How to repair a damaged glass-top coffee table

Updated July 20, 2017

Glass-top tables are popular for their versatility in matching with many different furniture choices. The glass also offers easy cleaning with almost any type of cleaner. Glass will not end up with water stains if a glass is put on the table with protection underneath it. Repairing a glass-top coffee table that has been scratched is possible without replacing the entire glass. There are several products that can fix the scratches and save you money.

Clean the glass well with the cleaner of your choice and a soft cloth. You can use anything from soap and water to a brand name window cleaner. Dry the clean glass with a soft clean cloth.

Pour a small amount of lemon juice on a soft cloth and gently rub the scratch. Apply a small amount of pressure with the cloth while rubbing the scratch.

Apply a small amount of whitening toothpaste on the scratch and leave it on for five minutes. Wipe the toothpaste off with a soft wet cloth.

Apply clear fingernail polish to the scratch. This can cover superficial scratches on glass. If the preceding steps are not effective for your damaged glass, proceed to the next step.

Apply Jeweller's rouge to a lamb's wool polishing pad. Wear a dust face mask and goggles to protect yourself during the buffing process. Use the polishing pad on an electric buffer at medium speed directly on the scratches.

Mix one-half ounce of ammonia with two cups of warm water in a spray bottle. Put on rubber gloves in addition to the safety equipment you are already using. Spray the buffed area with the ammonia solution and then wipe with a paper towel.


Use extreme care when using ammonia. Never mix ammonia with bleach or any other household cleaner. Be careful when using the electric buffer that you don't apply too much pressure, because it can weaken the glass.
