RE: [DML] Coca-Cola - Was rusted screws ??

["Gus Schlachter" <gus@xxxx>]

I have doubts about the rust-destroying properties of Coca-Cola. It has
small amounts phosphoric acid, as some other soft drinks do. I believe the
acidic action is the result of the carbonation, if I remember my high school
chemistry correctly. You're better off removing rust with a chemical
designed for the purpose, like "B'LASTER Penatrating Catalyst", manufactured
in Cleveland, OH (and my only door price from Car Show 2000).

When I worked in a restaurant, our soda dispensers had valves that would
click over from an empty syrup container to the next one. But the supplier
refused to hook up the Diet Pepsi to the valves. Why? Because it would eat
the o-rings in about a month. Sodas are acidic, some more than others.
They may have limited automotive application but I would use them strictly
for refreshment, and Coca-Cola has over a 90% refreshment rate. :-)
