Choosing solid wood furniture is an investment in the value of natural materials. Each piece natuarally responds to changes in temperature and humidity. As solid wood responds to dry air by losing moisture, it shrinks slightly. Joints may part slightly, or a few tiny openings may appear on solid wood surfaces. These are natural responses, not manufacturing defects, and do not affect the strength and soundness of the furniture.
As the humidity rises, the joints and tiny openings will close again. You may choose to dehumidify or humidify depending on your environment. Recommended humidity is 35% to 45%. Extreme temperature and humidity changes may ruin wood.
We recommend simply using a damp cloth to clean your table. Periodically, however, use a furniture polish that's recommended for wood furniture to maintain its natural luster. Never use a polish containing silicone to clean your furniture as this makes it very difficult to refinish your furniture (should it ever be necessary).
