What materials are used for polishing glass?

Polishing glass uses polishing liquid or polishing powder. The main component of polishing materials is cerium oxide, with polishing powder being cerium oxide polishing powder, and polishing liquid being a water-soluble polishing agent free from sulfur, phosphorus, or chlorine additives. Both materials have moderate hardness, enabling fine polishing of glass with excellent results. Polishing can remove surface patterns, scratches, and other imperfections from glass, improving its transparency and refractive index, thereby restoring the glass to its original clarity. Before polishing, it is necessary to clean the glass surface of impurities to avoid secondary damage during polishing. Then, apply the polishing liquid to the polishing machine, ensuring uniform polishing force and appropriate pressure, with slow grinding to guarantee the desired effect.
Materials for polishing car glass, which I've personally tried several times, commonly include cerium oxide polishing paste, a white powdery substance. When used with an electric polisher and a soft pad, it can gently remove scratches. There's also aluminum oxide compound, suitable for minor imperfections. The key is to avoid using regular car wax or abrasive compounds, as those can scratch the glass deeper. I recommend testing a small area first to ensure the material won't damage the coating or affect visibility. Additionally, after polishing, the glass becomes clearer, significantly improving visibility while driving. However, don't do it too frequently, as over-polishing can thin the glass and compromise safety. Remember to wear gloves and goggles, ensure good ventilation when handling the materials, and avoid inhaling the powder. Although professional tools are expensive, investing in them once saves a lot of hassle.
For DIY glass polishing, selecting the right materials is crucial. For instance, cerium oxide polishing compound works well when applied to a microfiber cloth or polishing pad, and can be used with slow hand polishing. Aluminum oxide powder is a more economical option, ideal for minor scratch removal. I typically mix it with water or a specialized lubricant to prevent glass from overheating and cracking. Another key point: material selection depends on the glass type—use gentler products for laminated glass to avoid damaging the plastic interlayer. In terms of tools, a drill with a polishing attachment is essential, ensuring gentle and even pressure during operation. Post-polishing residue cleanup is critical to avoid leaving marks. A handy tip: glass polishes more easily after rain, as moisture aids the process. DIY saves hundreds, but avoid cheap knockoffs—I learned the hard way that they deliver poor results.
