Cover Story: Graffiti presents significant challenges to the visual appeal and environmental well-being of urban infrastructure and cultural heritage sites, underscoring the need for improved removal techniques. Conventional solvents commonly employed for this purpose are often toxic and frequently ineffective in dissolving graffiti paint. In this study, the potential of the bio-renewable solvent Cyrene™ was investigated for the first time in the context of paint removal. Cyrene proved to be an exceptional solvent for graffiti paint removal, offering not only safety and sustainability but also remarkable efficacy. Additionally, a Cyrene-water solvent system unlike NMP-water and DMF-water was also very efficient in removing paint. View this paper
