Cast iron cookware is recognized for its even heat distribution, versatility and long-lasting durability, but it is porous and prone to stains. Exposure to minerals in hard water can cause calcium deposits to accumulate on cast iron pans. While calcium deposits do not structurally damage cast iron, they can make cleaning less effective. The longer calcium deposits remain on cast iron, the more difficult they are to remove. Fortunately, basic solutions can effectively remove white calcium deposits from cast iron pans.
Step 1
Scrub the pan with a nylon scouring pad to remove loosened mineral deposits and grime. Thoroughly rinse the pan with warm water.

Fill a plastic bowl with 1/2 cup of baking soda. Add 1/2 cup of white vinegar to the baking soda. Thoroughly mix the ingredients with a spoon.
Step 3
Spread the mixture directly over the calcium deposits. Keep the mixture on the calcium deposits for at least 30 minutes.
Step 4
Scrub the calcium deposits with the scouring pad until the white scale is completely removed.
Step 5
Rinse the pan with warm water to wash away the loosened calcium deposits and baking soda mixture.
Step 6
Dry the pan with a clean terry cloth towel. Repeat the cleaning process if any white deposits remain on the cast iron.
