Battery keeps corroding

[Eclipse 1998]

So last week I completely cleaned the pos bat terminal and here were are again caked corrosion all over it, any idea why?

electrolosis and oxidation.

quick fix: spray some anti corrosion (its essentially clear-ish spray paint) stuff on it. there are various types that are sprays, gels etc.

better fix: quality cables, battery terminals and proper grounding cables and paths and a sealed agm/gel cell battery.

Or just put some oil on it after you clean it all off! Works amazing can use spray lubes to, my favorite is chain lube.

What these guys said. Also those little anti-corosion terminal pads they sell at Advance work pretty well.
