How to remove scratches from car glass

Updated February 21, 2017

Car glass is subject to the impact of numerous materials, particles and atmospheric agents. These can cause scratches of various degrees to appear on the glass. Only light scratches can be eliminated or polished out. The larger ones would require glass replacement. Light scratches distort the reflection of light and thus reduce the driver's visibility. You don’t need to take your car to an auto shop to remove light scratches on your car glass; you can remove these scratches yourself.

Clean the car glass thoroughly. Use an alcohol-based cleanser or soapy water. Rinse the soapy water off and wipe the glass with a clean dry rag. Leave the glass to dry. Make sure that all residues on the glass have been wiped clean.

Add two tablespoons of glycerine and two tablespoons of cerium oxide to a small bowl. Cerium oxide is available in DIY stores and home improvement stores. Also add two tablespoons of water to the bowl. Start mixing the ingredients vigorously.

Put some of the mixture onto the scratched spot on the glass.

Take a rag or a paper towel and start gently rubbing the area. Move your hand in an up and down motion. Repeat this movement four to five times in the same direction. Change the direction of the movement and polish the area from side to side. Polish the spot in this direction four to five times.

Repeat Step 4 until the scratch is hardly visible.

Leave the compound on the scratched area to dry, but not for longer than 30 seconds. Rinse it off with mild soapy water. Take a dry rag and polish the area.

Inspect whether the scratch is still visible. Repeat the process a couple of times if needed.


If your fingernail catches in the scratch, the scratch is too deep to fix. You can use an electric buffer with a polishing pad to polish the scratched area.


Do not apply too much pressure on the glass, because it can break. Do not use an abrasive cleanser to polish the scratched area, because it can cause more damage to the glass.
