When cleaning wheels I use a good spoke brush and boars hair brush to agitate after spraying megs wheel brightener on and letting it sit for a minute to penetrate. For a full detailing of wheels I use a hydraulic floor jack from craftsman and take the wheels all the way off using an air ratchet. I clean every inch with my megs and clay all surfaces followed by a good sealant. While the wheel is off I make sure to clean the brakes, suspension components (with any necessary painting done at this step) and I make sure to clean and dress the wheel well. With the wheel off you can do a really good cleaning of the tires with APC and dress the tire without having to worry about missing the unexposed areas underneath.
