Exactly- If it works for me like the engineer has found it works in other applications it truly IS the magic bullet and will allow exactly that- rust removal for an entire blade scales still on and zero hand work.

Imagine a fleebay special with surface rust, a simple dip/soak and you know exactly what you have under there without descaling, sanding, grinding, etc.

It may even remove those black spots we all know without refinishing the blade.

First is testing for scale damage, then comes gold wash and black spot testing.
