Step 4 · Remove Old Faucet and Clean Sink Surface
From above the sink, carefully lift the entire old faucet assembly—handles, spout, and sprayer—out of the sink holes. Set it aside. You will likely find a ring of old, hardened plumber's putty or a deteriorated gasket. Use a plastic putty knife to scrape away the bulk of this old sealant. Then, use an all-purpose cleaner and some rags or a non-abrasive scrub pad to thoroughly clean the sink surface where the new faucet will sit. Ensure the area is completely clean and dry.
