Graffiti is generally considered a form of vandalism. The painted pictures and messages create a lot of work to either paint over or scrub off. But what if the street artist doesn’t use paint, or put any sort of substance on the walls (or whatever surface) to create his design? What if he is cleaning dirt off the walls?
Reverse graffiti is a fairly new form of street art. It is used not just as an avenue of personal expression but also for commercial advertising. Authorities often don’t like it, because the art and advertising are “unauthorized.” But there are generally no laws against cleaning dirt off public spaces, so there’s not much they can do about it. Except finish the cleaning job that the artist started.
Take a look at some of these works of reverse graffiti. I was especially impressed by what Scott Wade can do with a dirty car window.
