Wooden utensils, just as with serving boards and most cutting boards, don't need to be finished in any way to work well in their intended roles. A long while back it was the norm not to finish things like this and while it's still done today in some parts of the world in the West the idea has largely been forgotten about, or pushed aside in favour of one or another finish While there's nothing wrong with that as a goal it tends to go hand in hand with an idea that the wood needs to be finished, but very often the treatment does nothing to improve the serviceability of a food-prep item and might even negatively affect one or more attributes.

Much unlike linseed oil, tung oil is poisonous , containing terpene esters. That does however not necessarily mean that it isn't safe to use anyway. I would surely not drink it, and you should avoid direct skin contact while it's liquid. Irritations are not uncommon, and they are not necessarily of allergic nature, but also due to the poisonous effects.

Rubber gloves to the rescue. I would probably not want a child to suck on a wooden spoon for a prolonged time either, simply because you never know. But other than that, I believe that despite being poisonous, it is reasonably safe.

The amount of toxin that you are likely to take up, even from a wooden spoon, should be very small once the oil has cured, this should be perfectly tolerable without ill effects.

Some people recommend orange oil under the conception of penetration geting better also, terpentine is sometimes used. I am not convinced this is the case at all. However, tung oil is not entirely odorless, and orange oil may mask this, so there is a little value in doing that. However, do note that adding orange oil means adding a common allergen, which again works against "safety". Sign up to join this community.

This is also is a perfect alternative to some drying oils like linseed, soy, and walnuts. It comes with a distinctive smell, but not too aggressive. This is the reason why experts suggest diluting this oil with a 50 percent solvent.

This way, the application of the mixture with this substance will be easier. You can use a citrus solvent to give a good scent to its mixture. At the same time, it can eradicate all petroleum-based materials before using them to your boards and woodworking projects.

Before getting started, check if there is a presence of dust, grease, dirt or any contaminant on your wooden surface. You can strip or sand its surface to get rid of old finish or coating in there. Then, use trisodium phosphate to clean the area and sand it with sandpaper grits. Lastly, you can vacuum to clear the dust. The next step is to thin the oil for easier application.

It also promotes a quicker drying process and enhancement of penetration on the wood layers. However, there are exceptions to this step. You cannot think of this Tung oil if it will be used to unfinished and old wood floors, weathered wood, and concrete floors.

Carnauba wax is derived from the Brazilian palm tree. It is considered food-safe as it is a natural vegetable-based wax product. This wax is often mixed with beeswax as it can be difficult to achieve a consistent look when used pure. This wax will require two to three coats to provide the best coverage possible. It will not penetrate wood grain, a characteristic common with all wax products.

This material will provide a bit more durability than beeswax will in many cases, but it will wear over time and needs to be re-applied. It offers a soft feel when touched and generates a satin-like shine. Many woodworkers will apply another protective product over carnauba wax but it can offer you a coating that is non-toxic.

A popular selection for many joiners is this product made from nuts of the tung tree. Part of this popularity is due to the durability of this finish, a trait that offers hardiness as well as lower maintenance.

It also supplies wood items with decent water resistance, something that is required for food-related wood items. Is tung oil safe for food, though? Tung oil makes my list here as it is food-safe after three days of curing and repels food particles that can stick in the pores on wood surfaces. This protection will need monthly re-application to offer a high level of protection. When looking at tung oil products , make sure that they are pure.

Oil and varnish blends, as well as wipe on products, contain solvents that most woodworkers want to avoid when using on food-related items. This product is one of the oldest finishes, used by ancient Egyptians on their wooden items.

It should be noted that linseed oil does not provide the best protection against water. Scratching can also be an issue unless you cover your project with several layers. Fractionated coconut oil has been refined to the point of removing LCT long-chain triglycerides , a process that prevents this product from going rancid.

It offers users a food-safe finish that is non-toxic and has become more popular among hobbyists in recent years. It can be applied in the same manner as other vegetable-based products and will offer a softer finish for your projects.

While pre-made shellacs are available, I would recommend mixing your own.

Lead was once used as a drier but has been banned for several years now. I have found no research that indicates that the driers used today pose a health risk when applied on wooden utensils and cookware.

It is important to keep in mind that all products, especially finishes like polyurethane, are allowed to cure completely before use. That may require up to days, but it should provide a food-safe coating when curing is complete. Lacquers are similar to polyurethanes in regard to curing time.

As a matter of fact, they will usually need longer to dry than almost any other finish you will use. This type of finish should be food-safe once it has fully matured throughout the entire coating.

Another consideration is that lacquers do not penetrate the wood grain, but sit on top of the wood surface instead. That makes it an adequate finish for items that will not be roughed up, like serving trays for example.

They will tend to shed chips on cutting board surfaces, so alternative finishes may be desired in those applications. A few vegetable-based oils were listed previously that can be used as a wood finish. Most vegetable oils should be used with caution or avoided if possible. There are several reasons I suggest this. Most of these products will thicken on utensil surfaces over time and can become cloudy in appearance as well as generating an off feel to the wood surface.

Applying vegetable oils will also discolor your wooden projects in many instances, leaving them with a look you did not intend for them to have. Finally, they can become rancid and will make your food-safe wooden utensils smelling bad. As you can see, there are many food safe wood finish options out there.

Give more than one of them a try to see which you prefer working with. Keep your woodworking safe and healthy!
