All wooden table accessories are finished with a food-safe lacquer. The products can be washed by hand in lukewarm soapy water, but they are not suitable for the dishwasher. Do not soak them in water. If the varnish has worn off, we recommend wiping the product with a cloth soaked in some walnut or salad oil. To prevent drying out, never expose the wood to direct sunlight or store it near heating appliances. This may cause the wood to warp or break. The wooden boards are hard enough to serve as a cutting board and soft enough to keep the knife sharp. However, scratches caused by knives are inevitable.
