Cast iron grill grates are a beloved staple in the grilling world, offering unparalleled heat retention and durability. However, maintaining their pristine condition requires proper care and attention. This comprehensive guide will equip you with the essential knowledge and techniques to keep your cast iron grill grates in optimal shape for years to come.
