Stir the frosting solution well with a wooden stick before use. Put the glass with a protective film on the back into the sanding rack (the angle of the glass is between 25°-30°), and the side of the glass that needs to be frosted is facing up. Pour the frosted sand liquid evenly on the glass surface from bottom to top for about 4-5 minutes (remember that the liquid needs to be poured on each part of the glass surface), and remove the frosted glass products for 10-30 seconds to recover the frosting liquid. After that, the glass surface can be completely washed with water.
