You're probably right about colored vinegar likely not causing any stains but why take that chance? Especially when distilled white vinegar is by far the cheapest.
Interestingly enough vinegar is no more corrosive than water in most situations.
Every "horror story" I've seen about vinegar was either due to leaving it in a loop for prolonged periods of time, or people having mixed metals in their loop, more specifically nickle plating.
So in theory it should be safe to use. It's also possible to dip your hand in water, then tip it in molten lead, and the water will vaporize and expand creating a insulating ever expanding layer of steam on your hand keeping your hand safe from any burns for a time.
The moral of the story? Just because the science is there doesn't mean you shouldn't exercise caution.
Edit: HA, I'VE SPENT HOURS LOOKING FOR THAT DAMN CHART, AND I FINALLY FOUND THE LITTLE BASTARD!!!
(Note: Not all hours were from today!)
There ya go!
