The easiest and simplest way to clean the memory foam mattress is by regularly vacuuming the mattress. A handheld vacuum is a perfect option for cleaning the memory foam. If the mattress comes with a removable cover, remove it before vacuuming. Vacuum all the sides of the mattress. You can wash the removable cover by hand.
If you have stains, use mild detergents instead of harsh chemicals such as ammonia or bleach. If you do not have a mild detergent, you can use a mixture of water and vinegar and clean the stain with a sponge.
If liquid spills on the mattress, you can place it in the sunlight immediately. However, keep turning the sides of the mattress so that it dries out evenly. If there is no sunlight, place baking soda over the area with liquid to absorb the liquid. If your mattress is slightly damp, use a blow dryer to dry it but don’t let it get too hot.
