Powder detergent whitens whites while using active enzymes to break down & help remove stains. Quick-dissolving formula immediately starts dissolving even in cold water. Nonchlorine, oxygen-based bleach along with a unique bleach-activating system gives Ultra Tide with Bleach its effective, color-safe bleaching performance & leaves clothes virtually residue-free. The powder detergent actually reduces chlorine in the wash to help keep your colors from fading. Tide plus Bleach is also concentrated with more stain-fighting power so you can use 1/3 less. Moisture-resistant carton means no worry about clumping, & it helps to keep the powder fresh & free-flowing.
