Hello Detlef,

The blade wasn't corroded so much that the bath was required.

I beg to differ: There are several deep cracks which surely were filled with rust. There is no way that a gentle polish of the surface would have removed these pockets of residual rust. Thus, for long-term preservation a limited acid soak was not a wrong strategy; with good planning, the process could have been shortened though.
Hardly any harm done in this case - we all have seen much worse restoration attempts, I believe!
Regards,
Kai
