I noticed the technician who performed the battery replacement in our UPS (which has 40 "jars" as he calls them) used a Scotch-Brite Multi-Purpose Scour Pad to clean all the battery terminals and the cable terminal connectors. It works very well. The pad is made of non-conductive material, so it does not leave any conductive residue behind, as might occur if steel wool were used. It has just enough abrasion it will clean up the surfaces without putting scratches in them.

We employ these things for a number of uses, one being to shine copper pipe before we solder it. Also just used some to clean up the bottom paint on the boat. Was able to do it wet and dust free.

One of the most frequently used tools in my electrical kit is a corrosion removal "pen". This device actually uses many thin strands of fiberglass to scuff away corrosion on electrical contacts and the like. As the strands wear away, they can be advanced like you would the lead on a mechanical pencil. It employs the same principle as the Scotch-Brite pad, but can be used to clean up small contacts, electrical connectors and plugs.

The price has gone up since I last purchased one of these, but it really is a fantastic tool. I keep one in the shop, and the other on the boat. They are particularly good for cleaning up fuse holders under the console, which always seem to get a bit of corrosion on them over the winter.
