How to Polish Glass With Cerium Oxide

Kristian Welsh

Glass is a material used in windows, tables and numerous other household items. Glass scratches quite easily. A single scratch can detract from the overall appearance of a glass surface. Scratches that are not too deep can easily be buffed out using cerium oxide.

Scratched glass windows are unsightly.

Scratches that are too deep will be impossible to polish out, and the glass will have to be replaced.

  1. Apply cerium oxide to the electric buffer's polishing pad. A small amount will work for most scratches.

  2. Set the electric buffer to "Medium." Lightly buff out the scratch. Be careful not to crack the glass. Scratches weaken the integrity of the glass, making it easier to crack. Wear goggles to protect your eyes while buffing.

  3. Pour 1/4 oz. ammonia with 1 cup of water into the spray bottle. Wear gloves while handling to be safe. Shake it gently to mix the two ingredients.

  4. Spray the area you have buffed with the ammonia/water mixture.

  5. Use the lint-free towel to dry the area.

  6. Repeat Step 1 through Step 5 if the scratch is still visible.
