Dishwasher Rinse Aid contains special low foam wetting agents and additives which work best at low concentrations to provide excellent high temperature rinsing, and ensure streak free and taint free results.  It is especially effective when used in conjunction with Wonderwash Dishwashing detergent, which together provide a range of products for all your dishwashing needs. The special formulation of Dishwasher Rinse Aid effectively reduces the surface tension of the water to allow easy rinsing, ensure rapid drying, and eliminate the problems of water spotting. Rinseaid is used in the final rinse at working concentrations of approximately 3ml per 5 litres of rinsing water, but the exact concentration should be individually adjusted to your machinery to give a streak free and spot free finish.  The optimum temperature for best results is 80 deg C.
