Green oxidation and corrosion on electronic contacts can wreak havoc on the function of any electrical system. Oxidation is generally much harder to remove than other forms of corrosion, and you may have difficulty with it even if you use commercial chemicals. Fortunately, there is a common household cleaning and cooking item that will remove green corrosion from electronic contacts without damaging the contacts or costing you money.
Clean off the area as much as possible. Do not scrub, since this can damage the connections, but wipe the area down thoroughly using distilled water and a cleaning rag. This will remove dirt and grime, making the corrosion easier to spot.
Saturate a clean rag with the vinegar. Make sure that it is completely full of vinegar, but wring it out until it is not dripping.
Soak the corroded areas with the vinegar. You can lay the rag over them or use it to wipe them down, only allowing the vinegar to sit on stubborn spots. Continue wiping and soaking until the green corrosion is gone.
Wipe down the entire area with distilled water again. You should not leave vinegar on the electronic contacts permanently because it can damage wires and connections. Make sure all residue is gone before you continue.
Always turn off or unplug any electronic item before you attempt to clean green corrosion from electronic contacts.
