  • Step 1: Wash the pan

For new pans, use warm water to rinse the pan. For used pans, you can use the mentioned above method to clean the cast-iron pan.

Dry the pan completely by boiling the pan on the stove or drying it in an oven to ensure the removal of moisture on the pan.

  • Step 3: Cover the cast iron with oil

Add a small spoon of cooking oil to the pan, using a towel to apply the oil to the entire pan (both inside, outside and handle)

* Note: Use cooking oil with a fuming temperature not too high to ensure maximum oil adhesion to the pan surface to create the best natural anti-stick layer. The recommended cooking oils are soybean oil, sunflower oil, and canola oil.

  • Step 4. Dry the pan in the oven for 45 minutes to 1 hour

Put the pan lying face up in the oven. Turn on the oven at 180 – 230 ° C for at least 45 minutes to 1 hour. Then turn off the oven, let the pan cool down in the oven.
