your first step should be looking up the manufacturer

and finding out what they recommend as a cleaning method.

While mousepads made of a harder material,

like plastic or rubber,

can typically be washed using a damp cloth,

mousepads made of cloth

may take some additional steps to get clean.

Here is a method that could work well with your mousepad.

Fill your sink with warm water

and submerge your mousepad.

Using a soft brush or sponge,

apply a small dab of mild dish soap

and then gently scrub the pad.

Then, rinse thoroughly.

Use a clean towel to help dry the pad,

then leave it out to dry for several hours.

Once it's completely dry,

enjoy your new, clean mousepad.
