In the rare instance I get a NEW unused cast iron pan (I look for them at estate sales used) I heat it hot, let it cool and rub some EVO on it everywhere. Then let it rest so the pores can absorb the EVO. After every use I wash in a sink of hot soapy water (I was taught Food Safety and Sanitation as part of my culinary training at the California Culinary Academy), dry the pan with a towel and then heat until hot and then once the pores have vented rub in some EVO. I do this again and again. I believe it takes more than a wisk or scrub with a wire pad to CLEAN a pan. I must have over 15 cast iron pans and pots (from very small to VERY large, fry pans, dutch ovens, Descoware). I love them, I don't usually use anything but cast iron to cook in.
