Suan: I'll take the "easy half" of your question

I suspect you�re talking about Kleenox. It is a powder that you can sprinkle on your dross bed. Several points are: � Kleenox does not reduce dross. It reduces the amount of solder entrapped in dross. � Methods for reducing dross are: - Keep temperature LT 270�C - Run pump speed slower and only when soldering - Check solder contaminants to BS219, ASTM B32-66T - Use nitrogen tenting - Buy only low dross cast bar

One tiny warning on Kleenox, one chemical byproduct of the dross reduction process is fluorine gas. Not much of it, but enough to be irritating to the operators without breathing equipment or great ventilation.
