I guess I have two questions: what is my problem? and how do I fix it? All of the dishes in my new house (its an old house, I'm renting...) come out of the dishwasher with a white chalky substance all over it. It rinses right off but then as it dries you can see the white (calcium?) substance reappear. Just today I tried hand washing all the dishes to see if the problem was with the dishwasher and the white stuff is still there. So it seems like the obvious answer is that I have hard water and need to get the landlords to get a water softener (that should be fun). Here is where it gets tricky though. The guys who live in the apartment downstairs do not have hard water. Is it possible that we live in the same three floor house and only one of thee floors has hard water? How should I fix this? Thanks for anything you guys can do.
