If smoke residue occurs on the piece of laminate during laser processing, clean it off using methylated spirits. Simply wipe it off with a cloth moistened with methylated spirits, then immediately wipe it with a clean, dry cloth. Nano sponges (often referred to as dirt erasers) can also be helpful when cleaning laminates. When cleaning glossy surfaces, carry out a test on a sample piece in order to determine whether the surface is affected by the methylated spirits (for example, whether it turns matte).
