The smaller woks I heat cycled with safeway branded toasted sesame oil. Smelt alright but seems to have left a strange coating on my bamboo brush and rubber gloves. The are not that non stick, but then I use a metal scraper while cooking so non stick doesn't really matter. Will get better with use and then gets washed with boiling water and the bamboo brush.
The 12inch I have heat cycled three times with table salt, the pan has heat marks but no idea as I haven't used it yet.
