Disclosed is a system and method for cleaning radioactively contaminated articles, including tools and like items of hardware. The system includes a cleaning chamber for receiving and sealing therein the contaminated articles, a high pressure spray gun disposed within the cleaning chamber for spraying the contaminated articles with a clean solvent to dislodge and dissolve the contaminants, and a system for decontaminating the solvent for reuse. The cleaning chamber includes a drain having the capacity to remove contaminated solvent at a rate at least as great as that at which the solvent is sprayed into the chamber, such that substantially no contaminated solvent collects in the cleaning chamber.
