Query: TSP got my dishes clean again

I was frustrated with filmy and poorly cleaned dishes since the ban on phosphates in dishwashing detergent. I bought the TSP to add back the active ingredient to get my dishwasher working again. It works great! the dishes come out spotless and the inside of my dishwasher even looks and smells cleaner. It only takes a little less than a teaspoon to get it to work so the one pound box should last awhile.
