Some normally law-abiding people in Spokane, WA have become dishwater detergent smugglers. Spokane County launched the nation’s strictest ban on dishwasher detergent made with phosphates last July. The ban is aimed at a reduction in water pollution and will go statewide in July 2010.
Many people complain that eco-friendly products leave their dishes dirty and greasy. Hard water is mineral-rich and resistant to soap. Phosphates help to break the minerals down.
I use an eco-friendly detergent in my Asko dishwasher and have no complaints. Maybe these individuals’ complaints are related to water quality that needs to be addressed by an in-home filtration and treatment system, so the water is soft before it enters the dishwasher.
