How sanding and polishing glass

Imperfections, bumps and small cracks in the surface can be sanded in the glass. This process is most commonly used by mechanics of cars to restore the cover of the headlamps front with scratches. After sanding glass, it has an opaque cloudy appearance. Polishing glass restores its clear and bright appearance.


  1. Use protective goggles and gloves. Light splash of glass can fly during the sanding process, so you need to protect yourself.
  2. Fill a bowl with warm water and a squirt of liquid soap dishes. Dip a sanding block made of industrial diamonds or one that specify their safe use in the glass with soapy water. The sanding block must have at least 600 grains. If you’re not sure what grain to use, begin with the lowest grain available and work slowly toward a higher point.
  3. Rub the wet sanding block and move back and forth on the glass. As you know, you will see  a cloudy glass instead of a clear one. Even if the glass is transparent or scratch or blemish and what you’re trying to delete is still present, select a sanding block with a higher grain. Continue doing so until you achieve the desired result. Dip Block in soapy water when it starts to dry.
  4. Dampen a soft cloth to polish glass. Rub the product on sanded glass so that the entire surface is covered with a thin layer. Let the polish dry on glass, which should take about 15 minutes.
  5. Polish rubbing the glass with a dry cloth in a circular motion. Polishing continues until the entire product is removed. If residue remains, moisten a cloth with cold running water and drain it to remove any excess moisture. Repeat steps 4 and 5 until the glass is transparent and glossy. This may take several attempts.
