Laserclean machines are 100% safe for your rollers. Unfortunately, some laser equipment manufacturers have sold machines which can result in damage of the roller surface. The newest generation Laserclean machines made laser cleaning faster, easier, more effective and 100% safe for the surfaces being cleaned. The energy provided by the laser beam is strong enough to vaporate the dirt but too weak to damage the roller surface. Even smallest cells are deeply and completely cleaned. Guaranteed.
