Natural Oil for Wood: A Comprehensive Guide

Have you ever wondered about the secret behind the lustrous finish of your favorite wooden furniture? The answer lies in the magic of natural oils.

Natural oils, particularly the best ones for wood furniture, not only enhance the beauty of the wood but also protect it from damage. They seep into the wood, nourishing and creating a protective barrier against environmental elements.

So, let’s dive into natural oils and discover their incredible benefits for wood.

Why Use Natural Oils for Wood?

If you’re passionate about maintaining the natural beauty of your wooden furniture, especially when it’s dry and needs some TLC, natural oils are your best bet. But why should you opt for natural oils over other wood finishing products? Here’s why.

Unparalleled Nourishment

Natural oils penetrate deep into the wood, nourishing it from within. They replenish the essential oils that wood loses over time, preventing it from drying out and cracking. The result? Your dry wood furniture regains its lost luster and looks as good as new.

Enhanced Durability

Natural oils form a protective layer on the wood surface, enhancing its durability. They shield the wood from harmful UV rays, moisture, and wear and tear, ensuring your furniture stands the test of time.

Easy Maintenance

Maintaining wood furniture treated with natural oils is a breeze. Unlike other finishes that chip or peel, natural oils can be easily reapplied to keep your furniture looking its best. Plus, they don’t leave any unsightly marks or build-up.

Eco-Friendly Choice

Natural oils are derived from renewable resources, making them an eco-friendly choice. They are biodegradable and free from harmful VOCs, contributing to a healthier and greener planet.

Aesthetic Appeal

Natural oils enhance the natural grain and color of the wood, adding to its aesthetic appeal. They give the wood a warm, rich glow that’s hard to achieve with synthetic finishes.

Types of Natural Oils for Wood

When caring for your wooden furniture, not all oils are created equal. Different types of natural oils offer varying benefits, and some may be more suitable for certain types of wood than others. Let’s explore some of the best oils for wood, including those perfect for pine wood.

Linseed Oil

Extracted from the seeds of the flax plant, linseed oil is a popular choice for wood finishing. It penetrates deeply into the wood, providing robust protection and a beautiful, glossy finish. However, it does take longer to dry than some other oils.

Teak Oil

Despite its name, teak oil is not extracted from teak wood. It’s a blend of oils and varnish, designed to provide excellent protection against the elements. It’s particularly suitable for dense woods like teak and mahogany.

Mineral Oil

Mineral oil is a non-toxic, food-safe option that’s perfect for kitchenware. It’s clear, odorless, and doesn’t go rancid, making it a popular choice for cutting boards and butcher blocks.

Understanding Wood Types and Their Compatibility with Oils

Just as there are different types of natural oils, there are also various types of wood. Each type of wood has its unique characteristics and responds differently to oils. Understanding this compatibility is key to choosing the best oil for your wood furniture.


Softwoods, like pine, cedar, and fir, have a porous structure that absorbs oil quickly. However, they can also become saturated and feel greasy if too much oil is applied. Light oils like linseed or mineral oil work best for these types of wood. (Also read: Teak oil on Pine, Teak oil on cedar)


Hardwoods like oak, maple, and walnut have a denser structure. They require an oil that can penetrate their tight grain. Tung oil and Danish oil are excellent choices for these woods. (Also read: Teak oil on oak, Teak oil on walnut)

Exotic Woods

Exotic woods, like teak and mahogany, are naturally oily. They benefit from heavier oils like teak oil, which can penetrate their dense grain and enhance their natural beauty.

Chemistry of Natural Oils and How They Interact with Wood

To truly appreciate the magic of natural oils, we need to delve into the science behind how oils, including olive oil and tung oil, interact with wood.

Wood comprises a network of tiny, microscopic tubes or cells. When natural oils are applied to the wood, they seep into these tubes, filling them up. This is why oils are known to “penetrate” the wood.

Once inside the wood, the oils undergo a process called polymerization. This is a chemical reaction where the oil molecules combine to form larger, more complex molecules.

These larger molecules are too big to escape from the wood’s cellular structure, so they stay put, hardening and forming a protective barrier within the wood. This barrier not only enhances the wood’s appearance by giving it a rich, warm glow but also protects it from moisture, dirt, and wear and tear.

For instance, Olive oil and tung oil are known for their excellent penetration and polymerization properties. While not commonly used for wood finishing, olive oil can still provide protection and enhancement. Tung oil, on the other hand, is renowned for its superior protective qualities and is often used in high-end wood finishes.

Preparation of Wood for Oil Application

Preparing the surface properly before applying oil, including mineral oil, to your wood is crucial. Here’s how you can do it:

  1. Clean the Wood: Clean the wood surface to remove dirt, dust, or grime. You can use a damp cloth for this purpose. If the wood is extremely dirty, you may need to use a wood cleaner.
  2. Sand the Wood: Sand the wood to smooth out rough spots and open up the wood’s pores. Start with coarse-grit sandpaper and gradually move to finer grit. Always sand in the direction of the wood grain to avoid scratches.
  3. Remove the Dust: After sanding, remove the dust using a vacuum or a tack cloth. This step is crucial as dust on the wood can mix with the oil and create a rough finish.
  4. Apply a Pre-Stain Conditioner (Optional): If you’re working with a softwood like pine, you might want to apply a pre-stain conditioner. This product helps to prevent blotchiness by ensuring the oil absorbs evenly into the wood.

How to Apply Natural Oils on Wood

Applying natural oils on wood is a straightforward process that requires a bit of patience and elbow grease. Here’s a step-by-step guide on how to do it, and yes, we’ll also answer the question, “Can I use olive oil on wood?”

  1. Choose Your Oil: The first step is choosing the right wood oil. This could be any of the oils we’ve discussed, including olive oil. While olive oil isn’t a common choice for wood finishing due to its tendency to go rancid, it can still be used for small, quick projects.
  2. Prepare the Oil: Some oils, like tung oil, must be thinned before application. You can thin the oil using a solvent like mineral spirits. Follow the manufacturer’s instructions for the correct ratio.
  3. Apply the Oil: Using a clean, lint-free cloth, apply a generous amount of oil to the wood. Always apply the oil along the wood grain, not against it. Let the oil soak into the wood for about 10-15 minutes.
  4. Wipe Off Excess Oil: After soaking in the oil, wipe off any excess oil using a clean cloth. Failure to do this can result in a sticky finish.
  5. Let It Dry: Allow the oil to dry. This can take anywhere from a few hours to a couple of days, depending on the type of oil and the temperature and humidity of your workspace.
  6. Repeat: For a more durable finish, repeat the process a few times. Three to four coats are usually enough for a good finish.

Maintaining Wood with Natural Oils

Natural oils beautify your wood and make it easier to maintain. Here’s how you can keep your wood looking its best with natural oils:

  1. Regular Cleaning: Clean your wood regularly to remove dust and dirt. Use a dry or slightly damp cloth for this purpose. Avoid using harsh cleaners as they can strip the oil finish.
  2. Reapply Oil: The oil finish can wear off over time, especially on high-use items like tables or chairs. When this happens, simply clean the wood and reapply the oil. There’s no need to strip the old finish.
  3. Deal with Stains Immediately: If something spills on your wood, clean it up immediately to prevent stains. If a stain does occur, you can usually remove it by lightly sanding the area and reapplying the oil.
  4. Avoid Heat and Sunlight: Excessive heat and direct sunlight can damage the oil finish and fade the wood. Keep your wood furniture out of direct sunlight and away from heat sources.

Common Mistakes When Using Natural Oils

While using natural oils on wood is relatively straightforward, people often make some common mistakes. Let’s take a look at these errors and how to avoid them.

  1. Not Preparing the Wood Properly: As we’ve discussed, preparing the wood is crucial for a good finish. Failing to clean, sand, and dust the wood can result in a rough and uneven finish.
