A while back I was really concerned about my nice dishwasher not getting the dishes as clean as they should be getting so I did some researching. If you have a water softener in your house like I do there are some important little tips you need to know.
1. Don't give your dishwasher very much detergent! I have dumped some cheap detergent into a little upcycled plastic and added a baby spoon for measuring. You need about two heaping baby spoons in the main wash side and another one heaping spoon for the other side. That's all no more! If you use more and fill your soap dispensers up your dishes won't get clean.
2. Use some blue juice in your machine! Purchase an inexpensive rinsing agent and keep it full according to the manual. This will keep things shiny and clean as well.
Follow these two simple rules and see if you notice a difference. There will be a lot less rinsing ahead of time. Happy Dishwashing!
