I'm sure we've discussed this on KT but I wasn't having the problem at that time.
We have the same everyday glassware at home and at the condo -- cheapie Big Box stuff. When we got home I noticed that our glasses are NOT CLEAN -- cloudy, ring marks (from milk?), smudged along the edges (lipstick?). At first I thought the house-sitter had let things sit for days without running the dishwasher, but nothing has improved after two weeks.
I ran a vinegar rinse through the dishwasher and checked the trap. I'm still using Cascade Complete and Jet-Dry rinse aid. I've tried a longer cycle -- nothing helps.
I was able to clean two glasses using CLR, but that seems drastic. Is my dishwasher broken (12-yr-old Fisher Paykel dish drawers) or is there something I can try adding to the detergent? (Neither drawer gets these glasses clean.)
