How to Clean Memory Foam: From Mattresses to Pillows

Just like your clothing, nearly all memory foam items feature a care instruction tag. Take a moment to familiarize yourself with it so you know which cleaning methods are recommended. You should never pop memory foam items in the washing machine or soak them through with water. That’s because memory foam is highly absorbent and quite delicate. The more moisture we add to the foam, the more difficult it will be to dry—potentially leading to mold growth and the degradation of the material's structure.

Just like rugs and upholstered furniture, memory foam accumulates dust and dust mites over time, along with pet hair and other debris. Every one to two weeks, vacuum your memory foam items with a flat-head attachment; be sure to get into any crevices. 

If you need help remembering to regularly clean your mattress, get into the habit of vacuuming it every time you change the sheets.

Some memory foam items such as pet beds and mattress toppers come with removable covers that can go in the washer and dryer (low heat is usually recommended to avoid shrinking). You should launder these every one to two weeks. The easiest thing to do is to toss them in the wash before you vacuum the memory foam.

Because memory foam is super-absorbent, you’ll want to tackle stains as soon as possible while going easy on the harsh chemicals. We recommend a gentle solution of either:

• One part gentle, clear laundry detergent and three parts water

• One part baking soda and three parts water

• Three drops of clear dishwashing solution and a cup of water

• One part white vinegar and 10 parts water

Place any of these solutions in a spray bottle, apply to the stain, and dab—do not scrub—to soak up the stain with a microfiber cloth or paper towel. Move the towel in small, circular motions toward the center of the stain so that it doesn't spread further. Be sure to let the area fully air dry before putting a removable cover back on or, if it’s a mattress, covering it with sheets.

To keep your memory foam looking and smelling fresh, give it a disinfecting clean twice a year. Most memory foam should not be steam cleaned, however. Instead, use a store-bought disinfectant specifically designed for memory foam, or lightly sprinkle the item with a layer of baking soda, then spray with a vinegar-and-water solution. Allow the item to air dry fully, then vacuum thoroughly to remove any baking soda residue. If it’s feasible, bring smaller memory foam items like pillows, pet beds, and mattress toppers outdoors to dry in the sun. 

There are situations in which you may need to disinfect more frequently. For example, if your toddler or your pup recently had an accident and you're learning to clean pee out of a mattress, you'll need to go the disinfection route. And because you’re especially up-close-and-personal with a memory foam pillow, we recommend disinfecting it on a monthly basis.
