Cast iron hobs are a popular choice for cooking enthusiasts due to their excellent heat retention and even cooking capabilities. However, when it comes to cleaning, there’s often confusion about whether a cast iron hob can go in the dishwasher. In this comprehensive guide, we’ll dive into the dos and don’ts of cleaning cast iron hobs and provide you with essential tips to keep your hob in top-notch condition.

Understanding Cast Iron Hobs

Before we delve into the cleaning aspects, let’s understand why cast iron hobs are so beloved in the culinary world. Cast iron is a durable and robust material that distributes heat evenly, preventing hot spots and ensuring your food cooks to perfection. This heat retention also means your dishes stay warm for longer, allowing you to serve your meals at just the right temperature. The seasoned surface of a cast iron hob provides natural non-stick properties, reducing the need for excessive oil and making it an ideal choice for healthier cooking.

With its numerous advantages, cast iron hobs are a favorite for both professional chefs and home cooks. Now, let’s address the all-important question about cleaning.

Can You Put a Cast Iron Hob in the Dishwasher?

No, you should not put a cast iron hob in the dishwasher. Unlike some other cookware materials, cast iron is not dishwasher safe. The high temperatures, powerful jets, and harsh detergents used in dishwashers can damage the seasoning of the cast iron surface, leading to rust and diminished cooking performance. Dishwashers can also strip away the natural oils that create the non-stick properties of a well-seasoned cast iron hob.

Dos and Don’ts of Cleaning a Cast Iron Hob

To keep your cast iron hob in excellent condition, follow these dos and don’ts for cleaning:


  1. Hand Wash Only: The best way to clean a cast iron hob is by hand. Use warm water and a gentle scrub brush or sponge to remove any food residue. Avoid using harsh abrasives that can scratch the seasoned surface.
  2. Use Mild Soap Sparingly: While soap is generally not recommended for cast iron, you can use a small amount of mild soap if necessary. However, make sure to rinse thoroughly to avoid any soap residue.
  3. Dry Immediately: After washing, dry the cast iron hob immediately with a clean cloth or paper towel. Water can lead to rusting, so it’s crucial to keep the hob dry at all times.
  4. Re-Season as Needed: Over time, the seasoning on a cast iron hob may wear off. If you notice any signs of rust or loss of non-stick properties, re-season the hob by applying a thin layer of vegetable oil and baking it in the oven.


  1. Avoid Harsh Scrubbers: Metal scouring pads and abrasive cleaners can damage the seasoned surface of the cast iron hob. Stick to gentle scrub brushes or sponges to preserve the seasoning.
  2. Say No to Dishwashers: Never attempt to clean your cast iron hob in the dishwasher. The dishwasher’s intense heat and powerful jets can ruin the seasoning and lead to rust.
  3. Don’t Soak in Water: Avoid soaking the cast iron hob in water for extended periods. Prolonged exposure to water can cause rusting.
  4. No Air Drying: Never air dry a cast iron hob after washing. Dry it immediately with a cloth or paper towel to prevent rust formation.

With these simple cleaning tips, you can maintain the longevity and performance of your beloved cast iron hob.


Cast iron hobs are a fantastic addition to any kitchen, providing excellent cooking capabilities and versatile use. However, when it comes to cleaning, remember to keep the dishwasher at bay. Hand washing with warm water and mild soap, followed by immediate drying, is the key to preserving the seasoned surface and ensuring your cast iron hob remains in top-notch condition for years to come.
