Oils for your bamboo cutting boad: mineral, coconut or vegetable

There is so much information about which oils and substances are recommended to safely maintain cutting boards or butcher blocks. How to treat a bamboo cutting board? We put together a list that will help identify which products you should use to both sanitize and keep your board looking beautiful for years to come.

Safe Oils for Your Bamboo Cutting Board

Cutting boards, being simple slabs of wood, may not seem like they need much attention. But they do. Wood is a natural, porous material that changes through time. Therefore, we need to know how to maintain and how to oil a cutting board bamboo.

Mineral Oil

Mineral oil (sometimes called liquid paraffin) is a non-toxic, non-drying product. It is colorless, odorless, and flavorless. This oil has wonderful properties. It can prevent water absorption, which makes food-grade mineral oil a popular choice for wooden kitchen items such as wooden spoons, bowls, and, of course, cutting boards and butcher blocks. The important keyword here is food-safe, as there are types of mineral oils that are not safe for human consumption. How to select the right mineral oil? It is not as hard as you may think. Products labeled as “white mineral oil” are considered food safe. Why?  These are refined more than other types of mineral oil. Always make sure to carefully read the product's labeling if you are unsure about its proper use.

Beeswax

Beeswax is also a popular choice for cutting board maintenance. It's a natural wax produced in the beehives of honey bees and has a variety of applications. Use beeswax to hydrate, shine, and waterproof a cutting board.  You can buy ready to use conditioners in bottles. But to make your own, you can melt 1 part beeswax and combine with 4 parts mineral oil in a pot to make your own blend.

Carnauba

Sometimes this is called Brazil wax. This wax is derived from the leaves of a palm tree native to Brazil. ‘The queen of waxes’,  carnauba is water-resistant and creates a really glossy finish.  Interesting fact: this oil is often used in automobile waxes, polishes, cosmetics, and even dental floss. Like beeswax, commercially available cutting board creams and oils often contain a mixture of carnauba, beeswax, and mineral oil.

Coconut Oil (Fractionated)

Coconut oil has recently become highly popular for a variety of purposes.  Especially for beauty because it is rich in saturated fats that are good for skin and hair health. Unfortunately, all fats exposed to air eventually go rancid and coconut oil is not immune. On the other hand, a select group of coconut oils is refined using a fractionation process. It helps remove long-chain triglycerides (LCT) and only the medium-chain triglycerides (MCT) are left. As a result, we get an almost pure oil that will NOT go rancid. This type of coconut oil is great for treating not just cutting boards, but your kitchen utensils, salad bowls, countertops... you get the idea.

Lemon juice

Has your board begun to smell bad? One of the easiest tricks is to cut a lemon in half and rub it across the entire surface. The natural lemon oil also forces any soluble materials to be removed as well.

Use with сaution

There are oils that really dangerous to use for cutting boards from bamboo. We put together the most popular oils that are needed to use with caution. 

Walnut oil

Walnut oil has a few drawbacks and benefits. First, it comes from a nut, so be cautious for allergic family members or guests. It is also quite expensive and will eventually go rancid. The one benefit is that walnut oil smells great!

Coconut Oil (Refined, Virgin or Non-Processed)

As we have mentioned, coconut oil is an increasingly popular substance used to maintain cutting boards and butcher blocks. Because of its high saturated fat content, it is slow to oxidize. Therefore, it is resistant to rancidification. That said, there are reports of boards that have been treated with coconut oil beginning to smell bad after a long period of time. Coconut oil has a plethora of uses: as a skin moisturizer, soap, cooking and frying, and even burning for candlelight. It is also nut-free despite its name!

Not Recommended

The last group of oils is not recommended to use for maintaining your cutting board. You should understand that not all oils are the same. The different types have different purposes, therefore, you should definitely know about these oil types to save yourself from harmful chemicals.

Vegetable Oils

Olive oil, corn oil, and sunflower oil should be used to maintain a cutting board or butcher block. These oils will go rancid. It is very dangerous, as it is a process that yields a rank smell and unpleasant taste. As a cutting board touches your food, substances that can turn rancid should be avoided. Food should always be tasty!

Varnish

The varnish is also called shellac or lacquer.  These products are inappropriate for maintaining a cutting board. But, shellac and lacquer protect the wood and provide a beautiful finish. Most varnishes are made from a solvent. It preserves the liquid in the container and evaporates as the finish dries. As a result, it leaves a binder or resin that protects the wood's surface. This residual resin will chip and peel off when exposed to sharp objects like knives. This is problematic for two reasons. Firstly, the substances in the varnish can be toxic to humans. Secondly, varnish can ruin the taste and aesthetic appeal of food.

How to treat a bamboo cutting board

The goal of board oil is to penetrate the wood. It helps to stop any other liquids (blood, bacteria) and moisture from soaking into the board. Therefore, it is important to maintain your cutting board right. To get more information about it you can read our article 'How to care for your cutting board'. A well-oiled cutting board will keep the same shape when the wood fibers are saturated.

You wrote, under the heading “Vegetable Oils”: “Olive oil, corn oil, and sunflower oil should be used to maintain a cutting board or butcher block.” It should be: “… sunflower oil should not be used to maintain …”

And re your main headline: “OILS FOR YOUR BAMBOO CUTTING BOAD: MINERAL, COCONUT OR VEGETABLE”

It should be: OILS FOR YOUR BAMBOO CUTTING BOARD: MINERAL, COCONUT, OR VEGETABLE

(“Board,” not “Boad”)

Under “not recommended” oils you say olive, corn & sunflower oil “should” be used but says they are dangerous. Is this a typo that should read “not” be used?
