Update: This is the 7th day of soaking this blade in white vinegar (cooking sort).
I thought it was ready but after killing the acid with bicarb, gently scrubbing with creme cleanser and hairdrying, while it's mostly white, some either rapidly forms or becomes visible on some parts. Also some of the pamor comes out a glittering, slightly brass colour.

I was fairly sure I got the rust out from the crevice between the gonjo and blade, and it appears clean when dry, but rust appears again.

I am using a bristle brush to scrub it (slightly harder than a hard tooth brush) and when there were stubborn, harder chunks of rust I used a precision pick.

Is there something I'm doing wrong here, or is it just a matter of soaking for longer? I've removed from the soak, killed the acid and dried on days 5 and 6 also, and the same rust / brass colouring appears.
