Abstract
Clean room wipe products, methods of preparing them, and methods of using them are described. The clean room wipes are intended for use in cleaning up alkaline contaminants in clean room environments. The wipes contain impregnated acidic solutions, e.g., solutions of organic acids and optionally solvents, which are intended to reduce or eliminate the possibility of spontaneous combustion of the contaminated wipes, that is, when the wipes are used to contain spills of alkaline products such as hydroxylamine-based products and other caustic based formulations.
