Corrosion on heavy gauge wire
Jwillis:
If you have a fairly strong acid like hydrocloric or even lemon juice .Just dip the ends into the acid until the tarnish is a gone then rinse with water and dry well .Solder as usual . If your wire is tarnished badly for the length of wire,that indicates poor sealing against moisture. Capillary action draws moisture along the full length . This can lead to corrosion severing the wire later on if theirs still moisture inside the shielding. And with an electrical charge running through the wire it's much worse .In the long term it would be advisable to just replace the wire and seal the ends with shrink wrap or rubber electrical paste.
In the case of wire connections that are exposed to long term constant exposure to moisture I prefer to solder the connections.Although there will be objections with arguments of wicking that can weaken connections there are benefits to it because it blocks moisture from entering the wire at the connection end.You don't need a lot of solder just enough to seal and weld non-welded crimp connections. If done correctly wicking won't happen and the connection will be better and last longer.
