Things You'll Need
Toothpaste (not gel)
Small paint brush
Discovering that someone has damaged your property can be distressing, but if vandals have etched graffiti into a mirror, you might be worried that the damage is permanent. Small scratches can be removed without specialist help. You can try to get rid of the scratches using two methods that involve common household items. However, if you are not able to remove the scratches yourself, you might have to consider getting the mirror resilvered.
Clean the affected area of glass using glass cleaner. Spray a small amount of cleaner on the glass and wipe it off using a small cloth.
Squeeze a small amount of toothpaste onto a cotton swab. Apply the toothpaste to the scratch in a circular motion, ensuring you cover the whole scratch. Leave the paste to dry. After four hours, it should have formed a crust over the mirror, though you may have to leave it longer depending on how much you applied.
Take a soft cloth and gently wipe the toothpaste off. Do not use glass cleaner at this stage; the dried toothpaste should wipe off on its own.
Clean the mirror surface if necessary and ensure it is dry. Mix equal amounts of vinegar and dry mustard together into a smooth consistency.
Apply the mixture to the scratch using a small paintbrush. Make sure you cover the entire scratch thoroughly.
Leave the mixture on the mirror for an hour, then wipe off with a soft cloth. Do not use glass cleaner; the mixture should lift off the mirror with repeated rubbing.
