Why bother to try to clean? As mentioned, the copper has probably
dissappeared from the ground rod, under ground. A trick you might try:
Check your local garden center for Powdered Copper Sulfate (CU S O-4
)-it is used as a pest control, for gardens- also, is used as an
ingrediant in the solution for plateing copper to items! (a greenish
powder) Mix this with water, and
then pour it on to the ground rod/earth (warning- you may stearlize the
ground - don't try this around ornimental plants, nor growth that you
wish to keep alive!) May take several gallons, but with electrolyisis,
may help replate the ground rod, and will certainly improve the ground's
conductivity to the ground rod! As info, Jim NN7K

I have a ground rod that has become corroded. My VOM measures no
continuity between the rod and the ground wire.

Is there and easy spray-on cleaner of some kind that would make the
ground rod shiney and conductive again, where I attach the ground
wire? (I don't think I can pull the rod out to replace it; it'd be
easier to fix what I have.)

Tnx,
