I don't get it.
I'm not suggesting that you should store soiled pots and pans or not properly care for your investment.
But why do so many people get upset about stains in the bottom of a dutch oven or minor discoloration on copper? It's cookware for crying out loud. Signs of use are inevitable if - GASP! - you actually cook with it.
Take a deep breath, folks. It's just a stain. Your friends and family still love you.
