The problem with jojoba oil is that it doesn't polymerize or cure. It stays wet in the fibers. Nothing bad with that on wood that doesn't contact hot food and beverages.

But if you put wood treated with non-polymerized oil in a hot soup or if you pour hot tea into a cup finished with jojoba oil, the oil will get out of the fibers and into your hot liquid, the fiber will raise and the wood will start to feel rough after a few uses and start to get stained from your food and beverage.

But wouldn't that also be true of mineral oil?

I understand why you'd use a polymerizing oil for certain things; I guess I wonder about it as a substitute for mineral oil.
