We have constructed an Electro-polishing (EP) Facility in the Superconducting RF Test Facility (STF) at KEK at the end of 2007. We have been operating the EP facility since January 2008 and have performed the EP- processes of cavities about 200 times up to the present. We changed EP-electrolyte in the 2,000L tank three times until now. And we use the 4th-period EP-electrolyte now. We presented the long-term monitoring result of the 2nd-period EP-electrolyte so far. In this report, we present the long-term monitoring results of the 3rd-period EP-electrolyte, the correlation between EP-process data and the change of fluorine chemical species by EP-electrolyte aging, the result that we could achieve good performance by the EP-electrolyte old enough. And we want to suggest the new EP chemical equation.
