I don't use one. I simply crank the heat up to 600+ for a few minutes after grilling, and then wipe it with a blue scrub sponge once it cools. Everything simply wipes off and is ready for next time.
No brush. Heat up the grates and scrub lightly with a wad of aluminum foil. Works like a charm.
Once a year I pull all my grates from the grills and smokers, put them in a black trash bag when it's 90+ outside and douse them with oven cleaner. Tie up the bag and let it sit for 4-5 hours letting mother nature handle the heat. They come out spotless.
I like keeping them clean and heat doesn't cut it with me - certainly not "spotless" and the residue does promote sticking and hot spots on the food - like cheap cookware makes hot spots in a pan.
The drill I have is a bottle of olive oil by/under the grill. Wet a paper towel and wipe the grates before cooking. As food comes off, run them over quickly with any old grill brush. Clean and fresh for next time.

Ahhh... the old Bundy Burger method:

Mine uses a stainless steel scrubby held in place with two pins. The thing lasts for years. Don't remember the name though. Replacement scrubbies are available.
Doesn't rust, works better than a brush at cleaning and lasts a long, long time.
