what tablets do you use? I found the gel ones always did this to my glassware , so now I use aldi’s dishwasher tablets, they look cheap but work wondersI don't mind washing up in the sink because I'm fed up of the dishwasher ruining my glasses leaving cloudy marks on them which don't come off. I've thrown away far too many "spoilt" glasses. We use salt, tablets and rinse aid like it's going out of fashion. Does anyone else have this problem?
or you could have hard water, are you able to use a descalerin your dishwasher?
