All GraMonty glasses are dishwasher safe and when properly loaded, can withstand at least 2,000 dishwashing cycles with no demonstrable change to their shine or clarity. We recommend to wash the glasses in hand with hot water and a soft scrub brush one time every year to maintain the clarity in the glasses.
Dishwasher approved:
– Only place the glasses in the dishwasher with bottoms up.
– Temperature/cycle selection: You should select a low-temperature cycle (50 – 55°C) when washing glass or, if available, a special glass cycle.
– Steam: After rinsing, you should open the dishwasher door briefly to allow moisture to escape, as water vapor can accelerate clouding of the glass surface.
– Washing glass and household utensils made of aluminum (e.g. garlic press, pots with aluminum handles, etc.) together should be avoided at all costs.
– Non-dishwasher safe materials: Avoid washing non-dishwasher-safe materials, e.g. aluminum and stoneware. This causes chemical reactions between the aluminum and the glass surface, which can extremely accelerate the clouding process of the glass.
