Evaluation tests of the water rinsing on the contaminated superconducting cavities were conducted with high pressure water rinsing (HPR) and megasonic rinsing (MSR). It made sure HPR eliminates very effectively the surface contamination. MSR is just started, but the preliminary result seems that it is useful to reduce the field emission over than Eacc = 25 MY 1m. The quality of rinsing water was also investigated. Filtered pure water looks to be usable instead of ultrapure water.
