Here’s the how to:
1) First, and most important of all—use the right type of oil. Mineral oil. Very, very important! Forget all those veggie oils—the overwhelming majority of them will turn rancid. Which can add an unwanted tinge of tartness to whatever you chop on the board and make the surface gummy and mildly disgusting.
(Here’s a brand of mineral oil I recommend: Thirteen Chefs Food Grade Mineral Oil.)
2) Apply a modicum of oil to the board, and with a clean cotton rag, spread and rub it into the wood. Repeat; repeat. (It’s better to apply the oil to the wood rather than the cloth because you’ll use less. Cloths tend to be oil hogs.) Make sure to do both sides as well as the edges, even if you only chop on one side of the board. Wood needs to absorb liquids evenly—otherwise it tends to warp.
3) Don’t over oil! Better to do a second session if need be. (If you ignore this advice, you’re going to keep wondering where all those oil smears on your countertop and clothes are coming from.)

4) After you’ve covered the entire surface, let it sit for a minute or two. Then, using a fresh dry cloth, wipe the entire board taking away any excess oil. Prop the board up with nothing touching it, so it can get as much air as possible. Allow the wood to do its absorption thing. My favorite airing-out spot is on top of the stove grills. (I do this after dinner and usually flip the board at least once.)
5) If after 4 or 5 hours the board is still moist with oil, you’ve applied too much. Take a clean cloth and rub it down again and continue to leave it out to dry. All you can do is wait—eventually the wood will soak it up. (And if you need to use the board in the meantime, go ahead. Mineral oil is virtually tasteless and won’t hurt your food.)
Enjoy the mellow shiny glow of an oil-freshened board!

P.S. If your wooden cutting board had begun to develop some minor cracking, this should help—but it can’t do miracles. It can also help with preventing warpage.
Hi – Me again,
1. How often do you recommend doing this oiling process?
2. What do you think about the John Boos wax? DO you need to use this as well – if so how often?
3. How is William Sonoma mineral oil?
1) It totally depends on how much you use your cutting board and, more importantly, how much you wash it. You can tell when the wood starts getting paler and drying out. Most new cutting boards have been oiled some, but if yours looks dry, it can’t hurt to oil it. Just make sure to wipe off the excess. And with a new board, I would definitely recommend being generous with how often you oil it because it will only help with the curing process. Always do BOTH sides. And when you wash do BOTH sides and rough dry BOTH sides with a paper towel. Do NOT let the board drip-dry soaking wet or you are asking for warpage issues on a new board! (I’m going to do a post on this, on breaking in a new board, in January.)
2) I haven’t used the Boos, but it looks great. Heck, it may even last longer and resist water more than regular mineral oil. (BTW, it has mineral oil in it.) On the other hand, you pay a premium for it, and it’s not necessary to spend that premium. Regular mineral oil will work fine.
3) William-Sonoma’s mineral oil would be fine. I think I used to use it :)
Wow – OK, amazing:
A Wusthof Classic santoku, a big Boos board, a Messermeister ceramic hone, and some good oil! Nice Hannukah present if you ask me!
Thanks for your help. Hopefully, I’ll be back soon once the knife collection starts to grow!
You can buy food-grade mineral at some drug stores, namely CVS, in my area. I dissolve 6% (by volume) beeswax in it over a hot water bath. More beeswax and it tends to separate. The beeswax is carried into the board by the mineral oil and builds up with repeated use. As the board gets saturated with wax, you will have to oil it less frequently.
And I thought I was fussy :) Thanks much for explaining about the beeswax though. . .
When I got my end cut wooden cutting board, I read an article on using coconut oil. I’ve been using it for at least 5 years and haven’t had a problem with rancidity.
On a side note re: knives. I own Cutco (yes I was a rep 30 years ago). I’m very happy with them, especially their warranty and free sharpening. Yes, I agree, they probably aren’t quite as good as your recommendations. However, they are very good knives and will “hold their own” against the competition. I am saving my money for a Bob Kramer.
Hi Dave, and welcome to KKG!
My understanding is that although coconut oil will resist much longer than other vegetable oils, it’s only a matter of time before it will go rancid. It’s the nature of the beast. Why bother messing with it when mineral oil will never spoil and is the best solution? Here are a couple of posts relating:
I have a Cutco butcher’s knife I inherited from my Mom and I have used it only for slicing salmon fillets and whatnot and it has held up OK. But that’s what I would call very light usage. What I’ve heard from others is that Cutco knives do not hold their edges. They do not publish anything about the steel they use or even it’s HRC, so that makes them rather suspect. I would be curious to perform some kind of comparative test sometime, but at the moment, it’s a low priority.
If Cutco works for you, then that’s your solution. The fact that they sharpen for free is definitely an inducement. But I’m guessing that if you tried using your average Wusthof Classic or Henckels Pro S and got it sharpened by Seattle Knives and honed it regularly with a ceramic hone that you would never ever go back to your Cutcos. But this is just an educated guess :)
It seems the recommendation is specifically for refractionated coconut oil — since it won’t turn rancid. (See the FAQ section on this page http://bestreviews.com/best-cutting-boards)
