I have 1 solar light that the battery contacts have some corrosion,it does
not light up ,new batteries,take it down in the basement tried using sand

the market that can eat away the corrosion.Thanks


The real trick is to eliminate the non-conductive film and
lean the rest. Sand paper tends to take off the good with the bad. I
suspect you may have done the damage.

I suggest using something designed for the job. You can buy
contact cleaner spray and it should be accompanied by the contact
lube-protection spray. I get mine from Radio Shack (Tandy some
places).
