Wood Care: After use, wash this product in warm soapy water and wipe dry. Apply butcher block oil on the product as the cutting surface becomes dry or after each use. Avoid soaking this product and do not use in a dishwasher. From time to time, the surface may become "bumpy". This is completely natural as we leave all of our wood in its natural state with no varnishes or lacquers. You can simply use a high grit sandpaper to smooth it out and oil it again to bring it back to new!
