The only thing listed in the msds for the pre bleach is edetic acid at 1-5%. Is this one of those precursors? The bleach lists potassium nitrate and ammonia. They have renamed the last step from "conditioner" to "final rinse", the pre bleach is now "pre bleach 2" and claim the process "creates a safer and more user friendly working environment". I'm curious to know if I need to use the separate stabilizer.
