Because of its chemical make-up, you want to make sure you don't get plumber's putty on any finished items. In fact, plumber's putty, detergents or abrasive cleansers will void the warranty on the finish. Read the limited warranty on your nice chrome faucet if you don't believe this. This is why they call it a limited warranty. The best way to keep your warranty intact and your finishes in shiny shape is to use non-abrasive, non-corrosive cleaners and a soft cloth for polishing and routine cleaning.
