Hard anodized aluminum is a process of applying a layer of aluminum oxide to the surface of aluminum, which makes it extremely durable and resistant to wear. This layer also protects food from bare aluminum, which is important for cooking equipment.
Despite the durability of hard anodized aluminum, it can still wear over time. To help maintain the integrity of your Jetboil or other hard anodized aluminum cooking equipment, we recommend using non-metallic utensils and low-abrasion scrubbies during cleaning. Additionally, when packing a Jetpower canister inside the cooking cup, we advise drying the cup thoroughly and separating the two with a layer of cloth to prevent scratches. Using the fuel cap on the canister also helps minimize wear by keeping the canister and burner base in place within the cooking cup.
