As I should of stated in my original post, a form of muriatic or oxalic acid is the active ingredient in both On and Off and Starbrite's instant hull cleaner. The difference is that a small bottle of On and Off is something like 2-3 times as much as a gallon of muriatic acid is at the hardware store which is around $8.00 if I remember right. A gallon has lasted me for 2 seasons so far and I believe I will get this season out of the remaining acid.
