Hi everyone, I came here to see if there is any recovery for these grates. My boyfriend bought me a new grill (early Christmas) and it was delivered by Home Depot in this condition. Before contacting their support I do try to clean the grates with some cleaner I typically use for my other grill (same brand). However I had no luck and the grates still look the same.

Otherwise we have to have them pick this one up and wait for another delivery, and hope those grates are not rusted.
