All cutleries need some care to maintain their original finish. Rinse cutlery after use to remove any scraps of food, even if you plan to wash up later. If you use a dishwasher, choose a shorter cycle and dry the cutlery by hand. That way you avoid rust spots caused by food that sticks to the cutlery, or by leaving cutlery too long in the hot, humid air inside the machine. Good advice doesn't have to be expensive.
