Dust it well
Make sure you use a soft, dry cotton cloth to wipe any dust off.
Minimal exposure to sunlight
Be careful about exposing wooden furniture to sunlight for prolonged time periods.
Be mindful of temperature
Avoid using extremely hot and cold objects on wooden furniture for better maintenance.
Let it age with grace
Furniture ages with time. Some wood may lighten and some may darken with the passing days.
Keep sharp objects away
The scratches may look very ugly if not designed intentionally.
Avoid Water For Cleaning
If you really must use some water, then try with warm water and mild dish soap to clean furniture. Be careful not to soak it for longer time periods. After cleaning the dust immediately wipe residual moisture with a cloth.
