Post a pic of your pot please, that will help determine the best method.I bought a fairly expensive pot online and when it came i was a bit disappointed because it had more shine than I wanted. I wanted it to be matte. I read there is a special type of towel being used for this purpose. Does anyone know what I do to help this pot be more beautiful in my eyes?
You could try muriatic acid. Pro method would be sand blasting. Agree with leaving it outside and it will get less shiny on its own.
