John Boos Mystery Oil is used to keep your butcher block or cutting board looking new. The food safe oil is a mixture of mineral oil, linseed oil, and tung oil. Using the Mystery Oil will help to give you the same quality finish on your wooden tops or blocks as its original, factory finish. John Boos recommends oiling your wooden items every 4-6 weeks.
