Following what I thought I read as the advice on the Dish-washing Detergent Package, I was dropping the packet on the bottom of the bottom of the dishwasher.
After washing the dishes, the dishes looked worse than they did when they went in. Streaked and in some cases greasy. Glasses and silverware were coated with a white film.
After asking others about how their products worked, they all said, wonderful. I asked how many packets they used, and most said one. One said one packet in the closable detergent container. Problem solved.
I am sure no one has ever done this except myself, but thought I would mention it, if your dishwasher is performing a little less stellar than you would like. Problem solved.
