A faucet handle that becomes stiff and hard to turn off is typically caused by heavy mineral scale (calcium and lime) accumulation inside the cartridge, dried-out internal lubrication, or an overtightened packing nut. Hard water minerals precipitate out of the water supply and form an abrasive crust that binds the moving internal parts together. Callout type="warning" title="Hygiene Warning": Shut off the water supply valves under the sink before disassembling the handle. Verification: Disassemble the cartridge, clean away mineral crust in white vinegar, apply silicone grease, and reassemble.
