what kind of contamination are you dealing with? ultrasonic bath with IPA should do the work, if not, you can always try trichloroethylene (this is last option, its very hazardous)

Contamination color is silver dust, like ash dust from burning wood. The pressure of nitrogen is 27 and the flow is 0.3. Do you know where can i find some documentation about nitrogen and fluxing?

I would email Chad at ERSA and see what he might have to say, relating to your Versaflow. he's always been a big help to me.

yep, thats it. you will need to clean the whole pot. I used some dishwashing wire and Kyzen, and then removed Kyzen residues with IPA.

The main problem is that we changed the whole pot 1 year ago. From where does this containment comes from?
