Cast iron, especially cast iron cookware is often handed down from generation to generation because it’s very durable. However every now and then, if cast iron hasn’t been treated or looked after properly, it can develop rust. There are all sorts of tips that casting iron manufacturers can give when it comes to removing rust, but the following is the most popular and most effective one.
Removal of Rust
Depending on the severity of the rust you can try a few different things. First of all try using a potato as your scouring pad. Apply some oil or even some cleanser and rub the oil or cleanser around the pan. You want to make sure the potato responds by rubbing off the rust, so if the potato becomes smooth and slick, which will inevitably happen, just slice this layer off and carry on. If this doesn’t work, you can try using a scouring pad or steel wool. Again apply some oil and scrub away the rust from the surface. Again if this doesn’t work, you can also apply a solution recommended by casting iron supplier with white vinegar and water to the surface, and leave for a few hours. This should be used for serious cases, as the vinegar causes a chemical reaction which can help remove the rust. After the pan has been soaking in the vinegar solution for a couple of hours, simply scrub off with a scouring pad or steel wool.
Seasoning
Cast iron is susceptible to rusting; this is because of its relatively high carbon content. Therefore, you need to make sure that you treat the cast iron to prevent the rust from happening again. To do this you must firstly wash the cast iron thoroughly, using very hot water (the hotter the better) and a small amount of washing up liquid. Wipe the surfaces clean and dry thoroughly. Now you can start the seasoning process. As mentioned this is to treat the cast iron so that it doesn’t rust or corrode. The seasoning is oil or grease that seeps into the pores and crevices of cast iron cookware. Not only does this help prevent rust, but it also gives the cast iron pan a non-stick layer. To season, simply apply oil or grease to the cooking surface of the cast iron cookware. Place in a preheated oven (170 degree Celsius) upside down on the top shelf for an hour. You will need to place a cooking tray on the bottom shelf to catch the drips. Once the hour has passed, take out and place on the side to cool. Once your cast iron has cooled, you can place it in storage, making sure the cupboard is completely dry and way from any kind of moisture.
