The usual cause of rusted cast iron grates is that they're too clean.
Seasoning is essentially a layer of carbon which is thick enough to be
waterproof.
Brushing before cooking is how I do it, too-as the grill is heating up
(3-400F range).
Spraying oil onto the brush is also a way to apply it to the grill.
