For one-handle faucets with a 1225 cartridge, simply remove the cartridge and lubricate it both inside and out with silicone-based grease (Moen part number 99915). Do not use plumber's grade faucet grease, silicon sprays or any lubricant that contain petroleum. Petroleum based lubricants may react with rubber seals and actually cause the faucet to become even more difficult to operate.

For two-handle faucets, we recommend replacing the cartridge. The part number for a two-handle kitchen cartridge is 1224. You can purchase these parts online by visiting our Replacement Part Store.

For one-handle faucets with a 1255 or 4000 cartridge, replace the cartridge.
