My glasses always go cloudy and streaky in the dishwasher. I know this is likely to be our limescale-y water - we live in an area with high limescale - and I don't know how to prevent them. I've googled, and always make sure the salt dispenser has plenty of salt, I've set the dishwasher's water softening system according to the water company's published hardness of water, we even use 5-in-1 tablets so there is even an extra dose of salt.
What more can I do? Am I doomed to wash them up by hand?! The dishwasher instructions mention dishwasher-proof glasses - do they really work?
Help!
