Brush loose dust and dirt off furniture surfaces with a dust brush or soft cloth. Carved details and crevices can be dusted with the dust brush attachment of a vacuum cleaner.
Mix a 1/4 cup oil soap with 1 gallon of warm water. Alternately, use just enough dish soap to make the water slightly sudsy.
Wet a soft cloth or sponge with the soapy water and wring out so it is just damp. Wiping excess water off your hands prevents it from dripping on your project.
Wipe the furniture gently with the damp cloth, using only enough force to remove the dirt. Clean a small section at a time, swishing the rag in the soapy water and wringing it out again to refresh the cloth.
Repeat the cleaning process on surfaces with stubborn dirt until all surfaces are clean. Replace the soapy water as it becomes murky with dirt.
Wipe surfaces with a fresh cloth dampened with clean, fresh water to remove any excess soap, then allow to dry.
