My coworker has three huge, 2ft by 4-5ft, shop rags that he uses to cover tear downs that aren't immediately going back together but for the life of me I can't find anything like it for myself. The reason I like his is no lint, heavy so they don't blow off and they hold a bit of oil/grease so there's no rust or dust. Unfortunately he received them as a hand-me-down from another mechanic so that's a dead end for me.
