How do you keep YOUR grill grates from rusting over and your food from sticking?


I have tried a dozen different methods to prevent rust. Just cleaning it after every use with some grill cleaner then wire brushing alone before using again seems to keep the rust to a minimum at best on my original top grate which i believe is stainless, my bottom grate is the replacement flat one from Menards and that one doesn't rust yet but the black coating is quickly disappearing. My food sticks terribly to both grates no matter how much Pam I spray on them.
What do you do for your grill? What's that one thing you do different that makes your neighbor pissed when he is out buying a new grate?

At this point I'm thinking a good high speed drill w/ wire brush and then rubbing it with lard or some kinda congealed fat.   OOooooooohhh. I just had an AWESOME idea, I'm gonna go rub it down with my used bacon grease then maybe a warm water rinse so there's not enough to burst into flames later.

Believe it or not I have never had a problem with rust. But then as gross as it might seam, I have never cleaned the grill at least not in the traditional way. My Webber kettle is over 20 years old. After everything is cooked I just close the air vents and let the fire die out. Yes it has stuck on meat on it, mostly charred. Then when I set up for the next BBQ after putting the new charcoal in the bottom I put the grill on top, poor charcoal lighter over all of it and let it burn clean. Scrape the char off with a spatula and its good to go for the next time. Since the metal gets very hot anything like bacteria is long gone. Its really not as bad as it sounds. In between uses the oil and fat from cooking keeps the metal coated so it doesn't rust. Sometimes being too clean is not a good thing.

i did that back when i was just using a kettle charcoal type, but my gas one has been trouble from the beginning
I never thought of it before but one of the byproducts of propane combustion is water vapor. It could be some of the rust is coming from the steam put off from the propane flame.

A product of combustion for any hydrocarbon (wood, gasoline, diesel, crude oil, propane, etc.) is water. Since water contains oxygen it allows the iron to oxidize into iron oxide (rust). Also heat will always accelerate oxidation! So the metal that is in or close to the fire will rust first. The best way to prevent the surface from rusting is to put a barrier between the metal and the surrounding atmosphere. See if there is something you could coat the grill in to prevent the rust from occurring.
