(WMC TV) - Dishwasher additives claim they can help with spotting and filming on glassware and dishware. Consumer Reports tested an array of them.
Testers tried Finish Power Up according to the manufacturer's instructions, putting it
in the pre-wash 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 Finish Power Up's alternate instructions, which advised putting it directly into the machine. That time, the dishes came out looking clean.
Testers also tackled Glisten Dishwasher Cleaner and Hardspot Remover, which comes in
pre-measured packets. It took two cycles to remove the residue. Not good.
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 worked very well.
Consumer Reports said the Lemi was the least expensive and the best value.
But a warning: Consumer Reports cautioned 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.
