A little rusty carbon steel or cast iron pan can't hurt. You can still cook with it just fine, it won't make you ill. Don't have a Skottsberg, but a pan with a synthetic non-stick coating in which rust has formed? Throw that pan away then.
According to the US Environmental Protection Agency (EPA), ingesting rust in small amounts will not harm your health (unless you have a rare disease called hemochromatosis, which causes your internal organs to retain iron).
Yes. A little rust won't hurt you. Of course food will stick rather badly to a rusty surface. So, you might want to clean and season the surface before using it.
In summary - A small amount of light exterior rust is usually fine to cook with after removal. But heavy, flaking, or pitting rust indicates more serious issues and potentially damage to the pan surface that could affect cooking. It's best to remove rust when possible for longest pan life.
Cast iron can be pretty resilient, and even very rusty, damaged pans can be rehabilitated—and in most cases, the rust they're facing is pretty minor. It's important to note that you shouldn't use your skillet while it still has rust on it.
It's not particularly safe, but the hazards posed by rusty pans vary in terms of severity. Rust is not a food-safe material and shouldn't be ingested, but you may not be exposed to it depending on what you're baking.
Moisture is the enemy of cast iron, making storage conditions pivotal in preventing rust. Ensure your cast iron cookware is completely dry before storing it. Some enthusiasts recommend placing a paper towel inside the cookware to absorb any residual moisture and leaving lids ajar to allow air circulation.
Since olive oil is such a pantry staple, many people naturally wonder if they can use olive oil to season cast iron. You can use olive oil to season cast iron, but you need to choose a high quality extra virgin olive oil, which should have a smoke point close to 400 degrees Fahrenheit.
But this is an important Woks of Life PSA: Carbon steel and cast iron woks can last a lifetime (or multiple lifetimes—we have woks that are decades old—they can be passed down to the next generation). They CAN be revived if rusty. If you have a carbon steel or cast iron wok that's rusted, don't throw it away!
TOP TIP: A combination of baking soda and vinegar can be effective for rust removal. The reaction between baking soda and vinegar produces a gentle fizzing action that helps lift rust from the pan's surface. Apply the mixture to the rusted areas and let it sit for a few minutes before scrubbing.

Oil, especially canola oil (bad, unhealthy oil), should not be used. If a quick oiling (not seasoning) in between is desired, it's best to use a high temperature oil like avocado. A quick rub can do the trick, if your pan looks a bit dry. I have one pan that is about 100 years old!
If you just purchased a new cast-iron pan, you may want to repeat the oiling and heating process one to two more times before you use it for cooking. Even when labeled pre-seasoned, new pans can benefit from the additional protective layers.
If you're planning to throw away your pan just because of a little rust, well, don't. Unless your pan has completely rusted through (which is extremely unlikely) or somehow cracked in half, there's no reason to discard it. Rust development happens to everyone's cast-iron pan from time to time, even to us.
Only iron can rust. That means other metals that do not contain iron are not susceptible to rusting. This makes them ideal for outdoor placement, as they'll last much longer in natural conditions. Learn about which metals don't rust, as well as which metals do rust.
Rust is not a food safe material so it should not be ingested. If you see rust on the surface of a utensil such as a cast-iron skillet or knife, remove all the rust before using it.
