As pjvrefugee said. I'll add to that and recommend not using any wet lubes/grease on moving parts. My favorite is Hornady One-Shot lube for all my guns. It dries quickly, prevents corrosion, and provides a slick surface between moving parts without attracting carbon, dirt, etc. Down side is the price. It ain't cheap. http://www.hornady.com/store/One-Shot-Gun-Cleaner/
