Recently my dishes have been coming out of the dish-washer with a lot of white powdery-crust all over them. It's extremely hard to scrub off and often the only way to remove it is to soak them in vinegar.
What could be causing this and how do I fix it? My dishwasher is less than 6 months old.
I have tried jet-dry and have been using the little two-pack tablet things that dissolve in the dishwasher (seems to give me the best of all the bad outcomes).
