So any way I am planning put these into a vat of Molasses which is natural product and has reportedly had some brilliant results on both ferrous metal aka Steel ~ and brass ~
I have a test lot down now with one soaking a 3" mortar tail fin - steel ~ and another with misc brass , copper and a sad nickel plate spoon ~
Will report back on results ~

Oxalic acid is good for iron / steel based items. You can buy it in crystal form and make up the solution yourself. A 1kg tub would make 10 litres of a 10% solution which should be enough to submerge your items in the right sized container.

But please be carfull with oxalic acid! Do it outside out of the wind , with chemical gloves!
Informe your self well regarding anything chemical you use .And read "Toxicity and safety"paragraph on,
Oxalic acid - Wikipedia, the free encyclopedia

No need to go to Wiki.......we have the information in a sticky thread in this very forum

Thanks for the input Blokes..
I actually pulled the 4.5" out of the 'vat' this afternoon after returning form an an amazing recce this morning... and the result is &*^*^ amazing after some ten days ~
I will to some pictures in the next few days `
(I have some four 'vats' running at present ~ either steel as in shell cases or brass ~ )
-
I finally pulled the first test artillery shell out of the Vat containing Molasses ~ the result is absolutely spectacular ~
Removed.. brushed and hosed to remove the residue ~
Truly amazing result

That 4.5 looks lovely. And to think you just picked it up off the ground. Is there any date on it?

Cheers ~
At this point, it have only found the engraving of 'BHP 5540 MO ' BHP is the traditional 'BIG AUSTRALIAN' ( Broken Hill Prop) steel manufacturers ~
I will look again but have not seen a date ~ but suspect it would be <1940s> ~ although the 4.5" were hang over from the First World War ~
And yes it/ they have suffered extreme heat < 45 deg plus> and severe wet ~ and even fire damage for 70 years ~ pretty amazing!
