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 sanding cloth once every two years. The tabletop is then treated with a natural mat wood oil or wax. Let the oil/wax soak in for 15 - 20 minutes, and wipe off the rest. Use a clean cloth to finish and polish the surface at last. 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.)
