Rust removal options...is Evapo-Rust any good?

[Larry D.]

I think you misspoke a little. I don't think you will find more rust where the bluing remains. However, since bluing IS rust, that can be debatable. 

A note here for the newer guys -
On most gun boards, this phrase is generally used to tell someone that they're full of crap.
On this board, it's actually an invitation to discuss the subject further and come to a generally accepted consensus. Even when one party disagrees, it's done with respect.

Come to think of it, I don't think I've a single internet crap slinging festival since I've been here.

Cause my medications are working.. but I can always sit my beer down for the ban hammer 

Besides.. we have a wonderfully talented cleaning staff and body disposal method....no one sees anything.

Appreciate the endorsement Larry. Glad you enjoy it here and we appreciate your input to the discussions.

Regarding bluing and rust. They are both iron oxides, but rust is basically all Fe₂O₃ whereas bluing is Fe₃O₄ and is therefore a mixture of Fe(II) and Fe(III), i.e., not all of the iron atoms are fully oxidized to the ferric form, Fe(III). Given the formula of Fe₃O₄, it means that on average, two of the iron atoms are oxidized ferric, Fe(III), and one is non-oxidized ferrous, Fe(II). Of course the obvious observable difference is color, "rust" is orange and "bluing" is black or nearly black.

BTW, I'm a biochemist but I understand inorganic chemistry as well

Well, I always bow to the pro's ...sometimes.  No, seriously, I kinda figured by your handle you were a scientist of sumtin. I mean I use Phosphorus on my hay field every spring FWTW. But way over my head with what steel does on a molecular level.

Good info though, I'm always willing to learn. Sometimes anyway.  One thing I'm not very good at is being serious. Life's too short.
