RE: [TN] Rust RemovalYou can demonstrate its effectiveness easily by
brightening a copper coin, adding a little washing up liquid to improve
wetting also converts Coke to a reasonable flux as the acid de-oxidises and
the sugar (by Fehlings reaction) keeps the metal deoxidises at soldering
temps, not for electronics use obviously.
Finally on this from me you may also be able to to show your children the
bad effects of too much coke by "borrowing" one of the teeth they leave
under their pillows for the tooth fairy. After a few weeks immersion the
tooth will disappear.

  Since Dave just mentioned it....

  One thing you might actually try (depending on your article to be
de-rusted) is Coke itself....

  It being a dilute phosphoric acid solution & all.

  Just a thought

  Hi Earl! One method of "removing" rust which hasn't been mentioned is
  electrochemical reduction. It is expensive, time consuming and probably
  wouldn't make sense for your application but it is one of the more common
  methods used in marine artifact restoration. A good use example is the
  restoration of the Hunley submarine.

  Well, time for a Coke (or I could swipe one of Doug's Dews).

  Rudy, and others on and off line, I appreciate your input. I especially
  like
  Rudy's caution about what damage rust, and its removal, does to ferrous
  surfaces.

  I can't think of anything else about this subject/pot that deserves
  stirring. However, I bet someone else can.
