Straight white vinegar works well. It is commonly used in the restoration of cast iron pans. Submerge the items for 24--48 hours and rust is gone. You might have to take a stainless steel scouring pad and change out the vinegar if the item is really rusted bad.
Dish Soap -- Even the revered cast-iron manufacturer Lodge says using soap is okay! The trick is to not use any abrasive cleaners here -- keep the Bon Ami/Caulmet/abrasive powders and steel wool or metal scrapers on the no-no list.
You should absolutely clean cast iron cookware. Just don't use anything abrasive like steel wool. Also don't soak for very long. And use a standard dish detergent like Dawn. The notion of not cleaning is decades outdated and comes from when soaps were lye-based (lye will break down the seasoning).

Will Soap Ruin Cast Iron? Using soap will not ruin your pan. It is totally fine on enameled cast iron, and on plain cast iron, too. It's not going to destroy your seasoning.
Common cooking oils like olive oil will gradually produce seasoning, but won't be as effective as grapeseed oil. Canola, other vegetable oils, and shortening are a little better.
For a small amount of rust, just scour it with a scrubber and water like normal and rub with oil. But if you've got a bigger problem, luckily, a little white vinegar and elbow grease are usually enough to whip that pan back into shape.
WD-40 can be used to remove rust from your cast-iron stovetop depending on how much you use and how long you leave it there. If you want to get rid of it quickly, you can try adding more WD-40 or applying the same layer over again.
The simplest way to remove a lot of rust from cast iron is to make a slurry of Bar Keepers Friend and a couple of tablespoons of water in the pan and scrub the rust off using a stainless steel scrubber. We recommend wearing rubber gloves. Again, wash, dry, and re-season your pan afterward.
Cooking with a cast iron pan that has a little bit of surface rust on it isn't likely to hurt you. If your pan is seriously rusty or has visible rust flakes, you shouldn't cook with it until the rust is removed and the pan is washed and re-seasoned.
Add hot water: Wash the skillet by hand using hot water and a sponge or stiff brush (here's our favorite brush, which is designed specifically for cast-iron).

Petrolatum forms a sealing barrier effective against water. This means you can effectively hinder rust if you coat clean metallic surfaces with an even layer of petroleum jelly before placing them outdoors or after use in moist areas.
