Claim:
1. A method of etching comprising: providing a tank of an electrolyte; providing an electrode system including a cathode present within the tank of the electrolyte and an anode that can be traversed from a first position within the tank containing the electrolyte to a second position in which the anode is removed from the tank, wherein the anode is mounted to a holder; traversing the anode and a portion of said holder into the first position and applying a bias to the cathode and the anode to etch the anode; traversing the anode and said holder into the second position and rinsing the anode with a fluid jet to dilute a remaining portion of electrolyte present on the anode; and removing at least a portion of remaining fluid from the fluid jet and electrolyte that has been diluted from the anode while in the second position with a dryer to blow the portion of the remaining fluid and the electrolyte that has been diluted from the anode into the tank, wherein a liquid including drag out electrolyte is present on the anode in an amount ranging from about 5 ml to about 50 ml.
