Coke will help free a stuck seatpost in a bicycle if the frame is steel and the seat post is aluminium.

Just turn the bike upside down, pour some coke down the seat tube, leave to stand overnight, and hit the seat with a mallet the next day.

"To illustrate that, the email points out that Coke can be used to clean a toilet, help remove a rusty bolt, or remove blood from a highway accident." Yeah well why would anybody believe that if a soda can be used in such ways that it is also bad for you? I mean I flush the toilet with water! With WATER! And it removes most traces of excrement... Arg, it must be bad for you!

Coke is used to clean a toilet and not flush it. To clean a toilet, generally some acid or detergent is needed. Effectiveness of Coke being used for this purpose shows its acidic nature and its ability to dissolve the material on which it is applied.

Hitting stuck things with a mallet is probably a pretty effective way to get them unstuck, independent of the presence of coke.

Conclusion "As I suspected, no nail of any kind was dissolved by any of the sodas."

Relevant?

"Predicting if a Metal Will Dissolve in Acid" [0]

as well as

"Is Soda Acidic? – How Cola Impacts Digestion" [1] and "Why is phosphoric acid used in some Coca‑Cola drinks?" [2]

    > ranging from 2.3 to 3.5 but a pH of 2.5 is commonly cited...
the acid usually is phosphoric acid and occasionally citric acid it seems.

Still does not mean it is bad for you. Same holds for vinegar (it's acidic). Vinegar is not bad for you, at least when pored over your salad. In fact, only the dose determines the toxicity, it makes no sense to talk about toxicity with out discussing dose (or LD50 value or something.)

yeah, please drink half a litre, or even better 2 litre of vinegar and report back to us how that went.

or to reverse it - do you know anybody drinking coke in same amounts as usage of vinegar when pouring over salad?
