How to Restore Cloudy Glasses from the Dishwasher

Cloudy, etched, or foggy glasses can be a frustrating result of dishwashing, but there are ways to restore them to their former clarity. Whether your glassware is suffering from hard water buildup or permanent damage, we’ll guide you through the steps to clean and prevent cloudy glasses in the future.

Identifying the Cause

The first step in restoring cloudy glasses is determining the cause. Gently rub a portion of the affected glass with a vinegar-soaked cloth. If the film lifts off, it’s likely due to hard water mineral deposits that can be removed. If the glass remains hazy, it may be etched, which is permanent damage to the surface of the glass.

Removing Hard Water Buildup

If your glasses are cloudy from hard water, follow these steps to remove the buildup:

Soak the glasses in white vinegar for 15 minutes, fully submerged.
Hand wash the glasses with warm, soapy water using a soft cloth or sponge.
Dry the glasses immediately with a microfiber cloth to prevent water spots.

Preventing Future Cloudiness

To help avoid cloudy glasses in the future, make these adjustments to your dishwashing routine:

Add a rinse aid to each cycle
Wash with water below 140°F
Avoid excessive pre-rinsing
Use less detergent with soft water
Regularly clean your dishwasher

While etched glasses can’t be fully repaired, you can improve their appearance by soaking them in vinegar or using a mild abrasive like toothpaste and baking soda. With some simple adjustments, you can keep your glassware sparkling clean and prevent future cloudiness.
