I use windex (mostly ammonia) for cleaning everything at first,
usually in a momentary contact sort of way, IE, not soaking for
days.  I have no, 0, incidents to report.  Been doing it for years.
Heard a rumor once that it shouldn't be gotten on car body 
paint, but that's just a rumor and OT here.
