Just got a lovely heavy maple butcher block cart for the kitchen. Care instructions that came with it suggested mineral or lemon oil to maintain the wood surface. But the lemon oil we bought, intended for wood care, says that it's harmful if swallowed, so concerned about using it for a chopping block. Maybe the potential transfer to any food product is so minimal it's not a concern?
Curious what oils/treatments others use for heavy-duty wood blocks in the kitchen.
