How do you fix a scratched mirror?

To remove scratches from a mirror, apply white toothpaste or polishing powder to a damp towel or rag and rub gently at the scratch until it is completely gone. If the scratches are too deep or are on the reverse of the mirror in the silvered surface, then a professional may need to handle the job.

Scratches on a mirror's surface that can easily be felt with a fingernail may not be able to be fixed. Light scratches can be buffed out with polishing compound.

1. Check the depth of the scratch
An easy way to test is to rub a fingernail across the glass surface, perpendicular to the scratch itself. If the scratch is easy to feel with a fingernail, then the scratch may not respond to treatment.
2. Clean with toothpaste
For very light scratches, white toothpaste may be able to buff out the scratch. Apply the paste directly to the scratch and rub it with a damp cloth. Clean away the toothpaste and check the scratch.
3. Apply polishing compound
Sprinkle jeweler's polishing compound, also known as cerium oxide, onto a damp paper towel or rag. Smooth the polishing compound over the scratch in small circles.
4. Check the scratch
Wipe the area with a damp towel or rag to check the progress. If the scratch is still present, repeat the polishing process. Continue checking and polishing until the scratch is completely removed from the mirror's surface.
