Perfect glasses and crystal glassware, even in the summer sun

Using the dishwasher with Nuncas

Glass and crystal are materials that might seem easy to keep clean; however, if you mess up the washing routine or dry them in the wrong way, it is easy to end up with streaks and spots. Conversely, it takes just a few simple steps and the right advice to keep them in perfect condition.
The French have a beautiful name for all objects made of glass and crystal that are normally displayed in a cabinet: verrerie. Delicate and transparent and with a unique, simple beauty, some objects are used regularly, possibly even on a daily basis, while others are unique collector’s items displayed in glass cases, or maybe just elegant items that are only used on special occasions. In any case, when it comes to cleaning these items, you may not always feel secure about washing them in the dishwasher.
However, there’s good news: using a dishwasher is definitely safe (provided it has a special programme for washing crystal and glassware), you just need to choose the correct detergent and take a few precautions when loading the machine.
Load the dishwasher by putting the glasses upside down on the appropriate racks. Make sure that crystal items are not touching, as the vibrations of the dishwasher during the wash cycle could break them.
Then choose a liquid or gel detergent to avoid scratches and always use just a little: dose the detergent according to amount of dirt, not according to the number of dishes to be washed. You may not be aware that detergent attacks dirt in a specific way, and when it doesn’t find any, it attacks the surface of the dishes instead. Therefore, if you add too much detergent you risk ruining your precious crystal glassware.
In any case, do not use detergent tablets, especially the “three in one” tablets, as they break into small pieces when they come into contact with water, which are dispersed throughout the machine by the jets of water, creating scratches on delicate surfaces. Nuncas recommends its Dishwasher Powder Detergent, which is ideal for items that require careful washing, thoroughly sanitising them and eliminating any lipstick stains that often remain on glasses.
Finally, a useful note on rinse aid. This product should be always used to avoid any opaque rings remaining on the dishes. Of course, the dosage depends on the hardness of the water in your home. Every modern dishwasher allows you to control this (if you use a detergent in tablet form, you can’t because it is pre-dosed). As part of its range of products for washing dishes, Nuncas offers Nuncas Rinse Aid, an excellent rinsing product that leaves your dishes bright and shining.
For glass, drying is just as important as washing. The dishwasher cycle ends with a jet of steam at 90°C, which dries the dishes evenly. At the end of the wash, it may be useful to open the door slightly to allow the steam to escape and prevent the accumulation of residue (some more technologically advanced dishwashers do this automatically when the drying cycle has finished).
If you want to wash your crystal glassware by hand, perhaps because you don’t have that many items, you should keep them separate from any greasy pots or dishes. If you put the glasses in the same water as greasy bakeware, you will have to wash them more aggressively than you normally would to remove the dirt that usually accumulates on glassware.
Wash crystal glassware with a soft sponge, rinse them thoroughly and then allow to drain for a few minutes upside down on a clean cloth. However, you should dry them by hand with a lightweight linen or cotton cloth (washed without fabric softener!) as, naturally, if you leave them to air dry, they will be covered with limescale marks. Finally, carefully put the glasses away, preferably without stacking to avoid scratches.
This will help you ensure a long and shining life for your crystal glassware.
