How can I make a quality DIY citric acid- based dishwasher detergent?

Hello folks..I'm seeking a quality DIY quality citric based dishwasher cleaner (I've heard and read these are very good, but I will accept all suggestions!) that can POSSIBLY be used to do both things. Clean the dishwasher when empty AND THOROUGHLY CLEAN my dishes when my dishwasher is full. Either way, I'd REALLY love and truly appreciate any and all suggestions submitted!Live in Fl and while I have filtered water, it still is hard water. My dishwasher is a Bosch, left from previous owner, in pristine condition, making it now four years old. I do take care of all my appliances, dishwasher being no exception. I take ALL the necessary steps to ensure the dishwasher remains at its best performance. However, it seems no matter what cleaner I use, a number of my dishes and some glasses come out streaky, gummy and not clean! Gross!!😩 I've checked for trapped "food," all the things that might cause these issues. And the rinse aid as well. Rinse aid was fine. I even tried some vinegar/filtered water sprayed on my dishes before turning my machine on (with the usual detergent in as well). THAT helped somewhat, but not completely. Sigh... I know I'm not alone here as I've read on other sites that others suffer the same if not very similar situations as mine. Now, reaching out to you kind folks and great minds. Would love your suggestions. Thank you kindly in advance!☺
