Can I use a sandblasting machine to remove graffiti?

No, you can't use a sandblasting machine to remove graffiti. Sandblasting is the process of using abrasive materials such as glass beads or steel shot to blast away paint and other coatings from surfaces. Graffiti is usually painted directly onto walls and other surfaces. So you can't use a sandblasting machine to remove graffiti.
