Hi all - Can anyone recommend a good way to remove a glob of concrete or mastic off the back of a hand=painted memorial tile? We have a collection of tiles that were removed from a wall and about a quarter of them came away with a combination of backer board, mastic and/or concrete. We've done some chipping, but we're afraid of breaking the tile as a whole if we keep on with that process.
