Hyunbin,

I would never use an aqueous solution to clean a vacuum system. Acetone or denatured alcohol are what I would prefer. The water adheres to the chamber walls and is hard to remove. I sugest that you pump down your system and "outgas" it by heating as much as possible to drive the water vapor off the walls of the chamber.

In addition, your system seems to be unable to remove this contamination in a reasonable time which seems to indicate a leak or an inadequate pumping system.
