My husband does absolutely nothing involving the dishwasher except unloading it. I load, clean and manage the supplies for the dishwasher. Currently we are making our own Dishwasher Soap Powder. We love it and I will never go back to store bought, mostly because of the cost savings. What I did not have and found in the book by Karyn Siegel-Maier was a rinse solution. I have used vinegar to clean the dishwasher and remove residue, but I never thought of using it int he rinse container. Here are two items to use so you can avoid buying rinse agent (like Finish) with something you probably already have in your kitchen!
. I recommend a lemon herbal vinegar to give it a great scent too!
