THIS MAGNIFICENT LOOKING SINK IS HIGH MAINTENANCE FOR STAINLESS STEEL; WATER STAINS APPEAR EVERYDAY IF NOT OILED DOWN AND NOW THERE IS A DISCOLORATION IN THE BOTTOM OF THIS SINK - DIRECTIONS STATE THIS SINK CAN ONLY BE CLEANED WITH SOFT CLOTHS AND DISH SOAP, NO HARSH CHEMICALS OR ABRASIVES WHICH WE HAVE NEVER USED, BUT STILL THE WEIRD DISCOLORATION APPEARING ON THE BOTTOM OF THE SINK. ALSO THE WATER MARKS LEFT FROM A BOTTLE OF HAND SOAP LEFT ON THE LEDGE  JUST FROM USING THE FAUCET ARE UNSIGHTLY AND SO WE CAN PUT NOTHING ON THE TOP LEDGE OF THIS SINK AND MUST RUB OIL ON THE TOP EDGE TWICE A DAY TO PREVENT WATER STAINS-SEEMS A BIT INCONVENIENT SINCE IT IS A SINK AND WATER AND SINKS GO TOGETHER, NO?
