Can you wash a mattress topper?

As toppers are typically exposed sheets of material, cleaning them using a standard washing machine setup is not advised. Toppers are much more fragile than other pieces of bedding, and using a washing machine can quickly wear them down.

How do you deep clean a mattress topper?

Mix equal parts cool water and distilled white vinegar in a spray bottle. Spray the affected areas of the mattress topper. Gently blot out excess moisture using a towel. Sprinkle a generous layer of baking soda over the mattress topper, and allow to rest for at least 8 hours.
