All Wacom products can be safely cleaned with 70 or 75 percent isopropyl alcohol (rubbing alcohol) when applied to a soft lint free cloth. Lightly wipe the moistened cloth on the hard, nonporous surfaces of your Wacom product, such as the display, or other exterior surfaces. Don't use bleach. Avoid getting moisture in any opening, and don't submerge your Wacom product in any cleaning agents. See below for additional tips or please contact your regional Wacom customer service team.
