I saw this video on the web recently:

It got me thinking, would vinegar be a good way to remove rusted clarinet screws?
it seems like one could dab vinegar on a rusted clarinet screw periodically and remove it. If anyone else has any interesting or radical to try please post it!

Probably not but there are some other methods that will work. I'm going to assume that you probably have either a pivot screw or a rod screw that doesn't want to come out. If you can remove the post that has the screw stuck it it you can soak it in a heated mixture of water and alum. This will dissolve the steel screw but will not harms the non-ferrous metal of the post.
Be warned that this will take a LONG time. I've only had to do this once to remove a stuck pivot screw. It was on an HN White Silver King where the posts were soldered to the body and could not be removed. I had it soaking in a 5 gallon pot filled with water and alum for nearly a week before the last bits of the screw were gone. It would have gone a lot faster if I could have removed the bulk of the screw with a dental motor beforehand but the configuration of the instrument (non removable bell) didn't allow me to do this without risking further damage.

Ive done the alum before to remove a rod from a key. When I did it i used a copper pot over a hot plate. The reaction was going fine for awhile but then the water turned murky and the key gained an ugly film over it. No matter what i did the alum would no longer dissolve the steel and I ended up having to unsolder the key and solder in a new nickel tube.
I've also learned that the threads on clarinet screws are not always standardized expessically with older clarinets so finding a replacement can be hard.
I suppose ill stick to penitrating oil and heat for now.
