ABSTRACT:
In order to quickly and inexpensively rinse recyclable acid bottles which contain acid residues or decontaminate pieces of apparatus which are contaminated with acid, the interior of the bottles or apparatus is rinsed with an alkaline solution and then with water. The exterior of the bottles or apparatus is rinsed with water. The alkaline solution is stored in fiberglass canisters and is displaced to spray nozzles by the application of air under pressure. Valves which control the supply of water and alkaline solution are controlled by either solenoids or by air-activated devices. In the case of air-activated valves the air under pressure which is used to force the alkaline solution toward the spray nozzles can be used to operate the valves.
