Cycle-2 detergent is a light amber liquid laundry detergent concentrate for use in hot or cold water. Cycle-2 is the result of the latest technology in surfactants and emulsifiers; materials that were designed to work equally in hot or cold water. Because of Cycle-2's excellent water conditioning, stain removal and rinsing properties, linen that was once gray or yellow becomes white again. Cycle-2 is safe on wool and silk.
