Dishwasher causing patterns to fade on glassware

It is disappointing when you notice that the pattern or colour of your favourite glasses are fading. You will really become aware of this if you compare an older glass with one you have recently purchased.This fading is usually caused by one of the following or, more likely, a combination of all three:

  • Very soft water – unfortunately there is very little you can do about this, as it is purely down to where you live.  However, if you do live in such an area you should not add salt to your dishwasher, as this will only make the water softer.
  • Detergent overdosing – if you use a loose powder detergent you may be overgenerous, and can actually cause more harm than good if you put too much into your dishwasher.  If this is the case, you may find it a better option to switch to a good quality tablet or gel cap, as this type of product will always give you an even dosage of detergent.
  • Poor quality glassware – this last point is probably the most telling.  There is nothing wrong with this type of glassware, but it will certainly mark over time, and, in this case, patterns and colours will fade.  Most of us have two or three collections of glass that we use, generally being one for best, one for guests and one for everyday use. 

Unfortunately once the pattern or colour starts to fade, there is no way to regain the original finish.  If you do like patterned glassware, it is recommended that you purchase a better quality and ensure the product is dishwasher safe.
