Polysciences, Inc., through a collaborative partnership with ProTech-Art LLC (formed by professors Richard Wolbers and Anthony Lagalante), has developed a series of Solvent Gels for cleaning fine art. Wolbers Solvent Gels™ are available in a convenient, ready to use kit and include six formulations that aid conservators in the cleaning of difficult or intractable fine art coatings. The gels range in polarity, from low (PolySolTM D60) to high (NMP). The standard kit consists of 100ml of the following solvent gels: PolySol™ D60, an aliphatic hydrocarbon similar to ShellSol™ D60 or Exxsol™ D60, Xylene, Benzyl Alcohol, Isopropanol, Acetone, and NMP (N-Methyl-2-pyrrolidone). Wolbers Solvent Gels™ are also available in single jars, mix and match kits, and bulk quantities.

In addition to solvents, the gels incorporate both a polymer and a surfactant. The polymer increases the viscosity of the solvent, which allows for control of the application (especially on vertical surfaces), spreading and penetration of the solvent into the art structure. The surfactant allows for a wide range of solvents to be gelled and also acts to solubilize and disperse soils that are not easily dissolved in solvent alone. The gels recently debuted at the American Institute of Conservation (AIC) Annual Meeting in San Francisco to an enthusiastic audience of art conservators.
