What is the best way to clean a wooden kitchen butcher block?

There are two ways: Spray bleach on it and it let it sit for 10

• 15 minutes and wash with warm water. Be sure you rinse it off

well. A solution of Witch Hazel (can be bought at a drug store) and a few drops of "Dawn dish soap" (cuts grease) and that will liven up your butcher block (do the counters while you're at it. Another answer: Use a palm sander with 60 grit, then 150 grit, then 220 grit, when smooth again, wipe surface with vegetable oil or peanut oil, wipe off excess. voila, brand new board.
