Default Dirty trick #22-137 Corroded wires

When you encounter lovely black copper wire, and you will if you're in a salt area, vinegar will remove the corrosion in short time and return the copper to bright connectable status.

The easiest and best way I've found to treat such wires is to employ the wonderful plastic stem vases florists use on rose stems. The cap pops off easily, dump the water and replace with vinegar. Put cap back on and insert wire to self clean.

Generally the minivases are easier to obtain from Funeral Homes than florists. They are reusable until stepped on.

Be ery wary of vinegar as a rust removal agent. You can pull out an object that looks clean but has only carbon structure with no iron molecules left.

Rust conversion is a Phosphoric acid process 5 to 8% in water solution. Phosphoric is the only acid that doesn't attack good iron. Lot of Phosphoric converter is sold by Locktite & others. Add a little dissolved magnesium if you want a nice black color. Go up to 50% Phosphoric and Phosphoric becomes a rust remover.

Do NOT get Phosphoric around aluminum unless you want the aluminum to disappear.

Want to chelate rust, get a bag of cow molasses.

Electroplating rust off is the fastest process that works.

Blasting with any media, other than soda or corncob just peens rust seeds in for future growth followed by coating spall.

A few times. I'm ancient enough to remember old timers polishing golf clubs and bumpers with Coke and crumpled aluminum foil.

There are far more efficient ways than Coke and more cost effective as well.
