How to clean cloudy vintage glass and decanters

Step by step

1. 1

   Step 1: Test the cloudiness

   Wet the cloudy area or wipe a little mineral oil on it. If it clears while wet and comes back when dry, it's probably etching, which is permanent.

2. 2

   Step 2: Soak off mineral film

   For hard water film, soak the glass in warm white vinegar for a few hours, then wash in soapy water.

   Step 3: Decanters and vases

   Drop in two denture tablets with warm water and leave overnight. For stubborn rings, add a handful of rice with some vinegar and swirl so the rice scrubs the inside.

   Step 4: Dry properly

   Rinse with hot water and dry upside down on a rack so air can get in. A rolled up paper towel inside a decanter soaks up the last drops.

   Step 5: Be honest about etching

   Etched or sick glass can only be fixed by professional polishing. Don't oil it to hide it when selling. Describe it as cloudy in your listing.
