Stainless steel, the material used in the Leaf Razor, is known for its rust resistance. The chromium in stainless steel forms an invisible protective layer that shields the material from water and air, preventing rust. However, under certain conditions, such as exposure to saltwater or harsh chemicals, stainless steel can potentially rust. Therefore, cleaning and drying your Leaf Razor after each use is recommended and storing it in a dry place to maintain its longevity and performance. Remember, while the Leaf Razor is designed to resist rust, the blades, typically made of steel, can rust if left wet for extended periods. So, it's also important to dry the blades after use.
