Tips for Polishing Pads
- Clean pads frequently during use with compressed air, a vacuum, or an SPTA pad conditioning brush tool to maintain consistent performance.
- Do not over-saturate the pad with compound. Too much compound can lead to diminished performance.
- Clean with warm water and a mild soap after finishing work, rinse totally to remove residues. Air dry to avoid solvent-based compound and cleaner remains and protect the foam's cell structure.
