Give your sink a good scrub too. Wet it, sprinkle a little baking soda or my Nightly Sink Scrub (found here) into it, and scrub the surface with a sponge or scrub brush. Add a squirt of dish or liquid castile soap, scrub a little more, and rinse thoroughly. Spray and wipe your faucet, and dry the sink. Baking soda is gentle yet abrasive and can be used for any sink surface.
