Dishwasher salt is designed to soften hard water in order to prevent harmful lime scale. This is very important if your home is in a rural area as lime scale can damage your dishwasher and dishes. Miele dishwasher salt is made to go into the water softener of any brand of dishwasher. It dissolves during the cycle and leaves no residue.
We have looked for a reliable supplier of salt for the dishwasher for a long time. Then we found McHardy on line. The Miele Salt supplied worked very well. It was also reasonably priced and delivered quickly.
