[ARC5] Silver refurbishment

[Richard Knoppow]

    The problem is that its not silver oxide, its silver sulfide, 
which is a very poor conductor. There are various substances 
which will either remove it but you will be removing some metal 
too. Any silver polish will do the trick but its best to start 
with something mild.
