Copper. All of our cookware has a low-maintenance brushed copper finish. However, normal usage can cause any copper cookware to discolor and tarnish. To keep your cookware looking new, we recommend occassionally using a non-abrasive cleaner such as Bon Ami and a nylon pad on the copper vessels. Plain dishwashing soap and a sponge should work for normal cleaning purposes. For tougher stains, try a paste of equal parts ketchup and salt. Polish occassionally with Flitz Polish.
Stainless steel. Never dissolve salt on the surface of any stainless steel as it can cause pitting. If cooking pasta in our cookware, we recommend adding salt to the pot after it comes to a boil and rinsing the pot out immediately after use. Our warranty does not cover pitting from excessive salt exposure.
Cast iron. Alway dry cast iron immediately after washing and do not leave it soaking in water as it will rust. If you wish to cure the Classical Line handles, you can apply a small amount of vegetable oil to the cast iron (try avoiding the copper) and place in a 250 degree oven for 30-40 minutes.
