Things You'll Need
Polishing compound, jeweler's rouge or whitening toothpaste
Lamb's wool buffing pad
2 ounces of ammonia
2 quarts of water
Lint-free paper towels
Do not use abrasive household cream cleaners. Whitening toothpaste is a good alternative to polishing compound. If possible, lay the glass on a flat surface during the polishing process to provide additional support. If your fingernail can be inserted in the scratch, it is probably too deep to be buffed out.
Use gentle pressure to avoid breaking the glass. It is also important that you do not use a polishing compound that is overly abrasive or you could end up damaging the glass further.
How to Remove Scratches from Glass. Windows or other glass surfaces in the home can become scratched and unsightly over time. Instead of going to the expense of replacing the glass, it may be possible to buff out light or hairline scratches. Here are a few easy steps that might save you some time and money.
Apply polishing or jeweler's rouge to a lambs wool buffing pad. You can either buff the scratch by hand using a circular motion or with an electric buffer on medium speed.
Wash the polishing compound, jeweler's rouge or whitening toothpaste off from time to time in order to check on the progress of the scratch removal.
Mix two ounces of ammonia with two quarts of water. You may want to be sure to hold your nose closed during this process! Also, always wear rubber gloves and safety goggles when working with ammonia.
Clean the glass surface with the ammonia water with a clean soft sponge.
Dry the glass with a lint free towel. If the scratches are not completely gone, they should at least be less apparent. If there is no significant difference, consider contacting a glass company to replace or rebuff the glass.
