Frequently Asked Questions

How often should I season my cast iron skillet? expand_more
Season your skillet whenever you notice the coating becoming dull or food starting to stick. With regular use, this might be every 3-6 months. However, proper cleaning and maintenance between uses can extend the time between seasonings.
Can I wash cast iron with soap and water? expand_more
While traditional wisdom says never use soap, modern dish soap is mild enough for occasional use, especially for heavily soiled pans. However, hot water and a stiff brush are usually sufficient. Always dry thoroughly and apply a light coat of oil after washing.
What's the best way to remove rust from a cast iron skillet? expand_more
For light rust, scrub with steel wool or a wire brush, then immediately re-season. For heavy rust, soak in equal parts white vinegar and water for up to 8 hours, scrub clean, rinse thoroughly, dry completely, and re-season multiple times.
Is pre-seasoned cast iron truly ready to use? expand_more
While pre-seasoned skillets are technically ready to use, adding 1-2 additional seasoning layers before first use will improve the non-stick properties and provide better protection against rust.
Can I use metal utensils on cast iron? expand_more
Yes, cast iron is durable enough for metal utensils. Unlike non-stick coatings, the seasoning can withstand metal tools and will actually improve with use. However, avoid dragging or scraping aggressively to maintain the seasoning.
What's the difference between cast iron and carbon steel skillets? expand_more
Cast iron is thicker and retains heat better but heats more slowly and unevenly. Carbon steel is lighter, heats more evenly, and develops non-stick properties faster, but doesn't retain heat as well. Both require seasoning and can last generations with proper care.
