Yep, John Boos is a stateside wood counter top maker and recommends it for all of their products including the high end stuff.
Can't remember the schedule right now but it goes something like once a day for a week, once a week for a month, once a month for a year and then as needed. The nice thing is it never gets sticky, provides some level of protection (not as much as a drying oil/plastic but they have their own issues) and is easily renewable.
