[Amps] How to get the blue markings off of aluminum stock

[Al Kozakiewicz]

>>>I would try "Goof Off" http://www.goof-off.com/ Home Depot, Lowes, & many other places sell it.

Contains alcohol, anti-freeze and an acid that may etch aluminum.

A lot of the industrial ink jet printers don't use an ink at all; many are polymers.  Think toner.

Try acetone, toluene or MEK (methyl ethyl ketone).  All are solvents that will  attack various plastics but not etch aluminum.  The really nasty heavy-duty paint removers are generous with the MEK.
