Default A Hopeless Mahogany Case ?

Folk may have seen my "Rescued Test Equipment" thread of 16th Feb. One of the items - a Demolition Test set(pictures 3 & 4) - was extensively manky!
After recently renovating the Mahogany cased "Capacity Tester", & then just finishing an Oak cased "Desynn Tester", thought I'd attempt the demolition tester's mahogany case. No one seems to want the tester, but the well constructed case, now that all the much corroded &/or rusty hinges, catches, feet, etc. have been removed, could house another future project. As structurally, it hasn't suffered any damage, and I take my hat off to the chap('AP' - who had pencilled his initials inside the battery box) who did the excellent joinery.
Maybe my efforts in mank removal & hopeful surface restoration and varnishing might help others to consider such a task themselves.
The rust & verdigris penetration of the surface should hopefully be removable, but the oil stains worry me. Any suggestions, please ?

Regards, David

Might putting uncoloured absorbent (kitchen) paper on the stain and then applying a warm/hot iron to loosen the oil so that it gets absorbed by the paper help? I have no experience of this - it's just a thought.

Getting some solvent in to make the oil more mobile, followed by contact with an absorbent material may work. Absorbent materials used for stain extraction can be paper, flour, bentonite dust, all sorts of things. Powders are better able than papers to conformally contact the surface.

God awful weather has driven me inside. Have followed Colin's & David's advice and soaked the lid(pre -warmed) in meths then weighted it down on top of some kitchen roll paper. That, along with a good scrape, then repeat sanding from P80 up to P600 has improved things greatly. Yep, there are still some deep stains which no amount of scraping & sanding will remove. But thankfully the oil residue has gone. Next - more sanding with higher grade paper, then a stain & varnish.

Regards, David
