Keep your wooden cutting boards and butcher blocks in prime condition with John Boos Block Mystery Oil. Once a month, apply an even coat of NSF Approved John Boos Mystery Oil to your cutting board or butcher block and allow it to soak in overnight. Allow the Mystery oil to fully penetrate through the wood fibers overnight, then wipe off any excess oil. Apply additional oil to any visible dry spots or for any other necessary reasons. Do not over oil your cutting board. Repeat this process more often when the board is brand new and thirsty, or if you live in a dry, arid climate. John Boos recommends applying John Boos Board Cream (sold separately) to seal the top of the wood surface after applying the Mystery Oil. A few quick minutes of regular oil application will ensure your new board is properly seasoned, and ready for work! Applied every three to four weeks, John Boos Mystery Oil prevents wood from drying, splitting, or cracking. Mystery Oil is safe for food preparation surfaces and can also be used to maintain wood countertops and wooden kitchen tools. Proudly Made in the USA of all Natural ingredients. NSF certified.
