I suggest you go to the auto parts store and get a battery terminal cleaner.
They are easier to use than a wire brush. As for the anti-oxidant stuff
they sell for inflated prices I have found that Vaseline works better.


Ummmm.... Vaseline is an electrical insulator. If you apply it between the
terminal and the post -- which is where you *really* need corrosion prevention
-- it ain't gonna work. OxGard, on the other hand, is conductive, and can be
applied where it's needed the most.


How come there is so much corrosion between the
terminal and the post? In most cases they are the
same material (lead), so the corrosion isn't
caused by dissimilar materials.

I like what another person wrote--new batteries
don't have much corrosion. So what does that tell
you? Maybe cleanliness is a deterrent and that
corrosive gas or corrosive liquids are a problem?

In my experience, covering the whole connection
with some type of material is what prevents
corrosion on older batteries. As for vaseline--it
works. And if you put a light coat on the
connections surfaces, it still works because it is
thin and squeezes out so you get a good electrical
connection. But, I prefer to have the connection
clean, make the connection and tighten, then rub
in whatever you want, and vaseline is just fine,
but I think a heavy grease works better. Lasts
for several years. Best bet is a good battery and
charger so you don't get any spewing of corrosive
materials.
