How To Eliminate Rust With Ketchup
First, assess the extent of rust on your cast iron pan. Ensure the pan is dry before applying ketchup. Next, generously apply a layer of ketchup over the rusted areas of the cast iron pan. Use a spoon or brush to spread the ketchup evenly, ensuring that all rusty spots are covered. After applying the ketchup, allow the pan to sit for a few hours to allow the acids in the ketchup to work on the rust. The exact duration may vary depending on the severity of the rust, but leaving it for at least an hour is recommended. For stubborn rust spots, you may need to leave the ketchup on overnight.
