We have hard water in our home, and only a couple brands of dishwasher detergent have worked for me. One of those brands is Electrasol Finish Powerball Tabs. These tabs come individually wrapped and need to be removed from the wrapper before putting them in the dishwasher. (I like the pillow type that can be put right into my machine much more). The tablets are blue and white with a red ball on top. These claim to clean powerfully, cut grease, remove coffee & tea stains, clean burned on food and dried-on leftovers, and leave no residue behind. I've had good luck with this product. My dishes come out clean, and there is no residue on my glassware or flatware. My flatware is shiny and my glasses sparkle. I have never had any issues with the detergent not dissolving completely, and they are easier to use than powder. I do rinse my dishes to remove food particles before putting them in my dishwasher. I have found these to work well with or without the rinse aid added to my machine.
