Our rinse aid powder is the perfect complement to our dishwasher tabs or dishwasher powder and our dishwasher salt. Rinse aids form a protective barrier between the crockery and the food. This prevents food and mineral particles from reattaching to the dishes and the dishes are clean from the very first rinse. The rinse aid also disperses the remaining water droplets at the end of the wash cycle so that the dishes can dry quickly and no streaks or water marks form.
