What will make your timber cutting board to last the longest is not to let it soak in water, just use warm water and soap to wash it, then dry it off right away. When you notice the board becoming lighter in colour, give it a wipe with sunflower oil or processed coconut oil. Unprocessed coconut oil will leave a flavour on the food. Do not use olive oil - it becomes rancid. All of our wooden cutting boards come delivered with a food safe and waterproof organic tung oil coating. This coating is self healing from cuts, and the underlying timbers are naturally antimicrobial. This is why wood is still the preferred cutting board material. If you’d really want to treat your cutting boards and your nose, then use Gilly's food safe waxes. They smell amazing, and contain natural Carnauba and Bees waxes protecting your timber while making it look fantastic. All of their products smell incredible. I believe you might be able to get a tin from Bunnings, some kitchen stores, or even order direct from Gilly's themselves. They are in Western Australia. Great bunch of people to deal with, and really great smelling waxes! Mineral oil works well and is food safe, but it’s not a permanent coating. I personally haven’t had problems with the occasional coat of sunflower oil, or processed coconut oil if that is all you have available in your kitchen, but for a permanent food safe coat, you can’t beat tung oil which will harden and waterproof the chopping board.
