Avoid Damaging Your Etched Glass
Never use aggressive cleaning tools and materials like razor blades, or steel wool to clean your etched glass. It's also best to avoid using abrasive chemicals, too. Such materials and chemicals can cause permeant damage to the glass, which will greatly diminish its appearance. Anytime you clean etched glass, be sure to use plenty of water so you don't scratch or damage the surface. And never try to remove stains with a dry or dirty cloth; this could also cause scratches.
Since etched glass is a little more sensitive when it comes to cleaning, don't apply too much pressure as you clean. Too much polishing can cause damage to the acid-etched glass surface. So when cleaning, apply even, medium pressure. In addition, don't use products containing hydrofluoric acid, fluorine, chlorine, or ammonia derivatives. All of these products can damage the glass surface and leave permanent scarring.
Regular Cleaning
Although many people might assume that the only way to properly clean etched glass is by using a chemical-based product, the truth is much simpler. One of the best and most effective ways to clean acid-etched glass is with clean water and a soft sponge. Again, it sounds simple, and it is. However, if it will make you feel better, you can add a few drops of glass cleaner to the water. If you do so, always use standard glass cleaners that contain alcohol. You can also try a glass cleaner used and recommended by the professionals.
Just remember, when you do clean, always clean the full surface. If you only spot clean, it can create halos on the glass that will diminish the appearance. Once cleaned, the glass should be rinsed again with clean water and dried with a soft lint-free cotton cloth.
Removing Stains
If you notice that your glass is still stained after your initial cleaning, repeat the cleaning steps above. If the area is heavily stained, you can wash the surface using a low-pressure cleaning device with a water temperature of at least 86°F. The combination of low-pressure and warm water should effectively dislodge any stubborn stains and allow you to clean the remaining surface without damaging it.
Although distilled white vinegar is acidic (with a pH of around 2.5), when mixed with 2 parts baking soda the pH level can be increased to make it less acidic. If you're dealing with some stubborn hard water stains on your etched glass, try using a little distilled white vinegar mixed with baking soda to remove the stain. Cover the glass surface with the mixture, wait a few minutes, then use a soft cloth to gently remove the mixture. Once it has been removed, rinse the entire surface with clean, warm water.
Glass Cleaning Hack: Clean tough glass stains using toothpaste that contains baking soda. Apply the paste to the stained areas, rub gently, then rinse completely with warm water.
