Several factors can cause rust to form on your cast iron Dutch oven:
- Exposure to water and humidity

Step-by-Step Guide to Removing Rust
Gather Your Supplies
Before you start, you will need the following:
- Steel wool or a stiff brush
- White vinegar
- Baking soda
- Dish soap
- Clean cloths
- Vegetable oil or shortening
Step 1: Scrub Away the Rust
Use steel wool or a stiff brush to scrub away as much rust as possible. Be thorough, but dont worry if you cant get it all in one go.
Step 2: Soak in Vinegar Solution
Soak the Dutch oven in a solution of equal parts white vinegar and water for no more than one hour. This will help to loosen the remaining rust.
Step 3: Scrub Again
After soaking, use the steel wool or brush to scrub the remaining rust. Rinse the Dutch oven thoroughly with warm water.
Step 4: Apply Baking Soda
Baking soda can neutralize the acidity of the vinegar and prevent further rusting. Sprinkle baking soda onto the wet Dutch oven and scrub with a brush. Rinse well.
Step 5: Wash with Dish Soap
Wash the Dutch oven with dish soap and warm water, then rinse and dry completely.
Step 6: Re-season the Dutch Oven
Seasoning is the process of creating a protective layer of oil on the cookware. Heres how to do it:
- Heat your oven to 350F (175C)
- Apply a thin layer of vegetable oil or shortening to the entire surface of the Dutch oven
- Place it upside down in the oven on the middle rack (place a sheet of aluminum foil on the lower rack to catch drips)
- Bake for one hour, then let it cool in the oven

Regular seasoning creates a protective barrier that helps prevent rust. After each use, apply a thin coat of oil to the surface.
