Economics of Dust.

The article examines the economic implications of cleaning in response to the flow of visitors through historic houses. The section reflects on work carried out in properties of the National Trust for England, Wales, and Northern Ireland, which is the largest accredited museum authority in the U.K., with 175 furnished properties open to visitors for seven months each year, on average five days per week and four to five hours a day. According to the study, although it describes how control of dust influences property management and housekeeping policies in the National Trust, the outcomes are applicable to historic properties in general and to museums and galleries where significant interiors and collections are exposed to dust.
