Abstract

The need for removing graffiti, as it would be expected, brought a whole range of products under the moniker graffiti removers from suppliers of conservation materials. The fact that often the graffitied surfaces are ancient marbles or sometimes parts of fortification walls contribute to additional complication to the entire issue because of the often poor condition of the surface of the monuments and the difficult accessibility.

We faced the need for identifying the chemical substances existing in various graffiti removers, which are typically supplied by several conservation material vendors and for testing their effectiveness on the various types of colored spray paints on variable types of surfaces with infrared spectroscopy.

Five different products were tested on different types of surfaces and colors, and their effectiveness on removing the graffiti was documented. Mock-up samples were constructed of marble. They were accordingly spray-painted with the most usual colors encountered in graffiti (black, blue, red, and yellow), which were also analyzed through FTIR. The surfaces were then cleaned with five different graffiti-removing products. The effectiveness of cleaning was visually evaluated and then colorimetry-measured to assess the effectiveness of each remover. The effectiveness of the investigated commercial products was generally summarized.
