Do you happen to know..
what acid is listed, or, can you point me to where it is listed?
The Thing is.. the formula for the "fryer boil out* & *cascade institutional* both contain a Chlorine Additive, that breaks down into Chlorine Bleach. And when Chlorine reacts with Acids.. it releases a dangerous gas called "chlorine or mustard gas".
If they did place an acid in the product, there would be quite a horrible reaction, imo. Although, I can't seem to find a acid listed in the "Material Safety Data Sheet" or MSDS (where it would be listed).
As for Chlorine. It does seem to be safe, for use on stainless steel.
