Never try to remove impurities with a dry and/or dirty cloth, as this may cause scratches on the glass surface by rubbing impurities on the glass.
How do you remove hard water etching from glass?
You can remove the buildup caused by calcium and magnesium ions in hard water by swabbing the glass with acetone (nail polish remover), and then scrub gently with a mild detergent. Soaking the glasses in plain white distilled vinegar for 15 minutes is another effective home remedy.
Can hard water stains be permanent?
Hard water stains should be removed regularly. The longer a stain is allowed to sit, the harder it will be to remove. If a stain remains for long periods it can become permanent.
