I've only once used a humidity box. I find that rusting twice per day, with a boil in the morning before leaving for work and once in the evening after dinner, perfectly fits my schedule and produces excellent results, perhaps owing to the mantra of damascus's Birmingham barrel finisher. In any event, this works for me, and in a week I'm done. Pretty easy.
