Greasing a faucet handle requires accessing the internal valve mechanism. Shut off the hot and cold water supply valves under the sink, use an Allen wrench to remove the handle set-screw, and pull the handle off the stem. Take out the cartridge, wipe it clean, and apply a generous coating of waterproof food-grade silicone grease around all moving stems, sliding surfaces, and rubber O-rings. Reassemble the handle securely. Callout type="warning" title="Hygiene Warning": Shut off the water supply valves under the sink before beginning repairs. Verification: Operate the handle to confirm it glides smoothly without binding or stiffness.
