I have no dishwasher (or rather, that'll be me). I inherited my pan 20 years ago; it ws in poor shape. I stripped it with caustic soda, and re-seasoned it, which took about a day elapsed. Ever since, it gets washed-up using detergent, and immediately dried. It's as good as when I first seasoned it. I've never had to repair the finish.
