For these glasses it is necessary to use the polishing, since the polishing of glass loses the thickness of only fractions of a micron, while small scratches are removed and the glass becomes more transparent. You can use the paste with the grain to 0.5 microns – the smallest, but the best effect is achieved with the paste Polyarit". For very small scratches used diamond paste (lapping), it will also help in removing permanent stains.

To remove scratches with a thicker glass, especially if there are a lot of small or large scratches, use polishing, but then necessarily it is necessary to Polish the surface. For manual polishing using emery paper # 200-800, medium - to coarse paste (diamond and boron, intermediate and grinding). The more you scratch, the bigger grains need to apply in the first stage, the second less, the third even less and so on. This process is very long and time consuming. With the help of special machines, of course, it will go faster. But if you don't want to completely ruin the glass, then you need to practice on other glass that is not a pity to determine with what degree of pressure need to be sanded.
