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.

When preserving

Pasteurisierung

  • Wash and preheat your jars, seals and disposable lids before use.
  • Pasteurisation is easily done with a pot of water or a "steriliser" with a thermostat (75°C).
  • Store at a low temperature.

Sterilisation

  • Choose lids that are suitable for high temperature sterilisation.
  • Wash and preheat your jars, seals and disposable lids before use.
  • Sterilisation is carried out with a pressurised device that can reach a temperature of 116-140°C.
  • Store at room temperature.

In general, you should make sure that your jars are filled correctly:

  • The fill level is indicated on the technical drawing of your jar, or fill it up, making sure to leave a 10% gap.
  • The fill level is always indicated for a temperature of 20°C.
  • When filling, make sure that all filling heads work properly to guarantee the volume defined in the technical drawing.
  • Temperature shocks are to be avoided (maximum 40°C).
  • Bottles like to be stored vertically.
