I'm very leery of claims that you can simply use hot water and wipe clean. While I realize "they" have done it this way forever, "they" also used to make a poultice of chicken poo for sprains.
My CI is cleaned with hot water, soap, and a plastic scrubber followed by a thorough drying and a wipe with oil. According to Cooks Illustrated even a run through a commercial dishwasher didn't affect a properly seasoned pan.
Here's an article on the science of seasoning with
Flaxseed oil. There's been a slew of posts to various forums disputing the chemical changes this author describes but the process itself is not questioned. I'm going to guess the type of oil isn't as important as the process used.
Heat your CI to 200 and wipe with oil.
Using a clean towel, remove all the oil you can.
When you think you've gotten all the oil off,
wipe it one more time.
Bake at 450-500 for one hour a let it cool slowly with the oven door closed.
Repeat a minimum of 6 times.
I tried speeding up the process by using a heavier coat of oil and the resulting splotches required a brass scouring pad and a
lot of scrubbing to remove. I had to work pretty hard to remove that one layer. There's no way a little soap and plastic scouring pad is going to hurt this pan.
