How to Clean Memory Foam Mattress?
The best way to clean a memory foam mattress is to spot clean it is using mild detergent and water, use baking soda to sprinkle on the surface to remove odors, and then let it air dry completely before use. If you own a different type of mattress, refer to our standard mattress cleaning guide for proper care instructions.
Step by Step Guide to Clean Your Memory Foam Mattress
Remove Bedding and Vacuum
Take off all sheets, mattress covers, and pillows. Use a vacuum cleaner with a soft brush attachment to gently vacuum the entire surface of the mattress to remove dust, dirt, and debris.
Spot Clean Stains
Mix a small amount of mild detergent (about 1 teaspoon) with cold water. Dampen a clean cloth with the solution and gently blot the stained area. Avoid soaking the mattress because excess moisture can damage the foam.
Apply Baking Soda for Odor Removal
Sprinkle a light layer of baking soda evenly over the mattress surface. Baking soda helps absorb moisture and neutralize unpleasant odors. Let it sit for at least 30 minutes, or up to a few hours for stronger smells.
Vacuum the Baking Soda
After the baking soda has set, vacuum it off thoroughly to remove all residues.
Air Dry the Mattress
Allow your mattress to air dry completely in a well-ventilated room. Avoid direct sunlight or heat sources that could damage the foam. It may take several hours to a full day for the mattress to dry fully.
Use a Mattress Protector
To keep your memory foam mattress clean longer, use a breathable, waterproof mattress protector that can be removed and washed regularly.
Is it Safe to Wash a Memory Foam Mattress?
No, washing a memory foam mattress with water or in a washing machine is not safe because memory foam is highly absorbent and retains moisture. When soaked, the foam can become waterlogged, which damages its structure and slows down drying.
Prolonged moisture inside the foam creates an environment where mold and mildew can grow, leading to unpleasant odors and potential health risks. Additionally, washing machines can physically damage the delicate foam cells by compressing or tearing them. For these reasons, spot cleaning and careful airing are recommended instead of full washing.
Is Memory Foam Ruined if it Gets Wet?
Yes, memory foam can be ruined if it gets wet because it is a porous material that absorbs and holds moisture. When wet, the foam's structure weakens as water disrupts the open-cell design that provides its cushioning and support. This can cause the foam to lose its shape, become less resilient, and degrade faster.
Moreover, trapped moisture creates a breeding ground for mold and mildew, which damages the foam further and poses health risks. Since memory foam dries very slowly, prolonged dampness often leads to permanent damage, so it’s important to avoid saturating it.
How to Clean a Memory Foam Topper?
The best way to clean a memory foam topper is to spot clean it with mild detergent and water, use baking soda to remove odors, and let it air dry completely before using it again.
Here’s a step-by-step guide to cleaning your memory foam topper effectively:
Remove bedding and vacuum
Take off all sheets and covers. Use a vacuum cleaner with a soft brush attachment to gently vacuum the topper’s surface to remove dust, dirt, and debris.
Spot clean stains
Mix a small amount of mild detergent (about 1 teaspoon) with cold water. Dampen a clean cloth with this solution and gently blot the stained areas. Avoid soaking the foam, as excess moisture can damage it.
Apply baking soda for odor removal
Sprinkle a thin, even layer of baking soda over the entire topper surface. Baking soda helps absorb moisture and neutralize odors. Let it sit for at least 30 minutes, or up to a few hours if odors are strong.
Vacuum off the baking soda
Use the vacuum cleaner again to thoroughly remove the baking soda from the topper.
Air dry completely
Place the topper in a well-ventilated area and allow it to air dry fully. Avoid direct sunlight and heat sources that can damage the foam. Drying may take several hours or up to a full day.
Use a mattress protector or topper cover
To keep your topper clean longer, use a washable protector or cover that can be removed and laundered regularly.
By following these steps, you can keep your memory foam topper clean, fresh, and in good condition without causing damage.
How to Keep Your Memory Foam Mattress Clean?
To keep your memory foam mattress clean, use a waterproof protector, vacuum monthly, spot-clean spills immediately, and rotate it every 3–6 months.
Step-by-Step Guide:
Use a Waterproof Mattress Protector:
Cover the mattress with a breathable, waterproof protector to block sweat, spills, and allergens. Choose one with a moisture vapor transmission rate (MVTR) above 500 g/m²/day to prevent heat buildup.
Vacuum Regularly:
Use an upholstery attachment to vacuum the mattress surface every 1–2 months. Focus on seams where dust mites and debris accumulate.
Address Spills Immediately:
Blot liquids with a clean, absorbent cloth. For stains, mix 1 tsp mild dish soap with 2 cups cool water, dab (don’t scrub) the area, then blot dry. Avoid soaking the foam.
Deodorize with Baking Soda:
Sprinkle baking soda lightly over the mattress every 3–6 months. Let it sit for 4–8 hours to neutralize odors, then vacuum thoroughly.
Rotate the Mattress:
Flip or rotate it head-to-foot every 3–6 months to distribute wear evenly and prevent sagging. Check the manufacturer’s guidelines first, as some models are one-sided.
Why It Works:
Memory foam’s porous structure traps moisture and particles, making preventive care critical. A protector creates a barrier, while gentle cleaning avoids damaging the foam’s cell structure. Regular rotation combats body impressions, extending lifespan.
