Its taken Grumpy years to formulate, what he believes is the ultimate cutting board conditioner. He has used all of the major brands and a few of the new popular ones that are out there. In his opinion, they all miss the mark. None of them add essential oils, vitamins, and minerals. Every carpenter who is worth his weight in salt will tell you wood is a living breathing thing. If it’s living and breathing why are none of the conditioners feeding the wood? That is what he set out to do and he has accomplished that. It’s the reason he can offer a one-year warranty if you use Grumpy’s Love Butter.
