Is this your challenge ?
In one step, this method cleans, passivates and polishes metal surfaces electrochemically. Polishing drastically reduces the incrustation of subsequent contamination, an added bonus of this specific method. The switchable AC/DC devices also facilitate direct current (DC) mode for high-gloss polishing.

The newly developed carbon fibre brush (up to 2 million fibres are used per brush) are conducting high current to the work piece (current density up to 250 A/cm²). To maximise the cleaning, the fibres of the carbon fibre brush hug the shape of the work piece ; different brush types make any cleaning task easier and there are in-pipe brushes to allow for pipes and holes to be cleaned from the inside.
