Since I had the suspicion that it is 2nd choice. This would however be declared and it was not.
Even after the first rinse in the dishwasher (relatively new machine) they came out with a veil. It could be, of course, that my dishwasher is eingetellt wrong for these glasses (Härtgrad / amount of salt) .But my other glasses that is never the case. However, someone has given the hint that for production reasons sometimes can make a Schmirfilm with new glasses that goes away only after repeated rinsing.
After rinsing by hand, it was gone.
I hope that my acquaintances the glasses still can replace easily.
