Everything about my order, the shipping and how the pot looked when it arrived was perfect. The only problem I have is that when I wash it with warm, soapy water and then dry it with a cloth or paper towel, I see a grey powder on the towel. I haven't wanted to cook with it until I no longer see the grey powder coming off the pot because I think it will end up in my food. Have you had any experience with solving this problem?
