Using your Coastal Teak Dining Table is easy. To extend the table, simply pull out the hidden butterfly leaf and set it in place. You can then use the 2 - inch umbrella hole to add an umbrella for shade. When not in use, just retract the leaf. For maintenance, clean the table with a mild soap and water solution regularly. Avoid using harsh chemicals as they can damage the teak finish. Since teak is a natural material, it will develop a patina over time, which adds to its charm. If you prefer the original color, you can apply a teak sealer once a year. Keep the table covered during extreme weather to protect it from excessive moisture and sunlight. And remember, because each table is unique, it may have some natural grooves and rustic features, which is completely normal and part of its character.
