Home Water Cut-off Valve Lubrication and Maintenance
My house has those gate valves, and I've been trying to figure out if there is anything I have to do to maintain these valves and / or lubricate the gate valve stems.
Question: How do I lubricate or otherwise maintain these kinds of valves? Should I grease them or spray the stem with silicone or something? WD-40?

Note: I hate gate valves, and I'm planning to get some of them replaced with more robust ball valves.
