As I said, the "Oxyclean" stuff is sodium hypochlorite with potassium
hydroxide (according to the MSDS). Not what you want to use on your
gear.
Interesting that the process involves a generated component,
peracetic acid, however. I use PAA (made with acetic acid, hydrogen
peroxide and sulfuric acid) to clean lead stains from silverplate. I
wonder if the raw stuff would work as a de-yellower instead of
depending on TAED?
