Ordinary cooking spray does a lot more than keep food from sticking. I spray some on a rag and wipe down my band saw blade between uses. The spray makes the blade cut more easily and protects it from rust. It even helps keep wood pitch from sticking and gumming it up. Be sure to keep peace with your spouse and return the can to the kitchen when you’re finished with it — or better yet, buy a can for the shop.
