After years of use, glassware can become etched by minerals in water, alcohol and dishwasher detergents, becoming cloudy. This is also a common problem in vases and decanters where standing water or liquids can etch the glass, creating a dingy appearance. With minimal effort and almost no expense, your glassware will again brighten your dining experience and add elegance to your home.
Fill the item with very hot water and drop in a denture cleaning tablet. Gently stir while tablet dissolves and let stand for an hour and a half. (If you are cleaning several items at a time, fill a container large enough to accommodate them with hot water and add one denture tablet for every 8 ounces of water. Immerse all items in this solution.) Then scrub the etched side with a bottle brush, toothbrush or chopstick with a rag wrapped around the end and rinse thoroughly to remove all chemicals.
Wet your fingers and dip in a baking soda. Rub the soda into the etched areas of the glass until the etching is removed. You may add a small amount (dab) of toothpaste (not gel) if you wish. This works well on light etching.
Use a strong cleaner like Goof Off (not orange scented) or Goo Gone and rub glass using a clean rag. Do not dilute with water. Rub until etching is removed.
Use a metal polish like Simichrome, Wenol or Flix and a clean rag to polish the light etching off. Use cotton swabs like Q-tips or cotton wrapped chopsticks to reach into small areas you cannot reach with your hand.
Use acetone (nail polish remover) on a clean rag to rub etching off of glass.
Soak the glassware in white distilled vinegar for one hour to remove etching.
Hand wash your glass items after removing the etching using hot water and a non-detergent liquid dish soap. Rinse thoroughly and dry immediately to eliminate water spots.
