Q: What is Dishwasher Rinse Aid Used For?

A: Dishwasher rinse aid improves results by:

  1. Assisting in the drying process
  2. Protecting glass from marks or etching
  3. Reducing the occurrence of white spots on glassware.

This is where things get a little technical. Rinse aids reduce the surface tension of water used during the cleaning and rinsing cycles. Reduced surface tension means the water droplets lay flat on your dishes as opposed to being more rounded.

As a result, the water is exposed to more air and evaporates more quickly. Because the water sends less time sitting on ur dishes, those pesky white spots are less likely to occur.
