Solid oak is a natural material that requires care to help it maintain its appearance and durability. A well-cared-for countertop ages beautifully. During the manufacturing process the countertop is treated with Danish Oil made from tung oil. The oil protects against damp and dirt, but an additional coat should be applied once a year and whenever the surface begins to feel dry. For this, use Danish Oil or another oil intended for wood furniture (available from DIY stores). Follow the recommendations on the oil’s packaging. If necessary, use a soft felt rubbing block. Wipe off any water on the countertop immediately and avoid using strong cleaning products. If a stain or a mark appears on the countertop, you can rub it down and treat it with oil.
