I find that the only thing that will clean the gray grates is oven
cleaner.
I put them in a garbage bag, spray with heavy duty oven cleaner (yellow
can), and let them sit all night. I find that the odorless oven cleaner
in
the blue can doesn't work well. You can generally just rinse them off
in
the morning.

Thank you for the cleaning tip. I will give that a try.

I have done this about once a month for the last 6 years. It makes them
look like new. If they have a big build-up on them you might have to do this
a couple of times to get them perfectly clean. After that you can maintain
them with a periodic cleaning. I also use oven cleaner on the drip pans at
the same time.
