Don't know from Clorox detergent
But there was a dry Clorox bleach that one just loved! Bought ever single box could lay hands on when heard it was being discontinued.
It was an activated oxygen bleach and (IIRC) contained enzymes. Am here to tell you the stuff whitened like no one's business in warm or hot water. Kicked things up to very hot or boiling and whoaaa Nellie!
