How to Make Walnut Oil for Wood

Learning how to make walnut oil for wood starts with understanding that you’re essentially extracting oil from walnuts.
 
There are two main ways to make walnut oil for wood: cold pressing and oil infusion.
 
Here’s how each method works.
 

1. Cold Pressing Raw Walnuts

Cold pressing is the traditional way to make walnut oil for wood, and it gives you the purest result.
 
Start with shelled, raw walnuts — about two cups will yield a small batch of oil.
 
Grind them in a food processor until they form a thick paste.
 
Then spread the paste onto a clean cloth and squeeze it over a bowl to release the oil.
 
This method takes patience, but the oil you get from making walnut oil this way is top quality.
 
You can also use a dedicated oil press if you plan to make walnut oil for wood regularly.
 

2. Oil Infusion Method

If cold pressing feels like too much work, the infusion method is a simpler way to make walnut oil for wood.
 
Chop raw walnuts finely and place them in a clean glass jar.
 
Cover them with a carrier oil like linseed or mineral oil, then seal the jar.
 
Let it sit in a warm spot for two to four weeks, shaking it every few days.
 
Strain the mixture through cheesecloth, and you’ve got homemade walnut oil for wood ready to use.
 
This method is slower, but it’s a reliable way to make walnut oil for wood without special equipment.
 

Why Walnut Oil for Wood Works So Well

Walnut oil for wood has been a favorite among woodworkers for centuries, and for good reason.
 
Here’s why this oil is worth the effort.
 

1. It Penetrates Deeply

Walnut oil for wood soaks deep into the pores of the wood rather than just sitting on top.
 
That means it nourishes the wood from within, keeping it flexible and preventing it from drying out.
 
This deep penetration is why walnut oil for wood gives such a rich, natural finish.
 

2. It’s Food-Safe and Non-Toxic

Unlike many commercial finishes, walnut oil for wood is completely food-safe once cured.
 
That makes it perfect for wooden bowls, cutting boards, spoons, and butcher blocks.
 
So if you’re finishing kitchen items, walnut oil for wood is one of the safest choices around.
 

3. It Enhances the Grain

Walnut oil for wood brings out the natural beauty of the grain without leaving a glossy plastic look.
 
It gives wood a soft, warm sheen that deepens over time.
 
That’s why so many woodworkers reach for walnut oil for wood on fine furniture and decorative pieces.
 

How to Apply Walnut Oil to Wood

Once you’ve learned how to make walnut oil for wood, applying it correctly is the next step.
 
Here’s how to get the best results with walnut oil for wood.
 

1. Prep the Surface

Sand the wood smooth and wipe away all dust before you apply walnut oil for wood.
 
A clean surface helps the oil absorb evenly.
 

2. Apply Thin Coats

Pour a small amount of walnut oil for wood onto a lint-free cloth.
 
Rub it into the wood along the grain, then let it sit for about 15 minutes.
 
Wipe off any excess oil so the surface doesn’t stay tacky.
 

3. Let It Cure and Repeat

Apply two or three more coats of walnut oil for wood for a deeper finish, letting each coat dry fully.
