In this comprehensive guide, we’ll walk you through the best ways to clean your mattress topper, what to avoid, and tips to keep it in great shape for years to come.

How to Clean a Memory Foam Mattress Topper
Step-by-Step Cleaning

-
Spot clean stains:
- Mix mild detergent with lukewarm water.
- Dip a soft cloth into the solution.
- Gently blot the stained area.
- Do not soak or rub harshly.
- Air dry completely: Place the topper in a well-ventilated area. Never expose to direct sunlight or high heat.
Important Tips
- Never wring out or twist memory foam.

Can You Machine Wash a Mattress Topper?
For most foam-based toppers, including our best mattress topper, the answer is no. Washing machines can damage the structure of memory foam and cause irreversible deformation.
Only lightweight fiber or feather toppers are generally safe to machine wash—and even then, use a commercial-size washer and delicate settings.
