Best silver removal method in terms of efficacy and cost is electrolytic system using stainless steel and moving carbon electrodes. The SS electrode will corrode very unevenly if the carbon electrode is not moving circularly around the SS disk.
Although I don't like to heat acidic food in non-anodized aluminium cookware, the whole "aluminium-pan can cause Alzheimer's disease" thing was a malicious rumor made by stainless steel industry in the past. In reality, alum is used in pickling (tho I don't use it), and some baking powders contain aluminium compounds as well. (Note that baking powder is a mixture containing baking soda, but not by itself.)It is not a great idea to ingest huge amounts of aluminum salts, but small amounts are okay. Aluminum hydroxide is one of the ingredients of Mylanta, and it dissolves in the stomach to produce soluble Al(III). Aluminum hydroxide flocculation is a major method of wastewater treatment.
