The effects of several cleaning solutions on samples of plasticized poly(vinyl chloride) were examined by several methods. The sample surface, prior to and after artificial photo-aging, was cleaned with several selected cleaning agents and examined physically (visual examination and under magnification) and chemically (attenuated total reflectance-Fourier transform infrared spectroscopy and gas chromatography-mass spectrometry). More than one type of effective cleaning solutions for the plasticized poly(vinyl chloride) used in the study was found. In addition, a specific method to tailor cleaning mixtures for plasticized poly(vinyl chloride) objects was developed by means of Hildebrand solubility parameters and the formulation of a Plasticizer Index calculated by quantitative measurements of the plasticizer obtained by attenuated total reflection Fourier transform infrared spectroscopy. Since this type of plastic material posed a standard cleaning challenge, the treatment described in this study can serve as a model or guideline for the investigation of additional cleaning methods for plasticized poly(vinyl chloride) objects.
