Understood. But iv started tests already .... And restored (mechanically) a few bikes but agreed not to perfecto standards. Not that I want that .

But I treated some very old tools father's father fathers probably a) with vinegar 5-10% then b) blueing .... To great effect.
An effect I like that keeps the used old look.

Pic of tools on left just de rusted with vinegar and right - blued. I like.

Will post the seat hinge results.
(Just trying to find a way to make my hand drill into a wire wheel .... With no garage ..... To remove any final rust from metal parts . Clamp to a table ?)

For something like those hinges, either use the special derusting sauce or phosphoric acid. Home Depot sells Kleenstrip Etch & Prep for less than $20 a gallon. It works fast, unlike vinegar. For protection, I'd either zinc plate or powder coat. Gun Blue has low rust resistance. Better than nothing, but even a rattle can spray will provide more protection.
 
Yes agree on phosphoric acid but my stock is 300m away. Vinegar is doing the trick and has to.

For protection. Iv thought about it and it has to be blueing ... Something iv only just discovered. I'll try for a season with bike outside.
As the bike is with me forever this can be a small test. I like the effect a lot.

But agree totally with your method and normally rattle can spray.
That has to wait till I get my gear , notes sorted and start on the frame in parts , outside. Not able really to fully strip down now in one go.

(I'll have to rub down parts of the frame on situ , de rust , prime and spray satin black )
 
But for motivation a full detailed clean of front end has made it look ok again. Last 3 years I have barely cleaned it. No more !!

Update on the seat hinge.

Pic 1) after 24hrs in 6-10% white vinegar
Pic 2) after my blueing

I very much like this non perfect look. I don't have the words to explain why but I like. I don't ever want this bike in prestine condition but clearly cared for.
