Cleaning
A cast iron pan is best cleaned with a little water and a soft sponge. Do not use a hard sponge or aggressive soap, as this can damage the natural non-stick coating. Is the pan very dirty? Then you can use the Blackwell Cleaning Chain. With this you can remove caked-on food residue without damaging the pan and without cleaning agents.
Sterile cleaning
Another way is to heat the plan briskly with a layer of water. Once it gets above 115 °C, the bacteria will be killed and the pan is sterile. Due to the high temperature, any food residue will loosen from the pan and all you have to do is run a cloth through it or the Blackwell Cleaning Chain.
Thorough cleaning
Should you want to clean the pan even better, you can also put a little salt in the pan and heat it. Preferably larger grains, such as sea salt. Once the pan starts to smell, you can use a cloth or the Blackwell Cleaning Chain to scrub the pan clean with the salt. You will see that the salt becomes discolored. After scrubbing, discard the salt and wash the pan with water. Then put a drop of oil, preferably peanut oil, not olive oil in the pan and wipe it out with a cloth all over the pan.
