Anti-graffiti refers to measures and techniques used to prevent or remove graffiti from surfaces. This can include protective coatings that make it difficult for paint to adhere, as well as cleaning solutions designed to effectively remove graffiti without damaging the underlying surface. Cities often implement anti-graffiti programs to maintain public spaces and reduce vandalism. These programs may involve community engagement, where local residents are encouraged to report graffiti, and initiatives that promote public art as a positive alternative to vandalism.
