I run into a lot of corrosion formed by leaky zinc/carbon and alkaline batteries. The battery electrolyte is caustic and forms a hard coating on the nickel plated battery contacts.
DeoxIT D-Series doesn’t seem to have any effect on this type of corrosion. I have to mechanically remove as much of the corrosion as possible and rinse it with a mild acid (dilute water and vinegar) followed by blowing dry with compressed air. After that I use one of the DeoxIT lube products to protect from further corrosion.
