To clean a memory foam mattress properly, you should vacuum it thoroughly, treat odors with baking soda, spot clean stains with a tiny amount of gentle cleaner and water, then let it air dry completely. You should never soak memory foam, put it in a washing machine, or use harsh heat, because the foam acts like a sponge and will trap moisture and break down.
In this guide you will learn the exact order to do each step, what tools and cleaners are safe for memory foam, and how to prevent future buildup. You will also see how to handle common spills and smells without damaging your bed, and explore our mattresses guide for care tips that extend mattress life.
How to Clean a Memory Foam Mattress Step by Step Without Damaging It
1. Strip the Bed and Vacuum Every Surface
Remove all bedding, toppers, and protectors and wash them separately on a gentle, warm cycle. Vacuum the entire mattress surface, sides, and seams with an upholstery attachment to lift dust, hair, crumbs, and dust mites that settle deep in the texture.
Pay extra attention to tufts, zippers, and edges where debris collects, and use a crevice tool for seams. If you have a removable cover that is marked machine washable, wash it according to its label, otherwise just vacuum it and spot clean the cover itself.
2. Freshen and Deodorize With Baking Soda
Sprinkle a light, even layer of plain baking soda over the whole surface to absorb odors and light moisture. Let it sit for at least 30 minutes, or up to 8 hours for stronger odors, while you ventilate the room with open windows or a fan.
Vacuum the baking soda away completely with the upholstery tool, making two slow passes to ensure no powder remains. For a fresher finish between deep cleans, you can pair this step with breathable sheets for hot sleepers that help reduce sweat buildup.
3. Spot Clean Stains With Minimal Moisture
Mix a small amount of mild dish soap or enzyme cleaner with cool water, then lightly dampen a clean white cloth, not the mattress itself. Blot the stain from the outside inward, never scrub or saturate, because scrubbing can push the stain deeper and tear delicate foam cells.
After blotting, dab with a separate cloth lightly moistened with plain water to remove any soap residue, then blot dry with a towel. For urine, sweat, or other organic stains, an enzyme based formula works better than harsh bleach or ammonia, which can discolor and degrade memory foam.
4. Dry Completely With Air, Not Heat
Memory foam must dry fully before you make the bed, otherwise trapped dampness can lead to mildew and lingering odor. Open windows, run a fan, or point a cool air circulator at the mattress and allow several hours, ideally 6 to 8, until it feels completely dry to the touch.
Never use a steam cleaner, hair dryer on high heat, or prolonged direct sunlight, as high heat can warp foam and break down its support. If the room is humid, run a dehumidifier to speed evaporation without adding heat that could damage the material.
5. Protect It So You Clean Less Often
Once dry, rotate the mattress if your manufacturer recommends it, then cover it with a breathable, waterproof protector. This barrier stops spills, sweat, and allergens from reaching the foam in the first place and makes future cleaning much faster.
Wash your protector and sheets weekly and vacuum the mattress monthly to keep dust from settling. Pairing a protector with a pillow that stays fresh longer helps keep your whole sleep setup cleaner with less effort.

It is ideal for families with young children, pet owners, and anyone dealing with sweat, spills or lingering odors who prefers a plant derived, non-toxic solution.

These foaming and enzyme cleaners are designed to lift stains and odors without soaking the foam. They create a light, no rinse foam that you blot away, which helps you control moisture while targeting sweat, urine, and everyday yellowing on mattresses and upholstery.
When This Won’t Fix It
If your memory foam has a deep mold colony, a large saturated urine stain that has soaked through several inches, or foam that is crumbling, sagging, or smells musty even after thorough drying, surface cleaning will not restore it. In those cases contact a professional mattress cleaning service for deep extraction or consider replacement, especially if the mattress is older than 7 to 8 years.
Frequently Asked Questions
Can you use baking soda and vinegar on a memory foam mattress?
Yes, but use them separately and sparingly. Baking soda is safe for deodorizing when vacuumed away fully, while vinegar should be diluted heavily and only blotted on small spots, never poured. In 2026 most care experts recommend enzyme cleaners over vinegar for organic stains because they neutralize odor without leaving excess moisture.
How often should you clean a memory foam mattress?
Vacuum monthly and deodorize with baking soda every 3 to 6 months, with immediate spot cleaning for any spills. If you sweat heavily or have pets, increase vacuuming to every two weeks and use a waterproof protector. For ideas on materials that resist odors naturally, see our guide to bamboo mattress options that stay cooler and fresher.
Why does my memory foam mattress still smell after cleaning?
Lingering odor usually means moisture is still trapped inside or the baking soda was not left long enough. Let the mattress air out uncovered for a full day with good ventilation and repeat the baking soda treatment. If the smell persists after two full dry cycles, the odor may be deep inside the foam layers and need professional treatment.
