If you’re fact-checking “Here’s How to Remove White Patina from Glasses and Make Them Shine with a Cool Trick,” the white haze is often hard-water/mineral deposits, but sometimes it is permanent glass corrosion (etching) from repeated dishwasher exposure.
If it’s mineral buildup
You can try:
Soak the glasses in white vinegar for a short period.
Gently wipe with a soft sponge or cloth.
Rinse thoroughly and dry.
If needed, repeat rather than aggressively scrubbing.
The acidity of vinegar can dissolve many calcium-based mineral deposits.
But there’s an important catch
If the glass remains cloudy after the mineral deposits are removed, the surface may have been etched. Etching changes the glass itself and generally can’t be reversed with vinegar, baking soda, or ordinary dish soap. A glassware manufacturer or dishwasher-care guidance may recommend reducing detergent, avoiding excessive heat, and checking water hardness to prevent further damage.
Don’t mix vinegar with bleach or other cleaning chemicals.
Bottom line: The “cool trick” can work when the white coating is removable mineral residue, but it won’t restore glass that has been permanently etched.
