Auto parts stores sell a spray to keep em clean. Everytime I take a connection apart I spray them.
Forgot the "doughnuts" earlier. They and the grease are my usual practice. The Super A yesterday had none, and I just reworked the connections last spring. Gremlins or TML I guess :?: :roll:BigDaveinKY said:Those little felt "do-nuts" that are meant to absorb what acid finds it's way out,
and a coating of grease seem to keep my terminals in good shape throughout the year.
At least a year or three before I need to clean them again.
