What are y'all using to lube valves?

Mine get very hard to move but, it is only the shaft that seems to get sticky. I spray the shaft; when I have the valve open; with some door lock lubricate that I keep in the camper (the door lock seems to get sticky a lot too) that seems to keep it working easily for a few months again.
