How do you clean and season a cast iron pot?
First I would highly recommend getting the food out of the pot as soon as its cooked. Letting the food sit in the pot for several days is the main problem. The sooner you clean the pot the better. I would scrape the pot (i use a polycarbonate scraper) to get it clean and then heat the pot on the stove to make sure is dry, then finally add the oil after you're sure the water has evaporated. When you apply another layer of oil it is not exactly seasoning the pot unless you expose the oil and pot to very high heats. I would recommend making sure the pot is clean and seasoned well, then try to follow the cleaning above.
