Like pretty much everyone posting here, this caused a white film over our dishes and dishwasher. I can't believe this is still on the market! Too bad I didn't research dishwasher fluid before I bought it.. who does unless it is on-line.Anyway, if you are here.. you now have info that the rest of didn't have before we bought it used and had to fix the problems it caused.
