[Sca-cooks] Rust removal

[grizly]

STUPENDOUS!  I did a google search for rust removal and Mr. Wizard . . . .
found this website from a guy who does the same thing with old tools.

The negative (black) goes to the "keeper" piece and the positive (red) goes
to the sacrificial scrap piece.  He added some baking sode as a catalyst to
speed up his electrolysis.  The following link has better description; boh
have pictures.  This one uses "washing soda" which you can find in most
markets.  Arm and Hammer is usually unscented and plain.

Use salt water, washing soda (sodium carbonate . . . NOT baking soda) and a
piece of wrinkled aluminum foil to clean silver pieces.  Immerse all and put
silver in touch with the foil . . . no electrodes needed.  Silver Plate
isn't so helpful, but sterling cleans with zero effort.

Don't waste your time with a wire brush- they're pretty dangerous anyway,
when one of the wires comes loose, if you aren't wearing a leather apron. A
guy just managed to impale his left testicle through his jeans a few days
ago. And, never mind, using a wire brush tends to drive the rust deeper, so
your food will taste like rust for a while.

Instead, get a battery charger. You should have one, if not you need one ;-)
Put one contact on the metal you're cleaning, attach the other to a piece of
scrap metal- iron or steel- and immerse the pieces in salt water in a
plastic
container, seperated a bit. Turn the charger on to "trickle" and go away for
a while. If when you come back, the piece of metal has rust attached to it,
you're doing it the right way- if not, you need to switch the clamps, so the
polarity goes the other way (I can never remember which way it goes, and for
Heaven's Sakes, turn the thing OFF when you switch the clamps).

It's completely the easiest way to remove rust I know of, and doesn't risk
driving nasty stuff into your cast iron, and, depending on how much rust you
have, shouldn't take more than a few hours to accomplish.
