How do polymer beads clean your laundry? Laundry has been cleaned the same way for over 60 years, with a lot of hot water, detergent, and agitation, so new technology is often met with skepticism. But our polymer beads are the product of years of painstaking research and development. Each aspect of the design of the beads, from their chemical composition, to their shape and size, to the amount of beads to be used in each wash cycle has been carefully optimized to ensure a gentle, but thorough, wash. The polymer material reacts with moisture in a manner similar to a sponge and activates the beads to trap dirt and stains from the laundry.
