- Choose the Right Grit: Pumice comes in different grit sizes. Start with a finer grit and progress to coarser grits if needed. Using too coarse a grit initially can cause more harm than good.
- Clean the Glass: Make sure the glass is clean before you begin. Remove any dust or debris.
- Wet the Surface: Wet the glass surface. This can help in the polishing process and prevent scratching.
- Apply Pumice Gently: Apply a small amount of wet pumice to the glass surface. Rub it in gentle, circular motions. It's important to be patient and not apply too much pressure.
- Check Progress: Periodically wipe away the pumice and check the progress. If the scratches or imperfections are still visible, you may need to repeat the process with a finer grit.
- Final Polish: After using pumice, you may want to follow up with a fine glass polish or a cerium oxide polish to achieve a high-gloss finish.
Remember, using abrasive materials on glass can be tricky, and it's easy to cause more harm than good if not done carefully. If you're not experienced with glass polishing or restoration, it might be a good idea to consult with a professional or use dedicated glass polishing compounds that are designed for the purpose. Always follow safety guidelines and use protective gear when working with abrasive materials.
