Everything in glass gets like this when I put them in the dishwasher, everything else is cleaned like normal. I'm using rinsing aid and dishwashing salt as recommended. I know the water where we live is rich on lime (limestone) so I don't know if that has something to do with it? We got this dishwasher a year ago and it's been working fine until now. I have used those cleaning tablets for the dishwasher too bit it did not make it better. Any advise?
