An electrolysis bath can remove rust very efficiently; and when the rust has gone there is no further degradation to the iron that is revealed.

Check out the video at the bottom of this link of Vegard Vike's conservation of the Langeid Sword:

This is my understanding as well - the cleaning needs to be done with a small drill and done slowly and carefully. Here is another video of a clean up, which preserves the silver decoration under all the rust deposits: https://www.youtube.com/watch?v=iw02-fWTJF4 |

I find it very difficult to believe that the 'before' and 'after' photos are of the same item & strongly suspect that there has been a mistake made in that article.
