To ensure the longevity of the carved spoons from the BeaverCraft spoon blank set, they should be treated regularly with food-safe oil, such as linseed or walnut oil. This care protects the wood from moisture, prevents cracking, and enhances the natural grain of the different wood types, such as cherry or linden. After use, the spoons should only be hand-washed with mild dish soap and dried thoroughly immediately to prevent the wood from swelling.
