In this article, we will detail how to remove linseed oil from wood, including all the steps and tools involved. But first things first.
Linseed Oil and Wood
Many may see this post heading and want to avoid linseed oil. Well, no. Linseed is a very useful agent in preserving wood and is even used to make the best gun stock oil finish. You can use linseed oil or tung oil to restore an old finish without stripping it.
The problem is when you’ve messed up and would like to get the linseed oil off. At times, linseed oil forms a solid layer that won’t go away. Scratching it with force will deface your wood project, and painting over it may not be a viable idea. Regardless, you still have to remove the linseed oil from the wood.

How to Remove Boiled Linseed Oil From Wood Furniture
Tools you need
- Protective gear (gloves and goggles)
- Steel wool
Quick Steps for Removing Boiled Linseed Oil
Step 1: Clean the Wood
Clean the wood with a damp rag. After proper cleaning, allow the wood to air dry completely. You don’t want to work on damp wood. Ensure the rag is damp and not dripping wet.
Step 2: Heat Water to Boil
Place water over a heat source and bring to boil. Then, gently add your acetone to a cap and place it on the surface of the boiling water. Don’t place acetone direct over the flame for two main reasons.
One, acetone is very flammable, and any mistake will spell disaster. Another reason is, acetone is quite volatile, and you may lose half of it if you place it over the heat source direct.
Step 3: Have Your Protective Gear On
Ensure your protective gear is on, and then brush acetone on the affected areas of the wood, keeping it wet. Apply little pressure as you brush.
Step 4: Scrub
Using steel wool, scrub on the affected parts to remove as much oil as possible. You can stop at intervals and allow the wood to dry to confirm that the linseed oil is gone from the wood.
How to Remove Excess Linseed Oil From Wood
Tools You Need
- Chemical solvent (Turpentine)
- Protective gear (gloves and goggles)
- Warm soapy water
Quick Steps for Removing Linseed Oil From Wood
Step 1: Clean the Wood
Clean the wood with a damp rag. After cleaning, allow for thorough drying of the wood in the air.
Step 2: Mix Turpentine
Add a little quantity of turpentine on a clean cloth and rub over the affected surface. The rubbing should be in a circular motion till the linseed oil starts to dissolve.
Step 3: Let the Turpentine Soak
Now, you wait. Let the turpentine sit for about 15 minutes, but you may leave it for up to 20 minutes for heavily stained wood.
Step 4: Wash off the Surface
Using another clean cloth, wash off the wood surface with warm soapy water. Clear the wood of any remnant linseed oil by scrubbing with a rag.
Step 5: Rinse
Rinse the wood with warm water and let it dry in the air. This is a critical step when using toxic chemicals, like turpentine, to limit contact with human skin. If there is still some linseed oil after the wood is dry, repeat the rubbing process.
