I didn't really know if I should post here or not, but you guys seem to be in the kitchen. My glasses have gotten really streaky and have a bluish film on them from washing in the dishwasher. I have tried almost everything on the market that is supposed to help. Not sure what causes that, the dishwasher or the dishwasher detergent, I guess.
Some glasses seem to be affected more than others.
I changed det., now use the tablets, and got new glasses. I don't believe they can be restored, they are etched, meaning the glass itself is damaged. I got a leaflet years ago from my dishwasher manufacturer that described the causes. Too much detergent used with soft water will cause permanent etching. If you have a mechanical water softener, use less detergent.
