Wax stain on paper artwork is one of the most chronic and complicated problems during conservation treatments. Understanding changes to the marbled paper samples during cleaning with gel-based microemulsion is one of the most important issues for conservators of painted works on paper. This research aims to evaluate the effectiveness of Texapon N70 confined in PVA/ gel for removing wax stains on marbled paper and stopping wax penetration into the paper structure. Characterization procedures before and after cleaning were performed using a digital microscope, SEM microscope for morphological study, and FTIR spectroscopy to detect the chemical structure change. The roughness of the samples was measured using an atomic force microscope (AFM). The results of the test demonstrated that the substance could be safe and more effective for removing wax stains from marbled paper. The used gel-based Texapon microemulsion was capable of removing the wax stain from marbled paper, and the results of the test demonstrated this material's ability to safely and effectively remove wax stains from marbled paper.
