What is the best lubricant to use on machinery and vises so that they work freely and sawdust does not clog up the mechanisms?—Myrl Phelps

Bob Oswald replies: I use Bostik Lubricants. Aerosol can application is easy and the lubricant drys, leaving a lubricating film that won’t attract dust. Available from Woodcraft, Rockler, etc.

Peter James replies: I like a bicycle chain lube called White Lightning. It lubricates without attracting the dirt and dust. You can get it at most bike shops.

Bruce Wedlock replies: Try WD-40 Specialist Dirt & Dust Resistant Dry Lube Spray. It works great on tablesaw gears, etc. Available from amazon.com.
