I use Kevins recipe of beeswax and mineral oil. A little goes a long way. Like Bill said a gallon of mineral oil would last a long time.
i also use shellac, which is food safe, quite often.
if I know I will be sitting a piece for awhile, I will use Minwax Antique Oil, but it does take a bit to cure. It’s also my favorite finish to use.
I agree with BadBob. Key word is cured.
