What are the best application techniques for using Danish oil on black walnut wood?

The best application technique for using Danish oil on black walnut wood is to apply a thin, even coat with a clean cloth or brush, following the wood grain. Allow the oil to penetrate for about 15-20 minutes, then wipe off any excess with a clean, dry cloth. Repeat this process until you achieve the desired level of finish. Let the wood dry completely before using or applying additional coats.
