Fixing rust on a vintage Griswold cast iron skillet requires careful cleaning and re-seasoning to restore its cooking surface and prevent further corrosion. Here's a step-by-step guide to help you remove rust and bring back the skillet's functionality:
Materials you'll need:
- Steel wool or a wire brush (make sure it's not too abrasive)
- Mild dish soap
- Water
- White vinegar or lemon juice
- Baking soda
- Clean towels or paper towels
- Vegetable oil or flaxseed oil (for re-seasoning)
Step-by-step process:
Safety first: Work in a well-ventilated area and wear gloves and safety goggles to protect your hands and eyes.
Remove any loose rust: Use a steel wool or a wire brush to gently scrub the skillet's surface and remove any loose rust. Be gentle to avoid damaging the cast iron.
Create a rust-removal solution: Mix equal parts of white vinegar (or lemon juice) and water in a container large enough to submerge the skillet. Alternatively, you can make a paste using baking soda and water.
Soak the skillet: Submerge the skillet in the vinegar-water solution or apply the baking soda paste to the rusted areas. Let it soak for several hours or overnight. This acidic solution will help dissolve the rust.
Scrub again: After soaking, use the steel wool or wire brush again to scrub the rusted areas. You can also use a sponge or scrubber for this step.
Rinse and dry thoroughly: Rinse the skillet thoroughly with water to remove any remaining vinegar, lemon juice, or baking soda. Dry the skillet completely with a towel to prevent further rusting.
Re-season the skillet: Since the rust removal process may have stripped some of the seasoning, it's crucial to re-season the skillet to protect it from future rusting. Apply a thin layer of vegetable oil or flaxseed oil to the entire skillet, inside and out.
Bake the skillet: Place the skillet upside down on the top rack of your oven, with a foil-lined tray or foil underneath to catch any drips. Bake the skillet at around 350-400°F (175-200°C) for about an hour. This process will polymerize the oil and create a new non-stick layer.
Cool and repeat seasoning (optional): Allow the skillet to cool in the oven, and then repeat the seasoning process (applying oil and baking) several times if necessary to build up a strong seasoning layer.
Remember, maintaining the seasoning on your cast iron skillet is essential to prevent rust and maintain its non-stick properties. After each use, clean the skillet with minimal soap, dry it thoroughly, and apply a thin layer of oil before storing it. Regular use and proper care will help keep your vintage Griswold cast iron skillet in excellent condition for many years to come.
