Clean the glass:
For any scratch treatment to work, it is important that the glass surface is clean. Use a good quality glass cleaner spray and wipe it off with a clean soft cloth. Concentrate on the scratch area during the process.
Toothpaste is widely used to treat the scratches on mirrors. Regular tooth paste used commonly in homes can help you get rid of minor scratches effectively. Take out some paste on a cotton swab. Now polish the scratched area with this swab in a circular motion. Leave the toothpaste on the mirror for up to four hours so that it dries there. Use a soft cloth to wipe off the dried toothpaste from the mirror. You will notice that it has made a great difference.
Vinegar and mustard:
This solution can also be used for eliminating scratches. It can be made at home and is very effective. Mix one part white vinegar and one part dry mustard. Now use a crafts brush to apply this mixture to the scratch area like the toothpaste above. The mixture should be enough to cover all the scratches on the mirror and fill them. Let the mixture dry on the mirror for an hour. Now wipe it off with a soft cloth. You will get rid of most of the scratches in the first attempt. Repeat for better results.
