ABSTRACT:
Graffiti removers particularly useful for removing permanent ink from painted surfaces are disclosed. The graffiti removers include a dye solvent (a pyrrolidone or a lactone), a dye non-solvent (a glycol ether ester or a glycol diether), and a dye bleaching agent (an oxidizing agent, reducing agent, or base). The dye bleaching agent is the key to eliminating the problem of "ghosting" that is observed when conventional graffiti removers are used to remove permanent marker ink graffiti.
