How to clean your carbon steel pan
Similar to cast iron, you don't want to put your carbon steel pan in the dishwasher or use soap on it as this will strip the oils in your seasoning. Instead, use coarse salt and a rag or boil some water in the pan to free more stubborn stuck-on food.
All you need to do to clean your carbon steel pan is to wipe out any excess oil from your pan, using coarse salt to free any stuck-on food. This will keep your pan’s seasoning intact. If there are pieces of food stuck to your pan, add a tiny bit of water to cover the bottom of your pan and bring the water to a boil over medium heat. Once the water reaches a boil, scrape at the food bits with a wooden or rubber spatula. Once your food is no longer stuck, dump out the water, and dry your pan thoroughly. Return your pan to the stovetop and heat it over medium-low to get rid of any excess moisture. Add a very thin layer of high smoke point oil or Made In wax to the pan, and spread the oil using a paper towel or dish towel all over the pan until it is evenly coated. Your pan is now clean and seasoned!
We have a post that outlines cleaning steps to ensure you maintain that seasoning here as well.
