You will need a blaster with Sharpie on it, a paper towel, and rubbing alcohol.
Wet your paper towel with rubbing alcohol and rub the Sharpie off.
It just comes right off! It's that easy!
Note: it comes off best if the Sharpie is written on smooth, glossy plastic. But even if the Sharpie is written on rough textured plastic (for example, the bottom of a Nite Finder handle) it just takes a bit of elbow grease to get if off.
