Electrolytic rust removal - please add your experiences!

[RobT]

Hi All,
I am posting before and after pictures of two African daggers that have undergone electric rust removal. The first, a Hadendoa dagger, has been very badly consumed by corrosion. The second, a Tuareg dagger, was rusted on the upper half of the blade and only lightly pitted. After immersion in the electrolyte bath, both blades were rubbed down with a 3M abrasive pad. Even though Ann cautions against this method, it appears to me that the proceedure yields good results. Perhaps the preservation needs of archaeologists are different than those likely to be encountered by the average blade collector? I would appreciate it if members would take a look at the results and offer feedback. I would especially welcome the advice from members that have successfully gotten rid of the grey staining that remains on blades once the rust has removed. Is there perhaps a poltice of some kind that can take care of this? The last image in this post is the Hadendoa sheath. For those that wish to see the Tuareg sheath, it can be found on the thread titled "Large Sudanese Dagger for Comment" by Louieblades.
Sincerely,
RobT
