I think it is probably calcium like deposits around the bulb rather than rust. I have not done it but wonder if it would be worth trying some of the products used for removing lime deposits -- or maybe one of the radiator flushing products.
It should be possible to use some modeling clay to make sort of a dam or plug around the opening to keep the product surrounding the bulb while it works for a day or so. Maybe change it a couple of times too. Doubt it would hurt anything to try but no idea if it would work either.

I have had some luck cleaning things with EvapoRust. I wonder if it would be EvapoOtherCrud, too. The possibility exists.
The dam idea is good. Never discount chewing gum, either.

If you're not having fun, maybe it's your own damned fault.

CLR too maybe? Works around our place with my plumbing that carries water that seems to be 50% limestone.

What about a solution of oxalic acid or one of the radiator flush products. In some of the older threads Oxalic acid has been recommended for cleaning the cooling system. The acid does not seem to damage anything when used and acid should work on limestone deposits if they are the cause of the sticking as well as any rust. In theory it would probably work better than penetrating fluid..
