If you live where you have hard water then this is for your dishwasher. Lemi Shine will remove spots and film from your dishes, and glasswear. The hardwater build-up in your diswasher will be removed as well. It is suggesed that you run alittle Lemi Shine through your dishwasher before you load your dishes or glasswear. Then load dishes and follow directions, and wash with the Lemi Shine, and your favorite dishwashing detergent. There is also a Lemi Shine with Lemi Shine rinse included, but i haven't seen it around here.
The container holds about 12 oz of detergent and does around 18 loads of dishes. The detergent has a lemony scent., and is also Phosphate Free. The product also comes with a money back guarantee, Can't get any better than that.
We use this because we have well water and our dishes look terrible. Have been using this for about a year and can say our dishes and glasswear are looking much better. It can become costly, but we really find it worth the money. Here where we live, I can sometimes find it at Wal Mart, but i have also been able to find it at Target in the dish detergent isle.
