Clean cloudy glassware by soaking the pieces in vinegar, trying acetone and determining the source of the cloudiness. If the cloudiness doesn't come off, it might have resulted from etching. While etching cannot be removed, it can be prevented from worsening.Continue Reading
Place the glassware in a bath of distilled white vinegar. Let it soak for 5 minutes. Remove the glasses, then wash them with a mild detergent and dry with a lint-free cloth.
Acetone, which is found in nail polish remover, is also effective in removing cloudiness from glassware. Using a soft cloth, apply the nail polish remover to the cloudy items. Rinse, then wash with mild detergent and dry with a lint-free cloth.
If vinegar and acetone do not remove the cloudiness, consider what the cause might be. While cloudiness is commonly caused by a buildup of detergent, it can also be caused by etching. Both hard water and too much detergent can both cause etching on glassware.
To stop etching from worsening the cloudiness of your glassware, use less soap when washing dishes and avoid washing dishes before placing them in the dishwasher. Modern detergents require contact with food particles to work properly, and the absence of food means the detergent works on the glassware instead. Also consider switching to a detergent that includes few or no phosphates in its ingredient list.
