Some idiot "tagged" the side of my house with graffiti. Neon yellow spray paint on brick. About a 3' x 5' section.
I thought I'd have to get a pressure washer, but decided to give the ole Goof Off a try, since graffiti removal is supposed to be one of its "real" uses.
It took it all off in about 20 minutes with some scrubbing.
There's still a few tiny spots of paint in some cracks, but it did a surprisingly good job. Hopefully it won't happen again, but I live on a corner in the heart of a big city, so I'll probably end up breaking out the Goof Off again.
