Suma Select A7 is a concentrated neutral rinse additive. It has been specially formulated for use in a wide range of ware washing machines. The special blend of non-ionic surfactants is designed to lower the surface tension of the final rinsing water. This prevents droplet formation, and because the water sheets off the surface in a thin layer, drying times are also reduced. This special blend also prevents heavy foaming in the dishwash machine.
