Clean the surface normally with a damp cloth with an organic soap. To keep your table in the best possible condition, you should clean the table top with the finest sand cloth once every two years. The table top is then treated with a natural mat wood oil or wax. Let the oil/wax impregnate for 15 - 20 min, and dry the rest. Use a clean cloth to finish and polish the surface at the end. Please follow the instructions for the oil blend product you are using. (Natural treatment sprays can also be used. NB: Do not use silicone-based or other non-natural treatment oils or waxes.)
