Cold blueing

[jirushi]

May I ask how people remove old blueing?
I have used Birchwood Casey Blue and Rust remover, but the smell is horrible, even in a well ventilated room.
I've heard that vinegar works.

Fine wire wool, oil, and elbow grease in my case

The only chemical treatment I use is rust converter if there is pitting.

You’re going to have to polish anyway so I can’t see a benefit in trying chemical removal?

White vineger works.Degrease the parts,then submerge in vinegar.

Hi .
Do you guys fully strip the metal work down to the bare metal like you would do for traditional hot blueing?
Cheers

I do, anyway. Imho the quality of the finish is more or less entirely dictated by the quality of the prep. I’m sure if you started with a partly blued item the cold bluing would never be uniform

It’s not great stuff.
