Abstract:
In order to protect and conserve in time the cultural and artistic heritage there is the
need of complex preservation, restoration, and exhibition activities. This article presents
modern procedures of cleaning the adherent coating from old patrimony paintings. There is a
multitude of factors that contribute to deterioration. The protection and conservation in time of
the cultural and artistic patrimony impose a series of preliminary consolidation measures
followed by cleaning. Irrespective of the procedures: classical, modern, or by laser pyrolysis,
the cleaning has to be stopped when original colour layers appear. The preservation and
restoration of paintings in general, are connected to very complex operations made by
specialists in this field.
