Dust frequently with a clean, very lightly damp, lint-free cloth.
Frequent dusting will remove abrasive buildup which can damage a finish over time.
Avoid exposing your furniture to strong sunlight, heat outlets, open windows or dampness, prolonged exposure to direct sunlight can fade the finish of your furniture while extreme temperature and humidity changes can cause cracking or splitting.
Do not place very hot cups, pots or serving dishes directly onto surfaces.
Do not expose your furniture to any liquids and never allow water to sit on your table. Alcohol, nail polish and perfume are also dangerous because they can dissolve the furniture finish on contact and may require professional repairs.
Simply wipe, dust off, the less maintenance the better.
