i agree..

Carbs are die-cast from a primarily zinc alloy (pot metal/white metal). Zinc oxide is white. Although the oxide dissolves in both acids and bases, the base metal may also dissolve depending on strength and composition of the bath.

CLR is probably the safest thing to use. It's just a dilute mix of mild acids, mostly phosphoric. If it wasn't so expensive i'd go get some just to play with it.
