Replace the sockets. Auto parts stores sell them for very few dollars.
The labor in doing so will be significantly less than cleaning.
Since the sockets are already rusted, that means the minimal corrosion protection the original manufacturer applied went AWOL, and you will be constantly re-cleaning.
Swab silicone GREASE
(not RTV) over the new connectors for protection against oxidation.
