Wood cutting boards and kitchen utensils can be treated with tung oil so they look beautiful and last longer.
There is one little known treatment that will make your wood cutting board or butcher block countertop impervious to water and resistant to stains: tung oil.
Tung oil is the oil extracted from the tung nut of the Aleurites fordii, a tree native to China. Only untreated wood can be treated with tung oil, woods with paint or clear polyurethane finishes will not absorb the oil. Woods previously treated with other oils should be washed with soap and water and allowed to dry before being treated with tung oil.
Pure tung oil is completely food safe and can be used on anything that will come into direct contact with food. Tung oil finish is less expensive and more widely available, however because of the additives it is not considered food safe.
Tung oil is the best way to make wood cutting boards, butcher-block countertops, wooden bowls, spoons, and knife handles look beautiful and last forever.
Massage the oil in for two to three minutes, and then wipe off the extra with a cotton rag.
While it is drying set your cutting board out of the way and propped it up so it is not touching anything that would absorb the oil. To treat wood or bamboo cutting boards, wooden bowls, spoons or knife handles, go with 100 percent pure tung oil. The additives are not food safe, so linseed oil should not be used on wood that will come into contact with food. Verktyg , sv sanders, planer, routers, jointers thumb for benches is that they found a real sweet spot.
There is much conflicting information regarding which oils and substances are appropriate for use to safely maintain cutting boards or butcher blocks.
Mineral oil (sometimes called liquid paraffin) is a non-toxic, non-drying product derived from petroleum that is colorless, odorless, and flavorless. If you are worried about selecting the right mineral oil, product labeled as “white mineral oil” are considered food safe, as these are refined to a certain degree past other oils. Regular application of mineral oil will prevent cutting boards from becoming dry and brittle, which can cause a cracked board.
If your board begins to smell, one of the easiest tricks is to cut a lemon in half and run it across the entire surface. An oil derived from the tung tree originating in southern China, it is very popular in woodworking for creating a satin look with a slight golden tint. Extracted from English walnuts, walnut oil is similar to linseed oil with a few added drawbacks and benefits. An edible oil extracted from the meat of matured coconuts, coconut oil is an increasingly popular substance used to maintain cutting boards and butcher blocks. Coconut oil has a plethora of uses: as skin moisturizer, soap, for cooking and frying, and even burning for candle light. Olive oil, corn oil, and sunflower oil, should never be used to maintain a cutting board or butcher block.
A transparent, hard, protective finish or film used in woodworking, varnish is also called a shellac or lacquer.

When cutting boards and butcher blocks are not properly maintained they can become dry and crack.
Once we were versed in the machinery, it was time to choose our wood and determine our style of cutting board. Once we had our plan in mind, we cut the wood to the desired dimensions, smoothed it off using the planer and jointer, rounded off edges with the power sander, and glued together our different pieces of wood in the pattern of our choice. In woodworking, tung oil is called a “drying oil” because it naturally dries and hardens when exposed to air. It’s better than both linseed oil and mineral oil for treating wood kitchen items like cutting boards and spoons. As the years go by the cutting board will become more durable and more beautiful, much like a well-seasoned cast iron pan.
Most commercially available tung oil is “polymerized.” That means it was boiled in the production process. A board that is treated with oil also prevents liquids from penetrating the board, which is often the source of germs and bacteria. This is a good option for those allergic to bee pollen or propolis (beeswax) or simply those that are strict vegan.Coconut Oil (Refractionated)Coconut oils have recently become highly popular for a variety of purposes, especially in beauty, because it is rich is saturated fats that are good for skin health. Sometimes called “the queen of waxes,” caranauba is prized for its glossy finish and water resistance and is often used in automobile waxes, polishes, cosmetics, and even dental floss.
You can safely use baking soda to remove stubborn stains from a cutting board or butcher block. However, there are two reasons to be cautious: 1) some people are terribly allergic to tung oil as it is made from a nut tree.
Linseed oil is prized among woodworkers for its water-repelling properties and luster after being applied. This is a specifically refined coconut oil that does not go rancid and has no coconut flavor, scene and is pure liquid at normal temperatures. As touched on above, these oils experience rancidification – a process that yields a rank smell and unpleasant taste. While these products protect wood and provide a beautiful finish, they are inappropriate for maintaining a cutting board.
Here at the Sustainability Semester where we cook all of our own meals, we have certainly come to value the usefulness of the cutting board.
Everett Smith, a local woodworker, boat builder, and craftsman extraordinaire, showed us around his workshop explaining the various power and hand tools at our disposal. Everett had quite a collection of scrap wood, with everything from birch and cherry to a great-looking piece of quilted maple, which instantly caught our eye.
When the glue was applied and the wood was pressed firmly together, we left our cutting boards in clamps overnight, ensuring that the wood would set and seal together.
From homesteading, to cooking your own meals, to crafting your own wood products, there are numerous ways to be sustainably self-sufficient. Unfortunately, all fats exposed to air eventually go rancid and coconut oil is not immune (even though some bloggers claim otherwise). Like beexwax, commercially available cutting board creams and oils often contain a mixture or carnauba, beeswax, and mineral oil.
2) The name “tung oil” is often used by paint and varnish manufacturers as a generic name for a product that contains a small amount of oil or provides a similar finish.

That said, there are reports of boards that have been treated with coconut oil beginning to smell after a long period of time. This oil is good for those that would like to use a purely natural or plant based oil on their cutting board or block. Most varnishes are made from a solvent that preserves the liquid in the container and evaporates as the finish dries, leaving a binder or resin that protects the wood's surface.
After a demonstration on each machine we got to try them for ourselves, practicing with scrap wood. Some of us opted for a simple approach, crafting our cutting boards out of one whole piece of the quilted maple, while others decided to mix and match wood, undertaking various designs incorporating both cherry and maple.
Those of us who opted for a one-wood board got to work using a hand-held planer and sandpaper to smooth out the edges and surface of our boards. However, a select group of coconut oils are refined using a refractionation process, which is a fancy way of staying that the oils have been steam distilled.
To disinfect use a diluted bleach solution or soap instead.For more information on how to safely upkeep and sanitize your cutting board, read our guide on how to oil and maintain a cutting board here. Returning at a later date, we used the power sander to even out the surface of our boards, added some finishing touches, and stained our boards with non-toxic tung oil.
Emma also chose to use only the quilted maple, fashioning two chic curved-edged smaller boards. For example, we never would have thought that so much work was required to make what appears to be little more than a slab of wood.
During this distillation process, coconut oil is separated so that the long-chain triglycerides (LCT) are removed and only the medium chain triglycerides (MCT) are left. This is problematic for two reasons: 1) the substances in the varnish can be toxic to humans and 2) having little bits of varnish in food can ruin taste and aesthetic appeal. Then we got to use the jointer, a tool used to smooth off edges so that two pieces of wood can fit tightly together. Kim decided to make a daring striped board, alternating pieces of quilted maple and black cherry.
Having said this, linseed oil does not go rancid as quickly as other oils, and some people say it doesn't go rancid at all. Following that was the planer, a conveyer-belt like machine that cleans and smoothes the surface of the wood, creating a lot of wood shavings in the process. This could very well be a case of using linseed oil only if you know the source and quality.
By no means use undiluted bleach on your cutting boards or butcher blocks, as this is an unsafe concentration and could also discolor your board.
Additional machines and tools available for us to use included a chop saw, a power-sander, a power drill, a table saw, and a lathe.
We soon realized that making cutting boards, which we thought would be a simple endeavor, was actually quite complex.
