Do I understand correct that Mineral oil for a butcher block top is the same sold as a laxative ?

That is correct.

But, if you read the label and note the laxative dosage, it should be obvious that, even if there should be any transfer to food prepared on the block, the amount transferred, distributed across the consumption, will be far, far less than the dosage amount.

I have always heard that mineral oil is not particularly satisfactory because it does not harden or dry.

Here is what the Highland Hardware website says about the Walnut oil they carry: "Mahoney's Walnut Utility Oil finish is just the thing for bowls, butcher blocks, salad tongs, and even wooden kitchen knife handles. It is pure California walnut oil which is heat-treated to penetrate deep into the wood, harden and leave long-lasting protection without toxic driers. Like raw walnut oil, it imparts little or no flavor or odor, nor will it go rancid. Unlike mineral oil-based finishes, these will not evaporate over time. And it leaves a beautiful surface!"

Mineral oil is best, You do not went it to harden

Pure California walnut oil heat treated to do what??? Comeon... you can't seriously believe that mumbo jumbo! Mineral oil will evaporate faster than heat treated walnut oil??? I'm gonna need some documentation on that one. But it's all a great way to get you to spend ten times as much money as you need to for block oil. Mineral oil is oderless, tasteless, penetrates as well as any other oil is completely safe for food contact, will not turn rancid and, if you buy it at the drug store instead of the woodworking supply place, can be had for a few bucks a quart.

Shave some gulf parrafin wax into a jar of mineral oil, heat that jar in some boiled water (call it the poor man's double boiler) and then apply the wax/MO mixture on your surface. It will give you a bit more protection than the straight Mineral Oil.

FWIW, most Krogers sell Mineral Oil in the pharmacy section. There is no reason to buy anything other than the generic, which Kroger periodically sells 2 for 1 with their plus card. Who knew they could develop loyalty with discounts on this stuff? Ionly stumbled onto their sale when I was first applying the finish to the top of my island.

+1 on the paraffin/mineral oil mix, it's what I used on this Jatoba/Hard Maple block.

I go through a couple of quarts a year at school when we're doing the cutting board project. The hands down cheapest place I have found so far has been Target, although the do look at me a little funny in the checkout line.

BTW you haven't lived until you have graded a couple of dozen cutting boards that the students have oiled up on the theory that a LOT more is better....I now make them turn them in unoiled, and they oil them after grading.

I saw someone on the DIY channel using cooking oil (I presume it's regular old vegetable oil) and mentioned to my wife that it didn't look right. She informed me that people had been doing it for years. Wonder how mineral oil compares to that?

also baby oil is mineral oil. In my store, mineral oil is located in both areas under different brands. So, I always purchase the best buy at the time.

I switched to using thinned varnish quite some time ago and have applied it to dozens of items, including the monster below.-it's so much better in every way. Lasts longer, less messy and looks great.
Came across the idea on the Woodwhisperer's site.

Mineral Oil is currently the only FDA approved finish, if that is a concern (resale perhaps). I like walnut oil but some people have allergic reaction (like peanut oil). I find the best finish for boards, although not the easiest) is 1-2 coats of pure mineral oil followed by a coat of mineral oil and bee's wax).

Agreed, not a good product to use! Although it isn't really visually apparent when it happens, vegetable oil does go bad after a while and can present a health hazard in wood items used for food prep.

Originally, I tried General Fininshes Salad bowl finish... but the boards lost their shine after they got wet. Now, I use mineral oil, 1.88 a quart at Walmart.

I also vote for the mineral oil w/ paraffin/beeswax melted in. Run it in thick and scrape off the excess when dried.

Keep in mind that with cutting boards, that is boards intended to slice or use a knife on the surface, the purpose of the finish is to keep bad stuff out. Even Watco once cured is perfectly safe and I am personally skeptical that even if it were not the amount of contaminant from a knife edge seems very small. The idea here is to fill the woods pores so citric acids and meat juices and fat do not soak into the wood. This is where bacteria and mold can grow. Some woods like Hard maple and bamboo are naturally bacterial resistant. Bee's wax is also resistant to bacterial growth, to protect baby bees I assume. The mineral oil finish is perishable and needs refreshed from time to time. I might mention I make cutting boards and pastry boards for sale and so I had to do a lot of research on this topic, even checking with a lawyer on the FDA regulations. I did write to the Food Channel about the vegetable oil recommendation but received no reply.

Pure California walnut oil heat treated to do what??? Comeon... you can't seriously believe that mumbo jumbo!
It’s always a crapshoot whether to believe claims about products. Since we can’t even begin to be experts on the literally thousands of items offered to us in commerce, we end up using our life experiences to evaluate product claims. For instance, in this case of a claim to “heat treated” oil one might logically connect the process to that of boiled linseed oil. And then conclude, without really knowing anything about the chemistry of the product, that the walnut oil has beneficial properties similar to those of boiled linseed oil.

So, mumbo jumbo or solid chemistry? I can’t tell. Could be either one. But the fact that a very respectable vendor vouches for the product lends some credence to the notion of a product’s quality.

Anyway, I’ve learned here that mineral oil works well (if I can believe all the assertions) and will give it a try. Actually, I hope to do a side-by-side comparison with walnut oil—then I will have a much better idea of what to believe. This test will require obtaining the oils, making identical cutting boards, and the passage of time. Look for the results in a future thread here on the Creek.

What a great article! I completely agree. When I conversations with a lawyer, the advise was not about safety, which was concerning, it was about being able to show a FDA approved stamp on what ever you used( this applied to the glue Titebond III as well). It is a litigious society. There is a tendency in our society to think that an FDA approved or at least meets FDA requirements is safe that all others are thus not safe. The FDA does not test all finishes, only those brought to their attention. I eat salad from bowls I made finished with Danish Oil and have no reservations (well other than this twitch). But if you go on TV and recommend a finish then you might have someone take issue with you.

Baby oil often has fragrance added, so might not be suitable for food contact pieces.

An excellent treatment for wooden food preparation surfaces like cutting boards and butcher blocks is a mixture of mineral oil and either paraffin or beeswax. This is what is used on many commercial wood surfaces. It will last longer and be more protective than just mineral oil. Mineral oil can be found in most supermarkets in the pharmacy section or in a true pharmacy. Paraffin is found in the canning section of the store or in a hardware store.

Heat the oil in a double boiler and shave in some wax. The exact proportions are not critical--a 5-6 parts of oil to one part of wax will work fine. Stir the mixture until all the wax is liquefied. Apply the mixture heavily and let it set 10-12 hours or overnight. Next day do it again and continue until the wood will no longer absorb the finish. Let it set for 10-12 hours and then lightly scrape off any excess. Then buff it with a rag.

Reapply whenever the wood begins to look dry.

Never put a wood board in the dishwasher and don't soak it in dishwater for long periods.

I use walnut oil which you can get at any health food store. A lot of people use it for cooking.

Jerome Hanby
02-11-2010, 2:02 PM
That's exactly what I said... I knew that olive oil would, so I thought maybe I had it wrong. I didn't pursue it since using anything out of the kitchen for finishing would beat me out of a visit to Woodcraft ;).


God I hope not, vegetable oil goes rancid after a while.

According to a post last week, oils can be used only on what they are made from (or named after) so walnut oil on walnut, mineral oil on minerals, baby oil on babies (BTW what is that made from). :D Sorry, no hijack intended.

I was going to start a new thread, but perhaps I can ask here....

I used Mineral Oil on an endgrain cutting board made from Padauk, Walnut, Maple, Zebrawood, Cherry and Purpleheart.
I've realized once the oil was on, that there are a few areas where some palm sander marks have been highlited....can I continue sanding an oiled board without the risk of the padauk or walnut staining the maple or the cherry?

Robby Tacheny
02-11-2010, 6:59 PM
Chris,

You might want to tray a card scraper instead. I have had padauk dust stain maple and poplar. Othewise maybe you can tape the light sections off if the oiled has soaked in pretty well.
