Proper Way To Wash
The proper way to wash your glass is by holding it around the bottom of the glass. If you are handling a stemmed wine glass, do not hold it by the stem because it is a fragile piece that can break easily.
Proper Way To Rinse
Wash your wine glass in lukewarm water with mild dish soap. Hot water can cause the glass to crack. The best way to clean the dirty glass is to use a soft sponge attached to a handle in order to reach tough spots. Make sure to avoid using anything stiff, which can potentially scratch the surface.
Proper Way To Clean
Let your glass air dry by placing the wine glass upside down on a soft towel. You can also use a lint-free cloth to dry off the glass and to prevent any water stains.
Removing Stubborn Stains
Any wine residue can be dissolved using white vinegar. Allow enough time for the vinegar to dissolve the stains, and then rinse the glass with lukewarm water.
