Learning the right ways to clean your mattress topper not only keeps it fresh for sleeping but also extends its lifespan before needing replacement.
Unlike typical bedding that can be tossed in the washing machine, mattress toppers require special care to avoid damage and odors.
This guide on cleaning and maintaining your mattress topper will ensure it stays in excellent shape for years.
Expert Techniques for Mattress Topper Care
When you invest in a mattress topper, understanding the best cleaning methods is essential. Our cleaning experts are here to assist with your cleaning queries.
Is Washing Your Mattress Topper Possible?
A common question is whether you can wash a mattress topper. The short answer is yes, but it must be done correctly to avoid ruining it.
Alicia Sokolowski, a cleaning expert, emphasizes, 'If your topper is machine washable, wash it to eliminate sweat, dust mites, and allergens, as it's designed to withstand water and detergent without losing its shape.'
Generally, only wash toppers that are labeled machine washable, like cotton, polyester, and some down or feather types. Always check the care label for cleaning instructions, and if absent, research the material online for guidelines.
Ensure your mattress topper fits in your washing machine. Larger sizes, especially king-size, may need to be spot cleaned instead of machine washed.
Memory foam and latex toppers typically aren't machine washable but can be spot cleaned with a gentle detergent.
Sylvia Emuwa, another cleaning expert, notes that foam mattresses are sensitive to machine agitation and moisture retention, which can lead to mold and mildew.
Removing Stains from a Mattress Topper

Quick stain removal is essential
Whether machine washable or not, stains may require careful treatment to avoid damaging the topper's structure.
Spot treat stains first with an appropriate cleaner, such as Resolve Multi-Fabric Cleaner, before washing.
Use a mild, eco-friendly detergent like AspenClean Natural Laundry Detergent. Avoid bleach or harsh chemicals that can weaken the fabric.
Follow these practical steps to spot clean:
1. Remove Bedding and Read Care Labels
Take off all bedding, including pillows and sheets, and check their care labels for cleaning instructions.
2. Treat Stains by Type
Quickly spot-treat spills when they occur, or address stains that have developed over time.
Drew Miller, a sleep consultant, suggests using a mix of baking soda and white vinegar for most stains, like with White Distilled Vinegar.
For wet stains, blot with a towel. For old stains, moisten slightly before applying cleaning solutions.
For specific stains, use these methods:
- Coffee stains: Treat with dish soap and vinegar. We recommend Dawn Ultra Dish Soap.
- Oil stains: Sprinkle baking soda to absorb oil, let it sit, then vacuum. Follow with a mix of dish soap and water.
- Blood stains: Use cold water and white vinegar, blotting and rinsing to remove residue.
- Urine stains: Natural enzyme cleaners like Simple Solution Extreme Pet Spray can help.
For stubborn stains, consider professional cleaning.
3. Deodorize Your Topper
Deodorizing with baking soda is a good idea. Sprinkle a layer across the topper and let it sit for at least four hours, or a full day if possible.
Add a few drops of essential oil to the baking soda for a fresh scent. When finished, remove the baking soda with a vacuum.
4. Allow for Complete Drying
Ensure your topper dries thoroughly to prevent mold and mildew. Air-dry it outside, as sunlight can help eliminate bacteria.
Cleaning Memory Foam Mattress Toppers

Memory foam toppers require gentle care
Memory foam toppers need careful cleaning to avoid damage. Follow these steps:
- Strip Bedding: Lay the topper flat for easier cleaning.
- Vacuum: Use a soft brush attachment to clean the surface and sides.
- Deodorize: Sprinkle baking soda, let it sit, then vacuum.
- Spot Clean: Apply cleaning solution sparingly, allowing it to sit before blotting.
- Air Dry: Use a dehumidifier to help dry the topper.
Use appropriate cleaning solutions based on the stain type.
Storing Your Mattress Topper

Proper storage keeps your topper in great shape
When not in use, follow these tips for proper mattress topper storage:
- Clean First: Ensure the topper is clean and dry before storage.
- Roll It Up: Rolling prevents creases; store under the bed or in a closet.
- Use a Storage Bag: If available, use the original bag to protect the topper.
- Choose a Cool, Dry Place: Store in an area with stable temperatures and low humidity.
Should You Flip Your Mattress Topper?

Rotate or clean your topper instead of flipping it
Flipping may not be suitable for all mattress toppers. Hybrid toppers often have a designated top and bottom, making flipping unnecessary.
Instead, consider these options:
- Rotate: Shift your topper to distribute wear evenly.
- Clean: Follow the cleaning instructions above.
- Choose the Right Size: Ensure your topper fits your bed properly to avoid wear.
Are Mattress Toppers Antibacterial?

Antibacterial toppers can help but aren't a substitute for cleaning
Some mattress toppers advertise antibacterial properties. However, only certain materials effectively inhibit bacteria growth.
Antimicrobial materials like bamboo or eucalyptus fibers work well, as do some polyester blends. These toppers can reduce stains and odors but still require regular cleaning.
