I believe this is a necessary maintenance product therefore we have a dishwasher, to extend the life of it (scaling), and keep clean. I use it once a month since I have my dishwasher: it is a powder that is poured into the tank for the tablet when the dishwasher is of course empty. Then starts the intensive program for optimal efficiency. Result: My dishwasher is always clean and never bad smells! I hope I suddenly last long. Thank you Amazon, because these products are the same as those found in supermarkets, but cheaper. So that now I command them systematically.
