I have even considered an acid flux bath, followed by a long water
rinse, but that's always been verboten for electrical work.

Hi Mike,

It seems you've been out of electronics production for a verrry
loooong time. Acid flux is commonly used for environmental reasons.

Try dipping it into a small portion of Coca Cola overnight. The
Phosphoric Acid in it will strip anything....

Hi Richard

I once made a small tub to hold the rusty part and filled it with a
solution of water and washing soda
(http://www.stovebolt.com/techtips/ru..._derusting.htm) . A
small DC current is then conducted from a metal part in the solution to the
rusty part. The rusty part got shiny after a few hours.

Hi Jerry,

That's a another arrow for the quiver. Thanx.

Make sure to read the PDF file too. Apparently stainless steel will
produce chromate in the solution if used as an electrode.

or other chromate - they are all mostly bad for you.

Since my coil has some stainless parts in the current path, I'll try
suspending it so that they don't touch the solution, and rotate the coil
to clean.

Dilute it and toss it on your lawn. Unless your lawn fertilizer has
chromium in its composition, you lawn is very likely to be chromium
deprived ...

Neat idea. Washing soda (sodium carbonate) is sold at paint stores as
TSP substitute.
