Metal De-Corroder and its effects

I would personally recommend applying Renaissance Wax which is used by many museums to protect valuable objects.

I've bee steadily working my way through our collection, applying Renaissance Wax to the hard surfaced objects where it seemed appropriate, and the results are indeed good. It's a very highly regarded product, not least because the coating it gives is both attractive and durable. I'm still unwilling to use it on leather, despite being informed that it's safe to do so, but it's excellent for metal and wood, from what I can gather.

The etching of the metal is indeed troubling. The sword displayed in the first picture was treated with Pre-Lim polish after being treated with the de-corroder, which may go some way to explaining its better finish than the tested area of the jezail barrel, but I remain cautious. Perhaps, if I am to use this at all, I shall have to apply it to each spot of rust individually (which will mean taking about 6 months to get it off); or perhaps there's just nothing more to be done for this barrel, much as I'm very sad to admit it.

A very gentle way to remove rust .
Immerse and brush daily, then put it back in to soak .

Keris collector's standby .

You know if you use pure sulfuric acid it will just eat all that rust away, along with any steel, brass, silver, horn, etc.

That would certainly cut the Gordian knot; one is reminded of the Ameglian Major Cow from The Hitch-Hiker's Guide to the Galaxy: "I know many vegetables that are very clear on that point, sir; which is why it was decided to cut through the whole tangled problem by creating an animal which wanted to be eaten, and was capable of saying so clearly and distinctly. And here I am! (Baah.)"
