The timing of this is sort of uncanny as it's been on my mind a lot lately.
Generally I use a beeswax and mineral oil finish, sometimes this other product I can't remember the name of made from flax oil.
I've been wondering why jojoba oil doesn't get mentioned more in these discussions, either in combination with something else or on its own? It's a wax but liquid at room temperature, and seems to be stable for a long long time, long enough at least that it would probably need some refinishing before it might go bad.
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.
