Basically a damp soft cloth is all that is required to wipe the surface down. Do not use chemical or “wood” cleaners as this only strips the timber of the natural finish. Every six months or so a dining table will require a re-application of some natural oil but this is easily done at home using a natural based oil finish and a cotton rag. Always use a trivet on the dining table when placing hot objects and don’t let water seep from a pot plant or vase as this will blacken the timber.
