I have heard that pouring coke on a corroded battery terminal is the best way to clean off the corrosion. Is this so?
NO! It does work to some extent, but coke contains enough acid, carbolic, phosphoric and citrus acid to make the metal bright and shiny, but it also leaves an acidic condition behind..Coke has a Ph of around 2.8, which will soon corrode the metal again, just as the battery acid did in the first place. Baking soda works better because it also neutralizes the battery acid and does not leave behind a corrosive acid film which is going to start attacking the wire.
