Cascade Complete is a dishwasher detergent made by Procter & Gamble. It is available in both powder and gel form, and claims to be effective at cleaning dishes even in hard water. Hard water is water that has a high mineral content, which can make it difficult for soap to lather and can leave spots on dishes. Cascade Complete contains phosphates, which help to remove minerals from the water and prevent spotting. It also contains enzymes, which break down food particles and help to remove stains.
