If properly maintained, your Big Green Egg and its components will last a lifetime. The Spiral Grid Cleaner will help you keep the grid in perfect condition. The 2 spiral-shaped brushes are perfect for thoroughly cleaning the porcelain-coated, stainless steel and cast iron grids. Without a scratch. We probably all agree that cleaning isn’t the nicest part of EGGing, but it is a necessary chore. We’ve tried to make it as easy as possible for you with the Spiral Grid Cleaner. As it consists of 2 spiral brushes, you are basically brushing in stereo. Which makes it go twice as fast.
