry baking soda over the surface and let it sit for a few hours.

Baking soda can help absorb mild odors and moisture.
Afterward, vacuum thoroughly to remove all powder.

Avoid mixing baking soda with liquids directly on the mattress; keep it dry.

How Do You Clean a Memory Foam Mattress with Spills or Stains?

Accidents happen. When they do, acting quickly is important.

Step 1: Blot, don’t scrub

Use a clean, dry cloth or paper towel to gently blot the spill.

Press down to absorb as much liquid as possible.
Do not rub or scrub — this can push moisture deeper into the foam.

Step 2: Use a mild cleaning solution

For many stains, a gentle solution is enough:

Mix a small amount of mild liquid detergent with cool water.
Lightly dampen (do not soak) a clean cloth with the solution.
Gently dab the stained area, working from the outside inward.

For tougher stains like sweat or light organic spills, some people use a very diluted vinegar-and-water mixture or a mild enzyme-based cleaner designed for fabrics. Always:

Test on a small, hidden area first.
Avoid over-wetting the mattress.

Step 3: Blot with plain water

After spot cleaning:

Dampen another cloth with clean water only.
Blot the area to help lift any leftover cleaner.
Follow with a dry cloth to remove excess moisture.

How Do You Clean a Memory Foam Mattress Safely Without Damaging It?

What should you avoid?

To protect your mattress:

Do not steam clean – heat and moisture can damage memory foam.
Do not use bleach or strong solvents – they can break down foam and discolor the surface.
Do not saturate with water – deep moisture is difficult to dry and can lead to long-lasting dampness.
Do not scrub vigorously – this can tear the foam.

How do you dry it properly?

After any cleaning:

Let the mattress air dry completely before putting bedding back on.
If possible, place it in a well-ventilated room.
You can use a fan pointed across (not pressed against) the surface to speed up drying.
Avoid direct, intense heat such as hair dryers on high heat.

The key is to make sure no dampness remains deep inside the foam.

How Often Should You Clean a Memory Foam Mattress?

Regular care can help your mattress feel fresher over time.

Vacuum: Every 1–3 months, or more often if you have pets.
Spot clean: Whenever spills or visible stains occur.
Deodorize with baking soda: A few times a year, or as needed.

Using a removable, washable mattress protector can also help reduce how often you need to deep clean the foam itself.

Common Questions About Memory Foam Mattress Cleaning

Can you use a carpet cleaner or upholstery machine?

It’s generally not recommended to use machines that spray water or cleaning solution directly into the mattress. Memory foam is not designed to be saturated and may not dry properly.

Can you flip or rotate the mattress after cleaning?

If your mattress is one-sided, you usually should not flip it, but rotating it 180 degrees from head to foot (when fully dry) is often helpful to even out wear. Always check the manufacturer’s care guidelines.

What if odors remain after cleaning?

If odors linger:

Allow extra air drying time.
Sprinkle a light layer of dry baking soda, let it sit several hours, then vacuum.
Ensure the room is well ventilated for a longer period.

Persistent or unusual smells may be a sign that the mattress is holding moisture or is aging, rather than just a surface cleanliness issue.
