TK--- Not off hand. I do know he does not believe in clay baths for chelating. Aluminum levels will usually go down after removal from exposure and during the process of chelation without any particular treatment. If they are very high there are some things in specific you can do to help, can't remember them at the moment so if someone wants to chime in please do.
TK, do you know if Andy has ever commented on the possibility of aluminum being absorbed from a Pascalite clay bath?
