Thanks. All your responses are worth consideration. As I said originally, the scrub plane did the job but I would not to use that on wider stock. I had previously tried soapy water and a wire brush but could still feel a lot of grit on the surfaces. The pressure washer will be tried on the next batch.
Wouldn't you know it, after all the preparation, the piece bowed when I resawed it across its width. Won't be making any cabinets with that stock. Will have to use it making boxes and other small pieces. The sapele grain and color are wonderful. Just need to downsize expectations, again.
Rustic? Well, no. That was not my intention!
