With Turbo Clean Technology, this powder detergent whitens whites while using active enzymes to break down and 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 and 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, and it helps to keep the powder fresh and free-flowing.
