A lot of folks aren't aware that Simple Green is a "concentrate"!!!
So I've seen it used full strength in applications that it shouldn't be, like wheels! In fact, other than cleaning graffiti off walls, it shouldn't be more than 50-50 water to Simple Green, and that is for things like engine grime.
Show car owners swear by this stuff, and they would be most concerned about ruining components than anyone I know.
