Can Car Glass Scratches Be Repaired by Polishing?

[DelDelilah]

Minor scratches can be polished. Polishing is only effective for shallow scratches. For large-area or deep damage, manual grinding usually cannot achieve precise results, and in such cases, it is recommended to replace the glass. Polishing techniques are categorized as follows: 1. Mechanical Polishing: This method involves removing the raised portions of the scratched surface through cutting and plastic deformation to achieve a smooth finish. 2. Chemical Polishing: Chemical polishing allows the microscopic raised areas of the material to dissolve preferentially in a chemical medium, resulting in a smooth surface. 3. Electrolytic Polishing: The basic principle of electrolytic polishing is similar to chemical polishing, where selective dissolution of microscopic raised areas on the material's surface creates smoothness. Compared to chemical polishing, it eliminates the effects of cathode reactions and yields better results.
