When it comes to those annoying, unattractive little scratches that appear on your glass goods, you can avoid the cost of professional repair or replacement and remove scratches from glass yourself. Household items made of glass, such as mirrors, windows, windscreens and coffee tables often become marked with scratches over time. Depending on the amount of damage, you may be able to restore your glass possessions to their former glory with little effort.

Step 1 - Assess the Damage

First, you will need to assess the amount of damage to decide the best course to take in successfully removing the scratches. To ascertain whether or not the scratch is too deep for you to repair yourself, try placing your fingernail into it. If this can be done, it will mean that the scratch is too deep and you will need obtain the help of a professional. 

Alternatively, if you can’t get your fingernail into the scratch, you will probably be able to tackle the job yourself. If the scratch covers a tiny area, such as that of an iPod screen or the face of a wristwatch, you can buff the scratch with a polishing pad by hand. The disadvantage of not using an electric buffer is that it takes much more energy to buff the scratch out and the results can be less impressive.

Step 2 - Get Buffing

Smear your polishing pad with the Jewelers’ Rouge. It is recommended that you use a lambs wool polishing pad, as it is incredibly gentle and provides an even pressure against the glass. If your Jeweler's Rouge comes in block form, you can apply it by holding it against the polishing pad while the buffer is running at a low speed. Any rough edges on the scratched glass can be flatted back using P1500 abrasive paper.

Put on your safety goggles and dust and buff the scratch using the electric buffer at medium speed. If you are not using an electric buffer, make circular movements with the polishing pad by hand against the direction of the scratch. Being gentle as you buff is important since the glass may be weakened by the scratch and a harsh amount of pressure could result in the glass shattering.

Step 3 - Cleaning the Buffed Area

Make sure you are wearing your gloves, goggles and a mask, as you will be handling a potentially dangerous chemical that you do not want to inhale or get on your hands. Be extremely careful not spill the solution anywhere. If it does get on your clothes, remove them imediately and wash your skin with water for 15 minutes.

Mix ½ oz. ammonia with 2 cups of warm water and pour into your spray bottle. Spray the buffed area with the ammonia/water solution and wipe clean with a lint-free cloth and paper towel. If the scratch is still obvious, you should repeat the previous stages. If the scratch is still visible after several attempts, you may need to approach a professional for assistance in either rebuffing or replacing the glass.
