How to Clean Memory Foam Mattress

Do you consider your mattress your best friend after a long day? It can’t comfort you if it hasn’t been cleaned in a while. The good news is that keeping a memory foam mattress fresh is more straightforward than it seems once you know the proper steps. This guide explains how to clean memory foam mattresses safely and effectively — including an innovative, low-odour approach that pairs vinegar (to dissolve residues) with baking soda (to neutralise odours) without soaking the foam.

Tip 1: Read the Care Instructions

Even though most memory foam mattresses follow similar guidelines, manufacturers sometimes provide additional information about approved cleaners, drying times, or covers. Before you strip the bed, check the label or care guide — a few seconds here can save you hassle later.

Tip 2: Vacuum Your Mattress Every Week

Weekly vacuuming won’t remove stains, but it will reduce dust, skin cells and debris that make deep cleans harder. Use the upholstery brush and make slow passes, focusing on seams and any quilting where dirt, hair, or dust mites tend to accumulate. Swap the sheets while you’re at it for that entirely fresh feel.

Tip 3: Consider Using Baking Soda on Your Mattress

For odours or light mustiness, sprinkle a fine, even layer of baking soda over the bare mattress (think “light dusting of snow”). Leave for up to 12 hours to absorb moisture and smells, then vacuum thoroughly. Repeat monthly or after any spill to keep the surface inviting.

Tip 4: Clean Any Stains Straight Away With Mild Soap and Water

Fresh spills are far easier to remove. Blot with a white towel to lift liquid (don’t rub — that drives stains deeper). Mix a small amount of mild soap with cool water in a spray bottle. Lightly mist the spot, then blot it dry and repeat the process until the area is clear. Finish by blotting with a dry towel and let the mattress air-dry completely before making the bed.

Tip 5: Apply Mild Detergent to Old and Tough Stains

For set stains (e.g., dried sweat, food, or blood), apply a solution of cool water and a small amount of mild detergent. Mist, blot, and repeat. If traces remain, try this pH-smart duo: mix three tablespoons of baking soda with one cup of white vinegar in a spray bottle. Apply, allow a short dwell time, then blot. A soft toothbrush can help on stubborn edges — be gentle to avoid abrading the foam.

Tip 6: Try a Solution of Vinegar, Detergent, and Water

For food and drink spills (such as coffee, tomato, or fruit), combine cool water with a dash of laundry detergent and a little vinegar. Mist until the stain is evenly damp (not soaked), wait ~15 minutes, then blot with a wet towel. Repeat as needed. Finish with a plain-water mist and a dry towel to lift any residue. Air-dry thoroughly with a fan; if using a hair dryer, stick to no-heat/low to protect the foam.

FAQ

What are some dos and don’ts of cleaning memory foam mattresses?

Here’s everything you should and shouldn’t do when it comes to cleaning a memory foam mattress:

• Do: Use a mattress protector or topper to prevent spills from reaching the foam.
• Don’t: Oversaturate — excess water can damage the core and prolong odours.
• Do: Vacuum and spot clean regularly to extend the lifespan.
• Don’t: Use harsh chemicals or steam cleaners; heat and strong solvents can damage the foam.

Is it okay to wash a memory foam pillow in the washing machine?

No. Machine washing can break down the structure and deform the pillow. Remove and wash the cover only, and spot-clean the foam using the same light-mist, blot-dry approach described above.

The Bottom Line

Now that you know the correct way to clean memory foam mattresses, you can tackle routine care with confidence. Vacuum regularly, deodorise with baking soda, and spot-clean using mild soap – or a clever pairing of diluted vinegar followed by baking soda for odour control – while keeping moisture to a minimum.
