1. Gradual Polishing

   Adopt a gradient polishing process: start with a low-grit pad (50 or 100 grit) to remove deep scratches, then switch to a 3000-grit pad for the final polishing stage.

2. Use a Backing Pad

   First attach the polishing pad to a backing pad, then secure the assembled backing pad and polishing pad to the polishing machine.

3. Proper Technique

   Do not exceed the maximum speed range of 4,000–4,500 RPM. Use slow, overlapping movements during operation to prevent the pad from getting stuck.

4. Clean the Surface

   After changing polishing pads between grit stages, clean the work surface thoroughly to remove any leftover abrasive particles.
