36 • smithsonian contributions to museum conservation FIGURE 1. Different cleaning mixtures were tested on a polychrome sculpture, labeled 1 to 7 on the photograph. All mixtures had the same solubility parameters, i.e., f d = 64, f p = 19, and f h = 17. The mixtures were as follows: 1, 50% acetone, 50% toluene; 2, 57% turpentine, 43% acetone; 3, 40% turpentine, 39% n-butylacetate, 21% acetone; 4, 51% acetone, 36% isooctane, 13% ethanol; 5, 53% 2-butanone, 29% nonane, 18% isopropyl alcohol; 6, 37% n-butyl acetate, 32% diethyl ketone, 31% turpentine; 7, 58% diethyl ketone, 42% dipentene. It can be seen that different mixtures with the same solubility parameter will not always be equally effective.
