Guidelines for washing in the dishwasher:
Always use the dedicated glass-program of the dishwasher (either with the stemware icon or temperatures below 55° Celsius) and follow the instructions of the manufacturer.
The glasses have to be fixed properly to avoid falling on other objects or hit when the water pressure can move them during the washing
The dose of chemical has to be kept gently low to avoid overdoses. Tabs usually contain all additives so others like rinse agent are obsolete and can damage the glasses when still in the tanks. Phosphate-free detergents have to be avoided because of the aggressive substitutes.
The glasses should not be exposed too long to the hot steam once the wash cycle is over. Open the door a bit to let the steam out.
In general, we have to say that for all wine-glasses, the stem is usually the most critical and sensitive part. Though the bowl should be handled gently especially from inside to avoid high pressure (e.g. because of excessive use of a brush or inserting a sponge). Usually rinsing with hot water and careful polishing with a microfiber-cloth is sufficient.
