How do you stop graffiti that is created by cleaning up the city in a very specific way? Apparently, you donâ€™t. Artist Paul Curtis, aka Moose, creates his works of art by cleaning dirt and grime off of city surfaces using only a shoe brush, water, and elbow grease (just like grandpa used to do). Being that he isnâ€™t really adding anything to the walls where he works, just cleaning them, British authorities arenâ€™t sure what to do to stop him, as they canâ€™t get him on charges of graffiti, typically done using paint. I like his idea, as the only way to remove the graffiti would be to clean the rest of the wall, thereby making the city he lives in a cleaner place. Graffiti with a purpose, now thereâ€™s something you donâ€™t see everyday.
