Untreated wood in the outdoor area patinates over time and becomes silver-grey at the end. If you want to preserve or intensify the original dark/golden/honey brown color, use Skagerak's natural oil for garden furniture. The oil is designed to protect wood species such as teak, western red cedar, cherry and mahogany. Since the natural oil saturates and darkens the surface a little, it brings out the natural beauty of the wood and leaves it well-groomed, water, dirt and grease resistant.
