Dust antique wood once a week, lightly, with a soft, lint-free cloth to remove surface dirt.
Barely dampen another lint-free cloth with water. Wipe a small section of the wood surface gently to dislodge stubborn dirt. Follow immediately with a dry cloth, buffing it until it is fully dry before moving on to another section. Repeat until the entire surface is clean and dry.
Use a light coating of lemon oil to moisturize and protect antique wood without destroying patina. Wipe it on one small area at a time and follow with another cloth, buffing until the wood glows. Do this once each winter, when humidity is the lowest and wood becomes dry.
