I have a large mirror on my wall that needs to be removed. Is there a
safe way to remove it so it does not break?
Try using windshield removal wire. Start at one corner and work it down
the length of the mirror between the adhesive and the wall. If you want
to save the mirror be careful not to damage the silver on the mirror's
back. Because the mirror was glued on there will most likely be some drywall
repairs to do.
