When you set a table for a nice meal, you'd never want to use cloudy glasses
like this.
Consumer Reports put clear dishware through its tough test with very hard
water, and it came out coated with a white film.

"In hard water, glassware is even more likely to develop a film. And since
polluting phosphates were banned from detergents two years ago, the
problem has gotten worse."
Dishwasher additives claim they can help, including this one from Finish.

"Add Finish Power Up to boost your detergent, and you'll see a huge
difference."
Consumer Reports tried Finish Power Up according to the manufacturer's
instructions, putting it in the prewash dispenser. But dispenser sizes vary,
and this one didn't hold enough to get the job done. Here's before and after
washing with Finish Power Up. Not much difference.
Dan DiClerico,
"We decided to use the alternate instructions, which said to put the Finish
directly into the machine. That time the dishes came out looking clean."
Next up - Glisten Dishwasher Cleaner and Hardspot Remover, which
comes in premeasured packets. It removed the residue after two cycles.
Then there is Lemi Shine Original. Its instructions say to use it to clean the
machine first - then with the dishes. While you may have to experiment
with how much to use, it also worked. Here are the dishes before and after.
Dan DiClerico,
"While all these products ultimately worked, the Lemi was the least
expensive and the best value." ."
