How To Clean a Memory Foam Mattress Topper

On average, you spend 7 to 8 hours in or on your bed every day. In that time, a lot of your dead skin cells, sweat, and body oil accumulates in, on, and around your foam mattress and/or mattress toppers. The skin cells and body fluids breed allergens to your bed like dust mites, bacteria, fungi, and many others. These allergens feed on your dead skin cells, thrive in the humid atmosphere of your bed, and can trigger multiple allergy symptoms such as sneezing, coughing, runny nose, and breathing difficulties. To avoid allergic reactions, you must clean your mattress toppers periodically, especially when it’s made of memory foam. Today you’ll learn how to clean a memory foam topper as well as extend its life.

What Is Memory Foam?

Originally developed by NASA as a way to improve the safety of aircraft cushions, the foam mattress, aka memory foam, was popularized because of the way it provided softness and comfort by molding to the shape of any and every individual. Those who choose not to buy a memory foam mattress oftentimes will opt for a less expensive foam topper to get the same or at least a similar feeling to sleeping on what many have called the best mattress. Those that do get a foam mattress do not need to get a topper, but some do, usually for either their pets or their children. However, buying it is one thing, maintaining is another.

A foam mattress or foam mattress topper needs to be kept clean, and for you to do so, you have to know how to properly care for them. Doing so is both beneficial for personal hygiene, but also beneficial in protecting you from allergens and many other potentially harmful microbes.

What You Should Know Before You Start Cleaning

However, a foam mattress topper cannot be washed in the same way you would wash any other type of topper. This is because throwing it in a washing machine can cause moisture retention. This will weigh the memory foam down and either damage the structure of the foam or breed bacteria that cause mold, mildew, odor, and/or further material damage. Here are some of the most widely used methods of cleaning memory foam and memory foam mattress toppers.
