Cleaning wipes in an office is a typical good thing to have. A customer comes to visit and needs to clean the screen of his smartphone, glasses or something else, having cleaning napkins immediately shows a good side. Use: First, remove hard dirt such as sand or crumbs from the surface to avoid scratches. Take out and open a bag with a cleaning cloth from the package. Clean the dirty area until the surface is clean. The cleaning liquid evaporates and leaves a dry surface.
