I have had great luck by heating Vaseline to the hot liquid state then brush it on all the exposed lead and I dip the cable ends also. Doing this I have had 1 terminal that got corroded out of several hundreds.
That gets you a thin coat and lasts for years. "Clean and tight" is nice but it gets corroded at some point, and I hate cleaning 1 terminal or 20!

We see corrosion all the time. When we replace batteries, we use zinc coated copper terminals and apply a thin layer of grease with a toothbrush to every exposed portion of the connectors. This simple step, with the occasional reapplication, keeps all terminals as fresh as the day installed for many years. I am speaking from experience of hundreds of installations.
