Hey David…….. I told Sal that I had a special cleaner for electrical parts that I got from when I worked at the airport, but I could not find it. I was pissed because I could not find that product anywhere, and my label had come off of it, but I knew what the can was. Believe it or not I used a Carburator Cleaner from your local parts store…. I just sprayed just a dab of it and let it sit for just a minute then I used an old toothbrush and brushed over the corrosion. That cleaner left a little film behind so after I cleaned it with the brush I used an old piece or T-Shirt to clean off the rest. Never went out and bought anything for this , all household items laying around the house and alittle bit of thinking.
Good luck if you are thinking of using this technique…….. Dont be trigger happy with the Can… just one spray should do it.

Rob.
