Has anyone here used MEK to remove toner? It's used to clean tools
used with epoxy resins (before the resin hardens), so would it harm
glass epoxy PCB material which is (obviously) already cured?
Anyway, MEK sounds like some really nasty stuff in this post:
http://groups.yahoo.com/group/Homebrew_PCBs/message/6180Does anyone here just scrub off the toner after etching using Ajax or
Comet powder, a green 3M Scotchbrite pad and water? I've used that
method to clean firmly bonded toner off of test boards used in my
toner transfer experiments and it manages to get the toner off pretty
quickly.
