To keep a wood dining table in prime condition, clean it regularly with a soft cloth and mild soap. Use coasters and placemats to protect against heat, spills, and scratches. Place the table away from direct sunlight and heating vents to prevent fading and warping. Humidity control is essential; use a humidifier or dehumidifier if needed. Periodically polish or oil the table to maintain the finish and nourish the wood. For tables with a softer finish, consider a protective glass top. Proper care can keep your table looking beautiful for decades.
