To clean your tablet, we suggest using Windex or a Display type cleaner, and lightly spray a Micro-Fiber cloth. Then gently wipe the tablet surface, cable, and pens. 

Please keep in mind that the tablet, pen, and accessories are delicate electronic devices, and too much moisture will be harmful to them. 

If you want to disinfect your tablet from viruses, please use the below link to read what the EPA recommends for that. Again, keeping in mind that Xencelabs devices are delicate electronic devices and too much moisture will be harmful.
