Though nearly twice as expensive as lemon oil, John Boos Mystery oil is worth every penny. I originally bought it to condition the oak staves on my wine presses, but have since discovered that it works equally well on the kitchen and dining-room tables (both oak). I even put it to work on pine wainscoting, cedar panelling and cherry furniture. It's virtually effortless to apply; it immediately penetrates the wooden surfaces, so it dries quickly with very little need to wipe off excess oil; and it makes everything look beautiful. I'll never use anything else
