In most cases etched graffiti is created using a sharp implement creating damage over a large area, some of which are offensive words & gang tags.
Acid graffiti is a major problem in Britain, where vandals use acid in a shoe cleaning dispenser. This etches into the glass and forms a hard crust on the surface. Using our 'Graffiti-Away' process, the system removes and polishes out the etched surface with a minimum of distortion, leaving a smooth clear surface and renewing your glass back to its original look.
