When using wooden tableware for the first time, you can soak it in concentrated salt water for about 5 hours. Salt water can dehydrate wood cells, make wood more compact, and play the role of sterilization.
After soaking, take it out to dry. After drying, you can apply vegetable oil on the surface of tableware. After the oil is absorbed, apply it again, about three times. At ordinary times, it is necessary to keep the wooden tableware clean, and do not let the life dirt adhere to the surface of the wooden ware for a long time, resulting in the formation of stubborn dirt that cannot be removed. Moreover, after use, the tableware should be put in a dry place to dry, with an interval of about one month. The operation of soaking salt water and wiping vegetable oil can be repeated, so that the tableware is not easy to mildew and durable.
Be sure to keep ventilation to prevent wooden tableware from getting damp and mildew. If the weather is humid, you can dry it with an electric hair dryer, but don't use a high-temperature file.
