How to maintain an iron cast pan – 5 tips to extend its lifespan 

While cleaning may begin with large surface areas – from your floor to your countertops – it's essential not to neglect your cookware. Especially when they're so key to the kitchen. However, there is more to maintaining a iron cast pan than knowing how to keep it clean. Here's what you need to know.  

1. Cook over low heat

One of the most effective ways to maintain an iron cast pan is by cooking on lower heat where possible. Daniel P. Craig, the Founder of Kitchen Deets, explains that this will protect the seasoning in the pan and make the cleaning process easier. 

Once your cast iron gets hot, it is likelier to stay hotter for longer, especially in comparison to another style of pan. So, while it is best to cook at a low temperature, you can still enjoy the heat in your pan for a noticeably long time. 

2. Avoid metal utensils 

Metal utensils are increasingly popular pantry staples, but Daniel warns that these appliances can have a negative impact on your iron cast pan. He urges you to invest in plastic or wooden utensils when cooking, as these metal alternatives will scratch the pan – and leave the cast iron looking unmaintained.  

3. Be cautious of acidic foods

Acidic foods, including certain dairy products and some seafood, can cause long-term damage to your iron-cast pan, so it is important to remove acidic foods from your pans immediately after cooking. 'Wash the pan promptly in hot water so that acidic food doesn't break down the seasoning,' Daniel says.  

4. Avoid leaving food in your pan 

No matter how acidic your food may be, the expert warns that it is problematic to leave any product in your pan for an extended period of time. This can cause your iron cast pan to corrode – meaning it is less efficient and much less likely to last a lifetime.  

5. Leave your pan out of the dishwasher  

There are many surprising items you can clean in the dishwasher, but Daniel warns that your cast iron pan is not one of them. 'The harsh detergent can ruin the seasoning on your pans,' he warns. Instead, you should follow an expert cleaning method, involving oil, that will leave your pan spotless in under an hour. 

'You want to dry the pan with a cloth immediately after washing, rubbing a bit of oil on it before putting it away,' explains Bill Glaser, the CEO of Outstanding Foods.

Should I oil my cast iron pan after every use?

Yes, you should oil a cast iron pan after every use. There’s a process called reseasoning that will bring your cast iron back to form. 'Clean your pan, covering it with the vegetable or canola oil, then place the pan upside down in your oven (with an aluminum foil sheet at the bottom) to bake at 350℉ for one hour. Your cast iron will emerge good as new,' explains Bill Glaser, the CEO of Outstanding Foods.'

So, while washing up can feel tedious, it is worth the extra care when it comes to maintaining an iron cast pan that will continue to serve your needs for years to come. 

What is the best oil to season cast iron?

The best oil to season cast iron is a vegetable oil, though you can use any cooking oil or fat to season cast iron pans. A spray-on oil is the simplest to apply.
