I engrave office nameplates for my company, and I use black on white Rowmark LaserMax for them. I have found that after engraving, a fine dust surrounds the engraved areas. If I wipe off the nameplate to get rid of the dust, a lot of it gets onto the white, engraved areas. Is there a good way to clean this dust off the surface without getting it in the engraved areas? If not, is there a good way to clean the dust off the engraved areas after wiping it down? I find that once it gets on the engraved areas, it's really hard to get off of there.
