Wood has natural antibiotic qualities that result in a chopping board that, if cared for properly, will host far fewer bacteria than a plastic alternative, and won’t produce micro-plastics when scratched. For tougher cleans, a bicarbonate of soda slurry can be used with a gentle sponge — such as a loofah — or natural fibre brush to work out tough stains. When washing, using hot soapy water, both sides should be wetted and rubbed, even if only one has been used, so as to prevent un-even drying. If the board has absorbed some strong smells like garlic or onion, a layer of fine salt and lemon can be spread across the surface and left to absorb before being scraped away. This will deodorise the board without the use of heavy chemicals. Wooden chopping boards will last longer and function better with regular conditioning. Neutral oils can be rubbed with a clean cloth into the board, and then sealed with beeswax. When you first buy a board, you should oil it quite regularly for a few weeks until it stabilises. Thereafter oil every few weeks, treating it much like a plant and feeding it whenever it looks thirsty.
Using a wood conditioner on a chopping board not only enhances the boards appearance, but also seals the surface, locks in hydration, and protects the wood from moisture and bacteria. Beeswax and other natural waxes create a surface layer that keeps water, juices, and food liquids out. The thick wax helps fill in minor scratches and grooves made by knife blades, restoring a smooth surface to the wood. Sealing the pores prevents food particles, stains, and bad odours from sinking into the wood and breeding bacteria or mould.
