Can You Put Drinking Glasses in the Dishwasher?

Yes, most drinking glasses are dishwasher-safe, but it depends on the material and finish. Tempered glass, like Pyrex, handles heat well. Crystal, hand-painted, or gold-rimmed glasses can crack, cloud, or fade. Check for a dishwasher-safe label. When in doubt, wash those by hand. Load glasses securely to prevent chipping.

Cloudiness from hard water can be removed with vinegar, but etching is permanent.

Which Drinking Glasses Are Dishwasher-Safe?

Standard soda-lime glass is generally dishwasher-safe. Tempered glass, such as Pyrex or Duralex, withstands high heat and thermal shock. Borosilicate glass also resists cracking from temperature changes. Look for a dishwasher-safe symbol on the bottom. If the glass has no label, check the manufacturer's website.

What Happens to Glasses in the Dishwasher?

Dishwasher detergents can etch glass over time, leaving a cloudy film. High heat can cause thermal shock, especially for thin or cold glasses. Glasses can knock against each other, causing chips or cracks. Silver or gold rims may fade or peel. Crystal glasses may develop a white haze from mineral deposits.

How to Load Drinking Glasses in the Dishwasher

Place glasses upside down on the top rack, not the bottom. The top rack is farther from the heating element. Ensure glasses do not touch each other. Use a gentle cycle with lower heat if available. Avoid overcrowding to allow water and detergent to reach all surfaces. Remove glasses promptly after the cycle to reduce water spots.

Which Glasses Should You Hand Wash Instead?

Hand wash crystal, leaded glass, and antique or collectible glasses. Glasses with painted designs, metallic accents, or decals should also be hand washed. Milk glass and opal glass can discolor in the dishwasher. Any glass labeled 'hand wash only' should never go in. When hand washing, use warm soapy water and a soft cloth.

How to Fix Cloudy Glasses After Dishwasher Use

Cloudiness from hard water can often be removed with white vinegar. Soak the glasses in vinegar for a few minutes, then rinse and dry. Etching from detergent is permanent and cannot be fixed. To prevent clouding, use a rinse aid and lower the water temperature. Consider using a detergent labeled as gentle for glass.
