Glad to see this thread still around, and even more pertinent info added. Heres a tip I found online while searching ground straps. You can revive wires to practically brand new. Even the most corroded and dirtiest of wires. You need: 2 containers(cups,bowls,jars,tupperware,etc.) In one container add 1 tablespoon of table salt and add vinegar to a level just below full(white,cider,balsamic, etc. Don't matter.) You're making an acidic solution to dissolve the surface contaminants on the copper strands of the wire. I the other container add 1 tablespoon of baking soda and fill to a level just below full with plain water. This will neutralize the acid solutions effect on the wires. Add as much salt to the vinegar that will dissolve, and add more baking soda to the plain water to make it cloudy. Now just swirl your wire in the salt/vinegar solution for a minute or two and you will see it return to it's original form, remove the wire and immediately dunk it into the baking soda/water solution for 10-20 seconds. BAM! clean wires ready to solder some ring terminals onto to make ground straps.
