10 Methods How to Remove Scratches from Safety Glass
1. Using Baking Soda Paste
A simple and cost-effective way to remove minor scratches from safety glass is by using a paste made of baking soda and water. Mix two parts baking soda with one part water to form a thick paste. Apply the paste to the scratched area with a microfiber cloth, using circular motions to buff the surface gently. The mild abrasiveness of baking soda helps polish out light scratches without damaging the glass.
Rinse the area with water and dry it with a clean cloth to reveal the improved surface.
2. Applying Toothpaste
Non-gel toothpaste is another common household item that can be used to remove scratches from safety glass. Apply a small amount of toothpaste to a damp microfiber cloth and rub it onto the scratched area in small, circular motions. The fine abrasive particles in toothpaste help to smooth out scratches. After a few minutes of polishing, wipe away the residue with a damp cloth and dry the surface. This method is particularly effective for superficial scratches.
3. Using Cerium Oxide
Cerium oxide is a specialized glass polishing compound that works well for deeper scratches. It’s often used in professional glass repair but is also available for home use. Mix cerium oxide powder with water to create a paste, and apply it to the scratched area with a felt polishing pad attached to a drill or by hand. The compound chemically reacts with the glass surface, filling in and smoothing out scratches.
Ensure the glass is cleaned thoroughly after application to remove any residue.
4. Buffing with a Glass Polishing Kit
Glass polishing kits, available at hardware stores, include all the necessary tools and compounds for scratch removal. These kits typically contain a polishing compound, pads, and instructions for use. Attach the polishing pad to a drill or use it manually to buff the scratched area.

5. Applying Metal Polish
Metal polish, such as brass or silver polish, can be used to remove minor scratches from safety glass. Apply a small amount of polish to a microfiber cloth and rub it onto the scratched area in circular motions. The polish fills in tiny imperfections, making scratches less noticeable. Wipe away any excess polish with a clean cloth and inspect the surface for improvements.
This method is ideal for addressing light to moderate scratches.
6. Using a Commercial Glass Scratch Remover
Commercial glass scratch removers are specially formulated products designed to repair scratches on glass surfaces. Follow the manufacturer’s instructions for application, which usually involves applying the solution to the scratched area and buffing it with a polishing pad. These products often contain abrasives or chemical agents that target scratches effectively. They are widely available and provide a reliable solution for various scratch depths.
7. Sandpaper and Polishing Compound
For deeper scratches, a combination of fine-grit sandpaper and polishing compound can be used. Start with wet/dry sandpaper (800-1000 grit) and gently sand the scratched area, keeping the surface wet to prevent further damage. Once the scratch is less visible, switch to a finer grit (2000-3000) for additional smoothing. Finish the process by applying a polishing compound to restore the glass’s clarity.
