I have SS grates on my Genesis and they are well used by me and the previous owner. One thing I've noticed that while they are dull from heat, etc., I end up with black on them after doing burgers, etc. I always run the grill full throttle for about 15 minutes after grilling before shutdown. Before the next cook, I use a wire brush to get off the loose stuff. I have a Chargon tool as well, but the black always seems to remain. The dishwasher has not removed the black, nor has oven cleaner. Any thoughts? The grates seem smooth and being dull is no issue for me.
