Evaluation of the effectiveness and the potential damage of cleaning methods for the restoration of stained glass windows

A comparative study on the effects of restorational cleaning methods for stained glass windows was carried out using corrosion sensitive model glasses. Typical deterioration phenomena like crusting, leaching and microcracking could be simulated using accelerated weathering in climatic test cabinets. The sensibilization of such samples caused by cleaning was assessed by infrared spectroscopy and light microscopy after re-weathering
