We will cover everything you need to know to use this natural product safely and confidently.
Understanding Food Grade Oil
What truly defines food grade oil in the context of wood finishing? It fundamentally means that the oil meets specific safety standards, deeming it safe for contact with food. This is a critical distinction from other wood finishes like varnishes, polyurethanes, and even some mineral oils that might contain solvents, dryers, or other additives that are not safe for ingestion.
When you use food grade oil for wood, you prioritize safety. These oils are typically nontoxic and derived from natural sources, making them a potentially renewable option. While many synthetic finishes offer exceptional durability, the peace of mind that comes from using a food-safe product is invaluable, particularly in areas where direct contact with food is frequent. Choosing the right product can feel overwhelming, but the health of your family is worth the extra attention.
Exploring Different Types of Food Grade Oils for Wood
The world of food grade oil for wood offers several distinct options, each with unique properties and benefits. Let’s delve into some of the most popular choices:
Mineral Oil
Typically, we are talking about food grade mineral oil. This oil is often favored for its clarity, odorless nature, and lack of color. Food grade mineral oil is readily available, affordable, and incredibly easy to apply. However, it’s crucial to understand that mineral oil does not dry or harden. It essentially sits on the surface of the wood, requiring regular reapplication to maintain its protective properties. Mineral oil can also leach out over time, so frequent upkeep is essential. You can find it in most hardware or big box stores that sell cutting boards.
Fractionated Coconut Oil
Unlike regular coconut oil, fractionated coconut oil remains liquid at room temperature, making it an excellent choice for wood finishing. It is virtually odorless and possesses good moisturizing properties, which can help prevent wood from drying out and cracking. However, it’s essential to be aware that coconut oil, even fractionated, can go rancid over time if not properly stored or applied in excessive amounts. Also, while uncommon, coconut can be an allergen for some individuals.
Walnut Oil
Walnut oil offers a richer color and a pleasant aroma, making it a popular choice for those who desire a slightly more decorative finish. Unlike mineral oil, walnut oil is a drying oil, meaning it hardens over time, creating a durable and water-resistant surface. This makes it a more long-lasting option than mineral oil. However, walnut oil is a potential allergen, which is a significant consideration for individuals with nut allergies. It is also typically more expensive than mineral oil.
Pure Tung Oil
Tung oil is a natural drying oil derived from the seeds of the tung tree. It creates a hard, matte finish that is highly resistant to moisture and mildew. Tung oil requires multiple coats and a longer drying time compared to other oils, but the resulting finish is exceptionally durable and protective. Similar to walnut oil, some individuals may experience allergic reactions to tung oil. It’s essential to ensure that you’re using pure tung oil, as some products labeled “tung oil finish” may contain additives that are not food grade.
Other Options
The market also offers other less common options like safflower oil, sunflower oil, and specialized food grade oil for wood finish blends. These options may offer unique properties or be formulated for specific applications. Always research the ingredients and ensure that any product you choose is explicitly labeled as food grade and safe for contact with food.
Where to Use Food Grade Oil on Wood: Endless Applications
The versatility of food grade oil for wood makes it suitable for a wide range of applications throughout your home, especially in the kitchen:
Cutting Boards and Butcher Blocks
This is perhaps the most critical application. Using food grade oil on these surfaces is essential to prevent contamination from bacteria and to keep the wood from drying and cracking.
Wooden Utensils
Spoons, spatulas, and other wooden utensils benefit greatly from regular treatment with food grade oil. This prevents splintering and helps keep them hygienic.
Wooden Bowls and Plates
Applying food grade oil to wooden bowls and plates protects them from moisture and food stains, extending their lifespan and maintaining their aesthetic appeal.
Children’s Wooden Toys
Ensuring the safety of children’s toys is paramount. Food grade oil for wood provides a safe and natural finish for wooden toys, preventing the leaching of harmful chemicals.
Butcher Block Countertops
Butcher block countertops are a beautiful and functional addition to any kitchen, but they require proper sealing with a food-safe finish. Food grade oil is the ideal solution.
Salad Bowls and Serving Dishes
Protect and beautify your salad bowls and serving dishes by sealing the porous nature of the wood from the oils and acids in your foods.
The Art of Application: How to Apply Food Grade Oil to Wood
Applying food grade oil for wood is a relatively simple process, but proper technique is essential to achieve the best results:
Preparation
The first step is to thoroughly prepare the wood surface. Begin by sanding the wood to create a smooth and even surface. Remove any existing finishes or coatings. After sanding, carefully clean the surface to remove all dust and debris.
Application
Use a clean, lint-free cloth or a natural-bristle brush to apply the oil. Apply thin, even coats, working with the grain of the wood. Avoid applying too much oil at once, as this can lead to a sticky or uneven finish.
Drying Time
Allow the oil to penetrate the wood for the recommended time (typically minutes, depending on the specific oil). Then, wipe off any excess oil with a clean cloth. Allow the wood to dry completely before applying another coat. Drying times vary depending on the type of oil and environmental conditions.
Number of Coats
The number of coats required will depend on the type of oil you are using and the desired finish. Generally, two to three coats are sufficient for most applications.
Buffing
After the final coat has dried completely, buff the surface with a clean cloth to create a smooth and polished finish.
Maintenance and Care: Keeping Your Wood Beautiful
Maintaining wood treated with food grade oil is essential to prolong its life and beauty.
Regular Oiling
Reapply oil regularly, as needed. The frequency of reapplication will depend on the type of oil you are using and how frequently the wood surface is used. Cutting boards and butcher blocks may require more frequent oiling than wooden bowls or toys.
Cleaning
Clean treated wood surfaces with gentle soaps and water. Avoid using harsh chemicals or abrasive cleaners, as these can strip away the oil and damage the wood.
Avoiding Harsh Chemicals
Harsh chemicals should never be used on wood finished with food grade oil. They can contaminate the surface and potentially leach into food.
Addressing Scratches and Stains
Light scratches and stains can often be removed by lightly sanding the affected area and re-oiling the surface.
Safety First: Essential Considerations
While food grade oil for wood is generally safe, there are a few safety considerations to keep in mind:
Allergies
Be aware of potential allergic reactions, especially to nut-based oils like walnut oil. Always check the ingredients of any product before using it, and avoid using oils that you are allergic to.
Rancidity
Oily rags can spontaneously combust. Dispose of oily rags properly by soaking them in water and sealing them in an airtight metal container.
Ventilation
Ensure good ventilation when applying food grade oil, as some oils can release fumes during the drying process.
Choosing Reputable Brands
Select food grade oil for wood from reputable brands that clearly label their products and provide information about their ingredients and safety. Look for certifications from organizations like NSF International.
