Guard Dog II  (1969–1970) by Jean Dubuffet is an artwork that shows the characteristics of the artist's l'hourloupe period (1962–1974). This study revealed the materials and manufacturing techniques used by the artist at the time through material analysis of  Guard Dog II , and suggested an appropriate conservation treatment method for the work through a cleaning test. Dust, stains, discoloration, cracks, etc. were observed on the surface of the artwork and stains were particularly severe and discoloration required conservation treatment. Prior to treatment, multiple analytical approaches such as Fourier transform infrared spectroscopy, Raman spectroscopy and gas chromatography/mass spectrometer were applied to identify the materials of the paint layers and confirm the state of the conservation of the artworks. As a result, it was confirmed that polyurethane paint was used in the artwork, and the pigment used for each color was also identified. For the stable conservation treatment of the artwork, the chromaticity, glossiness and workability of the cleaning materials were evaluated, and it was found that isopropyl alcohol and nonionic surfactant were suitable for cleaning. The conservation treatment was performed based on results from the cleaning test, and the artwork was restored cleanly. Since most of the existing research on cleaning methods has been focused on painting, this study contributes to the conservation of sculptures by suggesting cleaning methods suitable for three-dimensional colored objects. Article highlights The materials and production techniques used in Jean Dubuffet, Guard Dog II were confirmed. As cleaning materials for deteriorated artworks, isopropyl alcohol and non-ionic surfactants are effective. Hydrogels are not suitable for this work due to the type and characteristics of the gels.
