Irreversible clouding of glassware

Irreversible clouding of glassware — Glass corrosion

Bosch · Dishwashers

What does Irreversible clouding of glassware mean?

Glassware becomes permanently cloudy, indicating that the glasses may not be fully dishwasher-proof or that wash conditions are too harsh.

Common Causes

  • Glasses are not dishwasher-proof, only suitable for dishwashers (meaning long-term wear is expected).
  • Lengthy steam phase (standing time after wash cycle ends).
  • Program with too high a temperature.
  • Detergent used does not contain a glass protection component.
