Since July, people have been wondering why their dishes are not as clean . . . Now, over 7 months later, people are becoming more aware of what the problem is, and it isn’t because of their dishwashers. After studies showed that one of the key ingredients in dishwasher, phosphate, was leaking into rivers and reservoirs, decreasing oxygen for fish and plants, environmentalists took a strong stand to ban the compound from detergent.
Forced to respond to a law that passed in July for 16 states, companies like Proctor and Gamble (Cascade) went back to the drawing board to create a working product that was phosphate-free.
The film that you now see on your dishes after washing them in the dishwasher is due to the environmentalists banning phosphates in your dishwashing detergent. 16 states have banned phosphate, including Indiana.
Want to fix the problem? The ban applies only to consumer based detergent, not commercial, so buy a commercial dishwashing detergent. Or purchase phosphate online and add it to your dishwashing detergent.
