Seventeen states banned phosphates from dishwasher detergents because
the chemical compounds also pollute lakes, bays and streams. They create
algae blooms and starve fish of oxygen.
But dirty and damaged dishes are turning many people into skeptics, including Wright.
most of the people use phosphate because phosphates are wonder ingredients. They not only strip
food and grease from dishes but also prevent crud from getting
reattached during the wash. So she says without phosphates, people have
to wash or rinse their dishes before they put them in the dishwasher,
which wastes water. Or they run their dishwasher twice, which wastes
electricity.Dish detergent makers changed their formulas because of environmental
concerns, and the ingredient that had to go just happened to be the
industry's chosen grime-fighter.
