I've been using these tablets for years since I discovered there were many harsh chemicals and bleach in most major brands. There's no need to have such harsh ingredients to wash your dishes in and to add to contaminating our water supply. These tablets do a great job of just cleaning your dishes period. Nothing special or fancy about it. You need to know the hardness of your water to know how much detergent your automatic dishwasher needs (refer to your user's manual). For us, we break a tablet in half and that seems to do the job. How hot your water is is also a big factor to how clean your dishes will get.
