Hello. You can try bar keepers friend. It works very well for me.
What is the pan made of ? Non-stick, stainless steel, copper, etc
Thank you all for your input and help!
Oh, i see. As you have found out, putting those in the dishwasher is a no-no. The good news is that your cookware is probably perfectly useful. The bad news is that you are stuck with cookware that is going to look a little gnarly, and might react with particularly acidic foods.
The anodization process involves building a thick dense layer of oxidation that is crystalline (basically sapphire) which is tough and non-reactive to foods, most of which are acidic, but soluble in an alakaline environment, like your dishwasher.
Normal aluminum oxidation (the chalky white stuff) is a chemically different substance -- it is thin, weak, and washes off. (Consider that graphite and diamonds are both pure carbon -- and otherwise entirely different!) It is easily scoured off, exposing the shiny metallic aluminum beneath. Metallic aluminum is soft and reacts with foods -- not a good thing for cookware.
Anodization involves sulfuric acid dips and a healthy source of DC power -- way beyond a DIY project. If you know somebody in the curtainwall business, they might be able to sneak your pots onto the line. No guarantees that you will have something safe for cooking food, but it will look nice.
If having ugly cookware drives you nuts, or if it is misbehaving (turning your mashed potatoes a lovely shade of grey, for instance), then chunk it and start over. Otherwise, relax and cook 'em into the ground.
