A clean stainless steel surface will generate its own passive oxide layer when exposed to oxygen. It is this oxide layer that gives stainless steels their corrosion resistant qualities, it is possible however to accelerate the formation of this layer by chemical passivation.

Electropolishing is in effect electroplating in reverse. Instead of depositing a coating of another material on a surface the process of electropolishing is to remove a surface layer, typically 20-40 micro-metres in depth in the case of stainless steel.

The most cost-effective method for obtaining a clean passive surface on stainless steel is by immersion pickling in an ANOPOL formulated solution of dilute acids. Correct pickling in a formulated solution of dilute acids produces a uniform matt grey finish, the effect of chemical micro-etching.
