[sdiy] Slide pot cleaning

Does polishing cream actually improve conductivity by removing oxide build up?
It's not something I've ever used.

I would rather take time to do the job properly, but not sure what is the best way to proceed?  I have access to a dry compressed-air line, dish soap, cotton buds, Isopropyl alcohol, acetone, silicone grease, soldering/de-soldering tools, etc, but don't want to risk making the problem worse without asking for advice first.
