Things You'll Need
Plastic butter knife or similar dull and rigid item
Glass cleaner or white vinegar (optional)
Candles are often used in homes to scent the air, and to decorate rooms. Candles are often attached to mirrored sconces or set upon mirrored bases, because mirrors increase the illumination. Wax that has splashed or dripped onto a mirror can be removed with a couple of household items.

Place the mirror in the freezer, if it is small enough. Leave the mirror in the freezer for at least 45 minutes. If the mirror is wall-mounted, or too large to fit into the freezer, rub an ice cube or baggie full of ice over the wax drippings for several minutes. Freezing temperatures cause the wax to shrink and become extremely brittle.
Use a plastic butter knife or similar item to pull up the hardened wax. Work the edge of the knife under the edge of the wax; pry it up. The wax will pop off with very little force.
Allow the mirror to come back to room temperature for an hour or so. You will be heating the mirror, which may crack the mirror if it is still cold.
Use a hair dryer to liquefy the wax. Use a paper towel to immediately wipe off the liquid wax. If a film remains on the mirror, clean with glass cleaner or white vinegar.
