Is there a good brush for cleaning custom wheels?

I have custom aluminum spoke wheels and it's tough to get the brake dust and dirt off the backside and between the spokes. Does anyone know of a good brush that would work?Is there a good brush for cleaning custom wheels?

I've never used a brush to clean my rims. There's a chance of them scratching them. I'd use something like Meguiars Wheel Brightener (http://www.meguiars.com/?detailer-wheel-… and use a soft rag to clean them. It might take longer than a brush, but won't scratch up your rims.
NO SUCH THING. IT IS UP TO THE CHEMICAL TO CLEAN IT. OTHERWISE, YOU HAVE TO BUY NEW WHEEL. ONCE THE BRAKE DUST COOKED ON TO THE RIM, IT STAY THERE FOREVER LIKE RUST ON STEEL.
not really just use a towel or wash them
