The removal of pesticide residues from museum objects is an ongoing concern. Historic information on pesticide residues and their detection, toxicity, and removal from artifacts have been the focus of numerous previous studies at the University of Arizona and elsewhere. This paper proposes four potential approaches for the removal of pesticide residues including cosolvent additives to supercritical carbon dioxide (SC-CO2), other supercritical gases, CO2 snow cleaning, and fluidized bed cleaning. The aim of this paper is to point out those research areas most likely to prove fruitful in developing and adapting these techniques so as to make them safe for use on ethnographic materials.
