Brookline Graffiti delivers what it promises: Photos of graffiti - and the anonymous blogger's war on it:

As you can see, the razor just scraped away what would have been many layers of scrubbing! Usually you have to alternate a layer of scrub with a layer of scraping, as the solvent penetrates on each pass. But in some cases, like on this mailbox, I got almost all of it off on the first scrape.

Whenever I have a smooth surface, I always have my long razor handy. It saves a lot of time, and sometimes, is the only way you’ll get some paints off the surface.
