: Be very careful with any solvents that you use. Any oil based products will
: interfere with the epoxy to substrate bond. Some manufacturers recommend
: against the use of acetone as a wash stating that most acetone is
: reclaimed and may contain impurities that will hinder good bonding.

: If you do consider using solvents, be sure to do a test on scrap first. Ricci

TAP Plastic sell a non-recycled acetone. I assume that non-recycled acetone means no contaminant. Scientisfic supply stores also sell reagent grade that is pure but at much higher price.
