Does Aqua-Rex work on the Dishwasher?

The answer is no! The pump in the dishwasher reduces the effectiveness of Aqua-Rex so you need to use a good hard water detergent and most importantly a hard water rinse aid, such as Lemishine which is available from most stores. If you follow these instructions you should be happy with the results from the dishwasher. Laundry washing machines work better with Aqua-Rex.
