i recently read in the Family Handyman. The best method is to keep the area clean and free of debris. Another lubricant mentioned is by the Schwinn Company. Its a dry lubricant that does not attract dust or grime. Its used on Schwinn Mountain bikes to lube the chain, but not to collect debris.
Handyman suggested using this on sliding doors and on cabinet drawers. It comes in spray form and found only in bike shops.
