Ron:
I'm sorry, I did not mean to give the impression that I was recommending oven cleaner for Club. It works very well on Farberware and Corning Ware, which are my preferred cookwares, but Club is all aluminum, which is different. My apologies.
I'd like to speak to the "aluminum-cookware-causes-Alzheimers" meme. I have a lot of professional background in cookware, cooking and nutrition, and this controversy was very big at the time I was in the business. After considerable research, and talking with some people at Emory University (a med school), I found three things:
A) No causal link has ever been found between aluminum ingestion and Alzheimers. None.
B) The amount of aluminum one gets from cookware varies very drastically according to the cooking method. Frying in fat causes almost none, for instance. Cooking acidic foods can cause more. Storing acidic food in aluminum can end up putting a lot of aluminum into the food, like shoving a pot full of leftover spaghetti sauce into the fridge.
C) Aluminum is very difficult to avoid no matter what you do. It's in deodorant, packaging materials, all kinds of things. It's also naturally present in agricultural soils of certain regions, like Alabama, where the soil is rich in bauxite, the ore from which aluminum is derived. Quick - is that an Iowa onion or an Alabama onion in the produce section of your store?
My recommendation to cookware customers was always to avoid cooking high-acid foods in aluminum if they had concerns, and never to store food in the cookware. So far as I know, they all still remember this advice.
