Specialist Lithium Grease Spray by WD-40
Grease is a superior lubricant for many applications. It remains in the place where it is needed, unlike oil, which can run away from its intended placement. Grease also tends to last longer and requires fewer applications, especially when exposed to the elements. However, grease is messy. Traditionally it comes in tubs and tubes and must be applied using your hands or specialty grease guns. I have avoided using it the past because of the mess involved.
A few years ago I found lithium grease in a spray can. It has all of the benefits of grease and none of the mess. I use it on everything from bicycle chains to door hinges. You can use the regular spray tip for wide coverage or attach the straw for precision application.
