Olive oil has been recomended in the past for leather care and I question that,as it gets rancid. I guess this is not an issue if the metal is then going to be cleaned and if oiled regularly, not an issue with it going rancid and getting gummy.
For polishing/sanding work as well, I would question the use of such a heavy viscosity as any olive oil I am familiar with, as lighter oils (or solvents, or water) will float the debris more easily and not plug as heavier oils will.
Enlighten me to the virtues of olive oil. I guess that is as simply I can ask.

Hi Hotspur,
Olive oil is the so-called tree oil (German
Baumöl) that is mentioned in 17th century armory books as the optimal means of cleaning, together with
Schmirgel (sand), and preserving iron surfaces, be it armor or arms. Olive oil is the yellowish patina on untouched surfaces of antique arms; if you clean it off you will get a perfectly preserved milky white iron surface with no rust.
I have been using it in my almost 40 years of conservation practice and will stick to it as it is the historic recipe and has proved to work just fine. During the cleaning process you will get no scratches on the iron surface, nor an unnatural shine afterwards.
Best,
Michael
