The reason for suspecting lubricant is that I dont expect anything other than silver to be present. Since we know lubrication was involved that's the reasoning. As for the brewing, I get almost wax type stuff coming off the wire and makes the water opaque and dirty I am aware of the ion cloud but this is not that , after swapping the electrodes for the commercially bought silver electrode everything was as expected This really irked me since I was very new to brewing cs and assumed it was something I was doing wrong!
