cleaning the blade

[sirek]

has anyone experienced to remove rust on a blade by using:

electrolytic derust?

(with: water,commercial soda, and electricity)

by using this method the iron would not be affected, only the rust wil get loose.

I see several good results on the net how things in this way get derusted, but before I wil try this, maybe anyone ever tried this before and give me any advice.
