Choke Lubricant.
Got a clean, old sock? Turn it inside out, place any good quality light grease that repels moisture on it (quite a lot), turn it back to the right side and rub till the grease starts coming through the cloth. You are now ready to grease chokes. They will not stick if this is done properly. The sock works great for a quick wipe down of any gun exterior when putting away or storing. Comes clean with a wipe from a paper towel.Add grease as necessary to the sock, however, you will find that you will not need to replenish grease often. I keep both a sock and paper towels with my guns.
