The Stainless Steel Grills have a smooth surface that is easy to clean and maintain. Over time, however, it can discolor from heat or if it's not properly cared for. Stainless steel grills are more resistant to corrosion and will last longer with proper care.  No matter what kind of grill you have, proper care is essential to keeping it in good condition. Be sure to clean your grill after each use, and perform a deep clean at least once a month. Inspect your grill regularly for any damage or wear, and make sure to replace parts as needed. With proper care, your grill will last for many years to come.
