bucher block oil:

people are always asking me how to take care of their cutting boards and butcher blocks and other wooden kitchen utensils. 
therefore i have now made my own concoction you can purchase at shows etc made out of food safe mineral oil for conditioning and cosmetic grade beeswax for protection.
simply rub your boards, salad hands, spreaders etc down with this conditioner. 
the mineral oil will penetrate and hydrate the wood and the beeswax will harden on the surface and make it a wee bit more water-resistant. 
polish it a little to get excess wax off and give that wood some gorgeous shine.
