Yes, you can use soap on cast iron. Despite the common belief that soap will ruin your seasoning, a gentle soap can safely be used to clean a properly seasoned cast iron skillet. The key is knowing what kind of soap to use and how to wash your skillet without leaving it wet or soaking it for too long.
Does Soap Remove Cast Iron Seasoning?
No. Using a gentle soap on a properly seasoned cast iron skillet will not ruin the seasoning. The idea that soap and cast iron don't mix is an outdated myth. A gentle Castile soap can help remove food, grease and residue without stripping away your skillet's seasoning. Of course, harsh cleaners, excessive scrubbing and prolonged soaking should still be avoided.
What Soap Should You Use on Cast Iron?
A gentle, cast-iron-friendly soap is best for regular cleaning. You don't need a harsh detergent to remove food, grease and odors. Caron & Doucet Cast Iron Soap is a gentle Castile soap made with plant-based oils and formulated specifically for cleaning cast iron cookware. It's made without sulfates, phosphates, parabens or petrochemicals, helping clean your skillet without being unnecessarily harsh on the seasoning. It's especially useful after cooking foods that leave behind grease, stuck-on residue or strong odors.
How to Clean Cast Iron With Soap
Cleaning your skillet is simple:
1. Add warm water and a small amount of soap. There's no need to fill the skillet or let it soak.
2. Scrub away food residue. Use a sponge, cloth or a cast iron scrub, such as the Caron & Doucet Cast Iron Scrub, to loosen stuck-on food.
3. Rinse thoroughly. Make sure all food and soap residue is removed.
4. Dry completely. Towel dry your skillet and, if needed, place it over low heat to remove any remaining moisture.
5. Add a thin layer of oil. Once dry, apply a very thin layer of Caron & Doucet Cast Iron Oil if your skillet needs it.
What Should You Avoid When Cleaning Cast Iron?
While soap is fine, there are a few things you should avoid:
· Don't soak your skillet. Prolonged exposure to water can lead to rust.
· Don't leave it wet. Always dry cast iron thoroughly after washing.
· Don't use harsh cleaners. A gentle soap is all you need for everyday cleaning.
· Don't overdo the scrubbing. Start with a gentle approach and increase the scrubbing only when necessary.
