Stop Using Mineral Oil for Cutting Boards and Utensils!

In the video titled “Understanding and Testing Food Safe Wood Finishes,” Marc Spagnuolo of The Wood Whisperer delves into the intricacies of various wood finishes that are safe for contact with food.

This tutorial is designed to guide woodworkers in choosing the right types of finishes for projects like cutting boards, utensils, and other kitchen items.

Marc starts by discussing the basic criteria for a food-safe finish: it should not react with food, alter the taste, or be toxic if ingested in small quantities.

The focus of the video is on the practical application and effectiveness of different oils that are commonly regarded as safe for food contact surfaces.

The finishes explored include mineral oil, Walrus Oil (a blend of mineral oil, coconut oil, beeswax, and vitamin E), Tried and True Varnish Oil (a polymerized linseed oil product), and pure tung oil.

Each product is evaluated based on its ease of application, durability, water resistance, and the maintenance required to keep wood surfaces protected and looking good.

Marc’s testing method involves applying each finish to wooden samples, then subjecting them to water exposure to simulate cleaning and usage conditions.

This real-world application is crucial for understanding how these oils behave over time, especially when in contact with water, which is inevitable in a kitchen setting.

Through his experiments, Marc highlights the advantages and limitations of each oil. For instance, mineral oil is inexpensive and widely available but requires frequent reapplication as it does not cure or harden.

In contrast, polymerized oils like Tried and True offer better durability as they harden and provide ongoing protection with less frequent maintenance.

Marc also touches on the importance of using pure oils rather than products labeled as “finishes” that may contain additional chemicals or solvents.

His preference for transparency in ingredients reflects a broader concern for safety and health, emphasizing the need to know exactly what is in a product before using it on surfaces that come into contact with food.

This tutorial offers valuable insights not just into what makes a finish food safe, but also into how to apply and maintain these finishes to ensure longevity and safety of kitchen wood items.

Marc’s detailed examination and practical advice make it an essential resource for anyone involved in crafting or maintaining wooden kitchenware.
