I need a good way to clean the oxides off copper electric wire. I run
and splice wire outdoors and occasionally need to make new splices when
lightning, animals or weather do bad things. It would be EZ if I could
being it to my bench but it all has to be done in the middle of a field,
maybe I can get an estension cord there. Is there some simple spray or
dip that will strip the old oxides off so I can make a decent twist or
solder splice? I don't have the luxury of cutting much off since most
of the wire is underground.

Any help appreciated.

I'd try a CO2 bottle, regulator and Paasche "air eraser" or LAC#3.

The latter is a gritblaster that looks like an air brush, shoots very
fine but quite aggressive grit. It cleans copper bright about
instantly, doesn't use much air (or CO2) in the process.
