Anyone who knows me, knows when I go to Florida for the winter, my most missed appliance is my dishwasher. Unfortunately, we have well water which is very hard and for years I suffered with cloudy glasses and flatware...Here is the cure!!!
At the beginning of the cycle, add a package of crystal light or cheap alternative. I use lemonade because it doesn't stain the dishwasher, but any flavor works.
Your glassware will sparkle like new.
the above method works for me...try at your own risk
