2011 F-150. Has corrosion on positive battery post (top mounted posts). Changed battery when old one died, replaced clamp and sprayed with red battery clamp spray and then this new battery clamp and battery started the blue corrosion again. I don't like corroded terminals and it seems some cars never have it and others never can get rid of it.
What causes some to corrode and some not to?

system could be overcharging causing the batteries to vent.

Check your alternator output. Voltage regulator may be defective leading to an overcharge condition.
