ATF works as good as anything to remove corrosion, tried it on an outboard that had the throttle cables and about any moving part salt seized. After trying Kroil and other wonder products ATF worked the best. Outboard mechanic recommended that.
When I lived on Kodiak my blued rifles kept rusting, kept oiling them, what worked was cleaning them with very hot water first to remove the salt then oil or wax.
ATF & Acetone works splendid too. 1st time on a rusted vice that hadn't been used for 30years and now it's my go to juice. 2/3 ATF,,,
