Kathy – Thank you for your inquiry. Tide is, and always has been, a superior detergent with high quality performance. An in-wash booster gives Tide the opportunity to use complementary, high-quality stain fighting ingredients that are not compatible with detergents to boost the already high performance of Tide. In addition, Tide Stain Release will boost the performance of any detergent, giving more people the opportunity to experience great stain fighting results.
