Hand-washing is by far the best, and the washing instructions are the same for all gaming brands.

Mix soap and water together, then use the sponge, soak it in the mix, use a soft cloth or soft side of a sponge, rub the surface of the mouse pad lightly in a circular motion, and rinse the mouse pad with clean warm water.

Pat the mouse pad dry and then let the mouse pad air-dry (keep out of the sun) for at least 12 hours (we recommend 24 hours). Do not use a hair dryer or apply consistent direct heat to the surface. 

Do not place the mousepad in a washing machine. This will damage the pad and make it unusable.
