“…This study was motivated by the observation, over the last fifteen years, of a demonstrable increase in difficulties regarding the surface cleaning of emulsion paint layers, whatever the techniques used; investigations into the cleaning of paint layers [1][2][3][4][5] led to further understanding of some of these phenomena, involving the irreversibility of certain types of soiling on acrylic paint layers.…”

This article attempts to highlight a phenomenon that more or less permanently damages emulsion paint layers, the surfaces of which remain sufficiently permeable for dust particles to become permanently anchored there; when the particles are nanometric, this can cause a permanent change in appearance. Based on scientific documents, empirical observations, laboratory analyses, case studies, and reconstructions of characteristic pictorial layers, this paper aims to highlight the medium- and long-term risks that alter these surfaces, in order to realize strategies for better prevention. The physico-chemical nature of these vulnerable materials will be discussed first, followed by the dust’s involvement; finally, the topic will be illustrated through concrete examples, with photos taken using digital, 4 K optical, and Scanning Electron Microscope equipment (SEM), in order to show how the problem of dust particle accumulation impacts even the most contemporary works of art.
