    Abstract: In a method for cleaning for cleaning metallic ion contamination, and especially copper, from wafer containers, the containers are loaded into a cleaning apparatus. The containers are sprayed with a dilute chelating agent solution. The chelating agent solution removes metallic contamination from the containers. The containers are then rinsed with a rinsing liquid, such as deionized water and a surfactant. The containers are then dried, preferably by applying heat and/or hot air movement.

    Abstract: In a method for cleaning for cleaning metallic ion contamination, and especially copper, from wafer containers, the containers are loaded into a loader of a cleaning apparatus. The containers are sprayed with a dilute chelating agent solution, while the rotor is spinning. The chelating agent solution removes metallic contamination from the containers. The containers are then sprayed with a rinsing liquid, such as deionized water and a surfactant while the rotor is spinning and heat is applied. The containers are then dried by applying heat, hot air movement and spinning the rotor.
