here's what is recommended by Davis RF
FW Oxidation Cleanup:
The great advantage of the 168 strands (# 14, more if the #12) is
that it facilitates flexing and non-kinks. Fortunately it does not
break except when something comes down on it or if is rubbing against
most materials. Breaking and rejoining usually precipitates the
cleaning question.
So, here's what you do. Go to a plumbing supply and ask for
"Plumbers Acid" or get a pint of HCl but be sure you have gloves
that are rated for HCl and also wear safety glasses
Soak the end of the wire you want to clean in the acid for about 10
minutes and then use a small wire brush (Home Depot, etc) to brush
the area you want clean. Go in one direction: toward the end of the
wire, with the brush. The oxidation on the fine wires will come
off. Dip it back in the acid a few times after brushing it, then
wipe it by pulling it through a soft towel / rag.
That will do it. If you have to solder a connection to the wire,
put some silicone silastic over the whole solder joint and an inch or
so on the wire to either side. This will allow you to get at that
solder joint, if ever need be, without oxidation build up.
