Getting rid of those unsightly stains on your favorite glass pieces can be tough, especially if the stain is old and the glass piece is fragile. Although most glass pieces can be taken to a specialist for repair, there are ways you can remove the stain yourself.
Removing the Stains
Using a container large enough to put the glass object in, fill the container with cold water until the glass object is submerged. Drop in two denture tablets and allow them to dissolve. Leave the glass object in the container overnight, and the next day use a hard-bristled toothbrush to scrub the stain away.2
Put your glass object in a container big enough to hold it completely and fill the container with white vinegar. White vinegar contains acetic acid, and can be used to remove glass stains. Let the glass object soak overnight in the white vinegar, and scrub the stain using a hard-bristled toothbrush.3
Put on a pair of rubber gloves. Take a cleaning cloth and pour a quarter-size amount of CLR onto the cloth. CLR (calcium lime rust) is a cleaning product that helps remove stains from glass and other surfaces. Rub the stain with the cloth, and then scrub the stain with a scrubbing pad. Once the stain is removed, use the clean part of the cloth to remove excess CLR liquid.4
Take a sheet of newspaper and wipe it over water-stained glass to remove excess dirt. Take another sheet of newspaper, wet it with water, and glide it over the glass to remove water stains. Once the glass is wiped clean, take a lint-free cloth and wipe the glass.5
Use a dime-sized amount of rubbing alcohol on a cleaning cloth and rub cosmetic stains. Once the stain is removed, use the dry part of the cleaning cloth to wipe it clean.6
Take your glass piece to a repair specialist. If you have tried to remove the stain yourself with no luck or worried about damaging the glass, a glass professional can attempt to remove the stain for you. You can search online or the Yellow Pages to find a glass specialist in your area.
