What cleaning products should I stay away from while cleaning my Kingston Brass item?

Kingston Brass recommends that you only clean your faucet with a mild non-abrasive soap (hand soap). If you notice calcium or lime buildup, we suggest that you use a half-and-half solution of one-part warm water, one-part vinegar, and a washcloth. Do not use any harsh or abrasive items to wide down your KB item.
