I do mine at home every time I cook on them at home, if outside clean it right after cooking and treat. If you are at home and the bottom needs work, clean it up and simply place on stove, turn your exhaust fan on and get er hot, rub down with oil and paper towel, even if you dont have a fan, smoke will be minor, but very simple to do..every time I use my pans in the house they get rinsed with hot water and scrubby, then dried on the stove...even if used every night this is how to dry them, no big deal, no project...the dutch oven gets the same treatment... I bought an old one that was extremly crusty, I took up to my shop and placed in the shot blaster using stainless shot. Brought it home and used cleanser and a scrubby..worked the pan over and smoothend the cooking surface, placed on stove and heated with oil and it has been great...
Tip:::once the pan starts to give off smoke, turn the burner off..works great
