I have been preaching the dangers of Simple Green for a long time. It ruined a vinyl seat in one of my old boats when accidently spilled, and ruined the paint on the headlight bucket of my TBS. I never realized it could damage 'aluminium' though. Guess I'll only be using it for the grease spots in the driveway.
