Cast iron cookware
Here's another kitchen no-no: Don't use steel wool cleaning pads on your cast iron cookware. If you use cast iron a lot, you probably know how important its protective seasoning is, and so does John Bedford, founder and editor of Viva Flavor, a food company that also specializes in cookware maintenance. "Developing and maintaining good seasoning on cast iron cookware is a labor of love," he told RD.com. "An SOS pad is a quick way to undo a lot of hard work, especially if you use soap as well." There are all sorts of other products that can clean your cast iron, so avoid the SOS pad.
He says that the only time it might be okay to use an SOS pad on cast iron is if the pan has rusted. "In that case, I remove the rust as gently and precisely as possible, and then re-season the cookware properly before cooking with it again," he says.
