20 minutes to scrub out a new wok with a harsh cleanser, dry it and heat a coating of oil slowly until just to the smoking point, then wipe out with paper towels and hang up.
And this "no washing" is a bunch of bull. Asian Eths probably don't wash because they haven't traditionally had decent washing facilities. I always wash, in fact I wash mine every time it's used, with institutional grade cleanser, then warm it on the stove, put in a dash of olive oil and wipe it around with a paper towel just to coat. Hang it up.
