To clean terminals and cable lugs it is often written (or said) that baking soda solution is the way to go. What is the optimum solution? How much baking soda per unit volume?
Kopr-Kote by Jetlube does the same thing and doubles as a terrific anti-seize compound.Somebody (maybe here) turned me on to "NCP2":
I've only used it since last year, so I can't yet say how effective it is, but so far so good. You brush it on, and it leaves a thick, somewhat sticky layer of material on the terminals.
A usual cause is out gassing during charging. The battery vents gasses and aerosols contain sulfuric acid. Older batteries and over charging cause more gassing.
