Consumer Reports finds how to get glassware crystal clear in the dishwasher

Frustrated by filmy buildup on your glasses? Consumer Reports put clear dish ware
through its tough test with very hard water, and it came out coated with a white film. In
hard water, glassware is 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 Finish Power Up. Consumer
Reports tried Finish Power Up according to the manufacturer’s instructions, putting it
in the prewash dispenser. But dispenser sizes vary, and the dishwasher Consumer
Reports used didn’t hold enough to get the job done. There was not much difference
before and after washing with Finish Power Up.

Then testers used the alternate
instructions, which say 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. Though you may have to experiment with how much to use,
it also worked.

In fact, all three products ultimately worked. Consumer Reports says the Lemi was the
least expensive and the best value.

Consumer Reports cautions not to use Finish Power Up or Lemi Shine with a detergent
that contains bleach. Both are acidic and may produce toxic gases if mixed with bleach.
