Thanks for all the suggestions. I soaked the dimmer disc in vinegar for 8 hours and it cleaned up the brass tab pretty well - well enough that continuity has been restored. I tried soldering the joint between the brass tab and the resistor coil, but the coil material won't take the solder. I will slather the joint with no-corrode goop before I reassemble the switch.
