Problem with using motor oil is all the additives in it, they are toxic and can absorb through your skin... but it is a good lubricant otherwise.
PB Blaster might help remove rust spots... but there are other products that would work for this.
I have been using industrial grade oil and aluminum grease designed for use on food handling factory equipment. So it is food safe, and designed to work in high moisture, acid, salt, and other harsh conditions. It works very well.
I am around enough deadly chemicals at work... I am looking to switch to biodegradable cleaners too. Lower my exposure a little at least.
