Danish oil is a penetrating finish used to give wood a slight shine. Due to its penetrating nature, this oil should be used only on wood that was finished with oil or another type of penetrating finish. If the wood's finish consists of lacquer, shellac, or varnish, the Danish oil will simply slide off the coating and provide no benefit to the wood. On wood finished with oil, however, Danish oil can be used as part of the cleaning process to help brighten the wood and protect it from dirt, dust and greasy residue.
Dust the wood with a dry cloth to remove any dirt from the surface. If you find a greasy or sticky spot on the wood, use a cloth moistened with water to wipe it away.
Apply a thick coat of Danish oil to the wood with a paintbrush. At this point, do not worry about making the coat look perfectly even or smooth.
Wait approximately 30 minutes to give the oil time to soak into the wood.
Rub the wood with a green scrubbing pad in a circular motion until most of the oil is wiped from the wood. The colour of the wood may darken slightly during this process.
Wipe the wood furniture with a clean rag to remove any Danish oil remaining on the surface.
Repeat Steps 2 through 5 to apply additional coats of Danish oil to the wood. You can add as many coats of oil as necessary to achieve your desired result.
