To remove shallow scratches from glass, apply a commercial solution, such as metal or nail polish, or create a home remedy with toothpaste and baking soda. For deeper scratches, buff out the damage with cerium oxide and a polishing wheel attached to a drill or dremel tool.
These methods do not actually remove the scratches, but instead fill them with substances that resemble glass so the scratches aren't visible.
Step 1: Apply a commercial solution
Nail polish and metal polish are two common remedies for lightly scratched glass. Apply just enough to fill the scratches, then buff with a soft microfiber cloth. Avoid using paper towels or abrasive sponges, as these can deepen existing cracks or make new ones.
Step 2: Make a homemade solution
In the absence of a commercial polishing solution, mix toothpaste with baking soda, then rub it into the cracks. Wash it completely clean afterward, then repeat as necessary.
Step 3: Buff out the scratches
Cerium oxide is a polishing substance that fills deeper scratches. Mix it with a small amount of water to create a thick liquid, then apply it to the scratches in the glass with a cloth. Maintaining a moist work surface, buff the area with a polishing wheel attached to a drill until the glass surface is smooth again.
