Don't use it on anything shiney - it will eat away the finish. Any bare metal will permanently discolor. Since I have "all of the above" in my boat, I threw my bottle in the trash. Simple Green right now, but I keep hearing good things about the Castrol Super Clean...

Super Clean is just as big a problem they both contain too much lye, which makes them corrosive.

BTW I sell a ton of Castrol products and I won't let my employee's use it.

I pretty much stick to the Biokleen cleaners. I figure they work real well and I worked too freakin hard to get what I got. I ain't using nothing on it that wasn't designed for it. Kinda like my ex-wife :D
