Installing a sink requires not only installing the hardware, but sealing around the area where the faucet meets the sink. Caulk prevents water from leaking underneath the faucet after collecting on the sink. Proper installation of caulk at the time of installation will create a seal that lasts for years. If the caulk underneath the sink begins to crack, peel or change color, however, you will need to remove the old caulk and seal the faucet again.

Apply a caulk remover to the old caulk surrounding the faucet. Caulk remover is available from most hardware and plumbing stores. Allow the caulk remover to sit for the recommended period of time.
Scrape the caulk with a putty knife to remove it from around the faucet. Be careful not to scratch the faucet.
Apply masking tape to the bottom of the faucet, so just the crack between the faucet and the sink is showing.
Open your tube of caulk and cut off the tip to open it.
Squeeze the tube until you get a bead of caulk moving from the tip. Wipe the caulk off the tip.
Apply the tip of the caulk tube to the crack between the faucet and the sink. Squeeze the tube and begin moving it along the crack. Keep the tube moving, applying even pressure all around the faucet.
Wet your finger and push the caulk into the crack. Rinse your finger, then smooth down the caulk by running your finger along it again.
