Method for Cleaning Metals, Oils, and Solvents from Contaminated Wipers, Cloths, Towels, and the Same

Abstract

Method for cleaning metals and organic solvents adsorbed to tissues. Soiled tissues are placed into a container or specially designed collection and cleaning container. An aqueous reagent formulation solution, not to exceed 15% of reagent in water on mass-mass basis is prepared. The required concentration of reagent as a function of the type and level of contamination of the tissues and the contaminants of concern to be cleaned is determined. The reagent solution of desired concentration to the soiled tissues in the container is then added. The dissolved reagent and soiled tissues are mechanically mixed to create intimate contact at ambient or above ambient temperatures. The container is sealed allowing the cleaning to occur for a period of time. Testing for metals and organics solvents are performed to confirm that the metals are stabilized/immobilized and the volatile organics are degraded. The tissues are then dried for reuse, recycling, or disposal.
