What does dishwasher rinse aid do?

Before we show you how to use dishwasher rinse aid, let’s look at the science behind it. Sometimes our dishes come out a little less sparkly than we would like, which is usually because food and drink particles have circulated inside the dishwasher, ending up back on dishes, glassware and cutlery and the end of their cycle.

Our Finish^® Rinse Aid uses “surfactants”, reducing the surface tension between the water and glass to ensure that when it slowly evaporates, it doesn’t leave anything behind.
