Troy,

You are seeing the results of what acid does to nearly any metal, that's why they sell it in plastic jugs


It's also why I caution users against using the home brew on delicate or plated items as it will remove the rust first, but the good metal is next, it's just slower acting on good metal. The products I've mentioned before such as Evaporust will give the same rust removing results (yes it costs more than vinigar & lemon juice) without doing ANY harm to the good metal below it, so choose your rust removal products wisely.

*Ever cover your leftover spaghetti with aluminum foil? If the foil is toucing the foil you'l find holes in it the next day!
