I have recently done some research on different additives to combat with hard water in dishwashers, causing mineral build up, and filmy dishes. With that said, threw all the products I tried, Lemi Shine Was the Best for the environment, Best priced, and Most effective. If you are having issues with your dishwashers ability to clean your dishes, I would Highly recommend this product.

I do not work for them, and am simply trying to inform consumers of an excellent product.
