Pics might be helpful, but this is my general advice:
1. Strip frame
2. Clean and degrease frame/fork
3. Soak frame/fork in
oxalic acid bath (approx. 24-36 hours with a dilution of about 1 tablespoon per gallon of water)
4. Apply wax (I avoid cleaning/polishing wax unless paint has dulled)
5. Rebuild with new grease/bearings/cables as needed
