How to deal with new cast aluminum pot before use

For the first time, use an aluminum pan. It is best to cook or hold oily stuff first, so that the oil fills the small recesses on the wall of the pan to increase the antiseptic ability. It should be noted that the new aluminum pan should not be boiled or steamed first. Otherwise, the bottom of the pot will turn black and not look good. However, aluminum pots have been used for a long time, and black spots or white precipitates generally appear in them, which is harmless to the human body and can not be wiped off. If you want to wipe it off, just wash it with a little vinegar or burn it.
