Cosmoline remover. I believe it is cosmoline that is still used for corrosion protection. Don't know where to buy it though. We used to get imported cars and that stuff was all over the engine compartment. We found that spray-can carpet shampoo melted it right off. No idea why it worked but it did. Lacquer thinner would work fine also since there is no paint to damage.
