The modern city facilities are often being attacked by graffiti artists, and increasingly vandals leave "tags" using paints,
which compound based on acids, hydrofluoric or acetic commonly. These paints not only ink the surface, but also
increase the surface roughness, and such impact can not be corrected by conventional cleaning. Thus, it was requested to
develop technology that would not only clean the surface, but also to restore its structure by smoothing out irregularities
and roughness formed after exposure in acid. In this work we investigated the effect of restoring the surface of the glass,
spoiled by acid-based paint and then treated with CO2-laser. During the experiments, it was found that it is real to create
the single-step laser surface restoring technology.
