The matte painted surface is softer than the general coating, and scratches and stains on the painted suurface are easy to stain, so please be careful about handling. As wiping off the dirt and stains on the matte painted surface, please use a soft cloth soaked with water-diluted neutral detergent and be careful not to rub the surface hard. It may cause the matte paint to be lost and the gloss may come out. In addition, please do not use compounds (abrasives), plastic cleaners, wax and other chemical products and solvents such as benzene, thinner or gasoline which may cause stains or gloss on the matte painted surface.
