bonnie john,
Last week I had want to get my fishing gear out again (used last around 8 years ago). My needle nosed pliers were last used for getting the hook out of the mouth of a rather angry flathead, and were rusted shut.
Gave it a couple drops of Specialty Formulations "Purple Problem Solver" in a few places, let it sit in the sun while we went for a couple hour walk, and got them half open. Worked them open/closed a couple of times and watched the rust bleed out of the joints.
Simple one handed operation thereafter.
Got half a bottle left...alas when that's gone, that's it.
Mola's LCD20/ATF brew has a solid reputation.
If you want to augment the acetone ATF, try "Ed's Red". Acetone ATF, gum turps and kero/mineral spirit...and lanoline if you want to improve it.
Got some lying around if you want to drop by.
