Tried it, liked it a little.  Stoped using it when we could found it 
cound not be used on peroxide containing lines.  The peroxide has a 
higher chemical voltage than the electrical power supply voltage, and 
will etch the copper off of the electrowinnowing cathodes.  Works best 
on batch treatments of known composition, such as drag outs tanks, or 
spent baths.

Have fun.

I work for Raytheon E-Systems Falls Church. They disclaim anything I say 
here since it is my own personel opinion.
