Walnut Oil Paste Wax provides a smooth surface on which the wax can be deposited. The wax is applied to the piece after final sanding and is then buffed with a soft paper towel. The Walnut Oil Crystal wax relies on the solvating properties of walnut oil, the microcrystal wax provides a translucent wax finish. In exchange for a slightly brighter shine, you get a slightly softer finish than with carnauba wax. Cutting Board Wax is a Hard, Carnauba wax finish that is food-safe and made specifically for cutting boards.
