If you don't want your crystal glasses to lose their shine and become dull, you should follow simple rules when washing them.
So, if you prefer manual cleaning, glass items should be immersed in a large plastic container.
The bottom of the bowl or basin should be lined with a towel - this will minimize the risk of breakage of the dishes.
The temperature of water for washing crystal should be 40 degrees. If the liquid is cold, the products will certainly become dull, and because of boiling water they can burst.
When washing glasses and goblets, do not hold them by the stem – this is the most fragile part of the product. Instead, firmly grasp the bottom at the base of the bowl.
If there is gilding on crystal glassware, you should only use vinegar, previously diluted with water.
In the same case, if metal decorative elements were found, avoid soaking the dishes for a long time, which can cause rust to appear.
Don't neglect the final step of cleaning crystal, which is to dry all items using a cotton towel.
