Thanks! Yes it is a food safe finish! Look it up mineral oil & bees wax. I have been using it for years. I make mine similar to what Jim mentioned. I haven’t made any in a while. I apply it to cutting boards as needed. Maybe once or twice a year.
If you don’t want to make your own, I have found that George’s Club House wax at Woodcraft is a inexpensive and great Beeswax/Mineral oil finish. I use it all the time.
