With "Colorguard" in my Hoover TT; it promptly dulled the previously nearly NIB shiny finish of metal tub. Never bothered again.
Yes,historically the only P&G detergent with the full treatment of enzyme cocktail was Tide. However over the past several years Gain and Cheer have been getting better formulas including more enzymes. Previously the best P&G could manage was only proteinase.
