Good job. You'll have to try different solvents, it could be just about anything. Is it hard, or soft? If it's soft, just wipe it out with a rag. If not, start with household clearners, like isopropyl alcohol and Simple Green. If that doesn't do anything and it's not melting, try Lighter Fluid or Kerosene. Try not to get it on the edge of the glass, it could start to dissolve the balsam cement between the elements.
Lube with some high temperature silicone grease, very little needed.
