Off to purchase some coconut oil!
I would 100% avoid coconut oil or any organic oil for wood. It can go rancid and ruin your tools.
You can buy food grade mineral oil from your local pharmacy. Just rub some on with a cloth, and keep applying as long as the wood will soak it.
Reapply when the wood lightens.

Same. This stuff is excellent and I’ve used it for years on cutting boards and butcher blocks I’ve made. It’s all natural, obviously food safe, super easy to apply with a paper towel or cloth, and the bottle lasts forever.
Mineral oil is a petroleum distillate, a byproduct of fossil fuel production. I’m not saying it’s necessarily unsafe or unethical to use, but calling it “all natural” is a bit of a reach.
I’m curious about the bacterial growth factor that can occur with wood. Saying these things can last a lifetime without even mentioning the bacteria they can absorb and harbor makes this read more like an ad at some points.
You probably don’t want to use plastics if you’re concerned about bacteria.
