All our tables are covered with Rubio or Osmo oil as a protective layer. The oil serves as a barrier against stains and enhances the natural beauty of the wood. Although spills won't harm the table due to the Rubio oil, cleaning them up promptly and using cloth tablecloths, placemats, and coasters on tables when serving hot dishes to avoid any damage to the oil protection cover surface. In a few years' time, you may notice some dry areas where you can reapply for Rubio oil which can be bought on Amazon.
