In the dishwasher

  • Rinse your glasses with clean water.
  • Be careful that the glasses do not touch each other to avoid possible stains.
  • Add dishwashing liquid and shine liquid.
    • Personalised printed glasses like non-aggressive detergents.
    • Soft water removes marks better than hard water. The softer the water, the less detergent is needed. Adjust the dosage according to the water hardness of the local conditions.
  • Use the "Glasses" programme (max. 50°C) and a short rinse cycle.
  • Once the programme is finished, do not open the dishwasher completely so that the hot steam can escape. This prevents the formation of drying marks.
  • Allow the glasses to cool before use.
  • Wipe your glasses with a clean cloth to avoid limescale residue.
