Permanent clouding of glassware in the dishwasher

The appearance on this effect on your glassware will be milky striations, swirls and rings.  The reason for these marks is that not all glass is of the same standard, and there can be weak spots in the glass which can be damaged after many cycles in a dishwasher.  Unfortunately, these marks are permanent and cannot be removed.The causes of this damage can include:

  • Composition of the glass.  Some glass is of a poor quality and cannot stand up to high temperatures experienced in a dishwasher cycle.  Some glasses were not made to be washed in a dishwasher, and are subject to damage.  In order to avoid this in the future, ensure you purchase dishwasher safe glass, and the best quality you can afford.  This should avoid a re-occurrence of this effect.
  • Soft water.  If you live in a soft water area, you do not need to add salt to your dishwasher, as this may well exacerbate this situation.  You can check with your local Council if you are unsure if you live in a soft water area.
  • Dishwasher detergent.  It is essential you use the correct dose of detergent for each cycle that you use.  Recheck your manufacturer’s handbook for guidance on the doseage you should follow.
  • End of cycle.  It is always a good idea to remove glasses from the dishwasher as soon as you can, but as this is not always convenient an alternative to this is to open the door slightly at the end of the cycle, as this will allow the glasses to dry quickly.
  • Low temperature wash.  It is recommended that glasses are washed at a lower temperature, but this is not always possible.
