How to make a wooden secret box (using the laser cutter)

Step 3 Treating the wood

Because the laser cutter actually burns the wood, it will leave ashes on the cut borders and a strong smell that goes along with it.
My advise is to first leave the wooden pieces outdoors overnight to get rid of the smell, and then to clean the borders with a piece of wet fabric.

Then, apply the Wood Finish color of your choice. I only used one layer to still see the lines of the wood.
Let it dry for 6 hours.
