Why did Cascade take phosphates out of the formula?
Cascade products complied with all local, state, and federal regulations that required the removal of phosphate from all automatic dishwasher detergents by July 1, 2010.
What did phosphates do?
Phosphates helped with dishwashing performance by facilitating food removal and removing the calcium that binds these types of foods together. They also helped control water hardness and suspended soils within the wash water so they did not redistribute onto dishes.
Can I still use my old Cascade product?
Because phosphate laws vary by state, please contact your state environmental agency for information on what to do with any phosphate-containing Cascade product you may have.
