Bike shops sell a liquid parafin based lube that dries so it attracts no dirt. A similar aerosol product is available at off road motorcycle shops. I have had good luck with the bike chain lube.
To remove the old great try Brake Clean in an aerosol can, found at auto supply stores. It cuts everything and is used primarily by brake shops. You can also use a product called Grease Lighting found in every hardware and supermaket. I would be very cautious with the Teflon spray. It will leave a hard to remove residue and anything it lands on. I used it on the TV and had to get a special cleaner to get it off the plastic trim.
