Cast-iron pots and pans

Cast-iron pots are ideal for cooking because they conduct heat evenly. They can also be passed down from generation to generation: When properly seasoned, a cast-iron pot will not rust. If a cast-iron pot has not been properly seasoned, however, or it has gone unused for a period of time, rust will form. Removing this rust from your cast-iron pot and then seasoning it can easily turn a rusty pot into your favorite pot.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

Vinegar
Water
Scrub brush
Sandpaper
Towels
Vegetable oil
Aluminum foil
Cookie sheet

Step 1

Fill your sink with a solution of 1 part white vinegar to 1 part water. Immerse your cast-iron pot in the solution.
Step 2

Allow the pot to soak for up to 4 hours. Do not over-soak.
Step 3

Remove the pot from the solution and rinse. With a nylon scrub brush, scrub the pot in a circular motion to remove any loose rust that remains. Dry with a towel.
Step 4

Inspect the pot for signs of rust and lightly sandpaper any traces of it.
Step 5

Heat your oven to 350 degrees F. Lightly coat your entire pot with vegetable oil or shortening. Place a cookie sheet lined with foil on the bottom rack of your oven. Place the pot upside down on the middle rack and leave it in the oven for 45 minutes. Remove, let cool, and store.

Tips & Warnings

Store cast-iron pots without the lids to prevent rusting. Always dry immediately after washing. After washing, place the pot on low heat and lightly coat it with vegetable oil. This will maintain proper seasoning. Steel wool can be used to remove rust from cast-iron pots. Soaking the rust stains in cola can remove them from cast-iron pots.
Do not put cast iron in the dishwasher. Do not store food in your cast-iron pot.
