I have a couple of pure bristle painters brushes on my workbench, they are about half an inch wide, and if I need to clean away any dust from a piercing job's surface, I use one of these, I also saw at right angles to my eyeline most of the time and the piercing dust mostly goes down into my bench skin. Some of my piercing jobs have required me to be piercing for many hours, sometimes all day for many days.
