In general, natural oils used for wood treatment are considered safe and environmentally friendly. Natural oils such as Linseed Oil, Tung Oil, and Hemp Oil are non-toxic and safe for humans and pets when used correctly. However, it is important to note that oily rags should be handled with care as they can spontaneously ignite if not disposed of properly.

Natural oils are biodegradable and renewable, making them environmentally friendly choices. They do not release harmful volatile organic compounds (VOCs) that contribute to indoor air pollution and climate change. Furthermore, natural oils penetrate deeply into the wood, nourishing and protecting it from within. They help prevent wood from drying out and splitting while enhancing its appearance.

However, it is important to note that not all natural oils are created equal. Some may require more frequent applications or may not offer the same level of protection as modern oils made with waxes, resins, and mineral solvents. Additionally, certain oils, such as linseed oil, can take a long time to dry.

In summary, it is recommended to conduct research and choose an oil that is suitable for your specific project and addresses your environmental concerns.
