Cleaning the Sargent murals: Introduction

A critical component of the 2003 restoration is the cleaning of the murals. Conservators strive to understand many of the issues relating to a work of art before starting a cleaning treatment, since misguided efforts can lead to damage. Issues include the artist’s materials and techniques, his aesthetic intent, the nature of the grime to be removed, environmental conditions, and the effects of past restorations. Conservators also use visual examinations, scientific analyses, and reviews of archival records to develop treatment methods.
