How to sand and polish glass

Imperfections, protrusions and small cracks in the surface can be sanded on the glass. This process is most commonly used by mechanics cars to restore the cover of the headlights front with scratches. After sanding the glass, it will have a cloudy opaque appearance. The polish for glass will illuminate it and restore its transparent and shiny appearance.


  1. Wear safety goggles and gloves. Slight splashes of glass can fly during the sanding process, so you need to protect yourself.
  2. Fill a bowl with warm water and a dash of liquid dish soap. Dip a sanding block made with industrial diamonds or one that specifies its safe use on the glass with soapy water. The sanding block must have at least 600 grains. If you are not sure what grain to use, start with the lowest available grain and work slowly moving towards a higher grain.
  3. Rub the moistened sanding block in a back and forth motion on the glass. This will rough the glass. As you sand it, you will see it cloudy instead of transparent. If the glass still looks transparent or the scratch or imperfection that you are trying to remove is still present, select a sanding block with a higher grain. Continue to do so until you achieve the desired result. Dip the block into the soapy water when it begins to dry.
  4. Moisten a soft cloth with glass polish. Rub the product on the sanded glass so that the entire surface is covered with a thin, even layer. Allow the polish to dry on the glass, which should take about 15 minutes.
  5. Polish the polish by rubbing the glass with a dry cloth in circular motions. Continue polishing until all product is removed. If debris remains, moisten a cloth with running cold water and drain it to remove any excess moisture. Skip the waste. Repeat steps 4 and 5 until the glass is clear and glossy. This may take several tries.
