GA I also use Finish Quantum and agree it is the best.
The glasses I'm trying to get the spots off of came from my aunt. Maybe if I run them through the dishwasher a few times with Finish Quantum, it will clean them up. For now I have them soaking in vinegar and water. I called Replacements.com and they said vinegar would not hurt them.
Oma, If I ever get this off here I will let you know what product did the trick.
try soaking them in a pan or bowl with false teeth cleaner....just follow the directions for cleaning false teeth. i did this with old glass bottles when i was collecting and selling. it did a great job on them.
change your rinse aid. ALways use jetdry NOT the cheap ole stuff. Using dawn dish soap on them is one of the best ways. Also use cascade. Clean your dishwasher with the a 1/4 cup of oxy clean and bleach.
