I started out with some battery cleaner to help loosen things up a little. Let it sit for a couple of minutes.




Then I took a small screw driver and scraped off the corrosive coating. See how it wants to be shiny and new again?



Some other materials I used, probably not all required, but I wanted to do it right the first time. I started with the battery cleaner. Then I scraped off as much corrosive coating as I could with the little screw driver. Then I used some fine grit paper to take off even more corrosive coating. Afterwords I sprayed it down with electrical contact cleaner and let it dry. You'll see what I used the di-electric grease for in a minute.



Now we're looking good . . .
