CHAPTER 5

Cleaning I: Application

This chapter provides an overview of the usage and properties of solvents, referring to their application as cleaning tools for surfaces of artistic and historical interest. Given a substance to be solubilized, the theoretical criteria for the optimal choice of the best solvent or solvent blend are illustrated, focusing in particular on the intermolecular interactions, quantitatively described by the solubility parameters fd, fp, fh (which indicate respectively the contribution to the intermolecular interactions due to London forces, polar interactions and hydrogen bonds).

The usage and the potentialities of the Teas charts are illustrated with particular attention to the free of charge application “Interactive triangle of solvents and solubility©” (available online) developed by the Istituto Superiore per la Conservazione ed il Restauro (ISCR) of Rome. Finally, some essential indications of the risks connected with the use of solvents, and their correct manipulation and storage, are presented.
