I use a schmitt, it's a black coarse foam mitt. If you have a lot of streaks and stuff stuck on your wheels, I'm gonna have you use a Heavy Duty Mr. Clean Magic Eraser like a claybar.
1.Heavily concentrate a soap, like CWG, about 2oz. You'll actually only need about a half gallon of water at most, and your rinse bucket of course. Dip the magic eraser in the soap mixture and use it as a lube as you would QD for claybarring. The eraser has an abrasive nature to it, so it will take scuffs and minor stains off just like a polish would on regular paint. Don't use these on regular paint, they will harm it. You should notice a lot of the scuffs and stuff on there being removed. Bend the eraser like a piece of pizza into the lug nut holes as well, they'll become very clean. Try to develop a pattern with each wheel as to not forget a spot.
2.Next you'll want to claybar the wheels, preferably with a piece of clay you already used on the paint for monetary saving purposes. Claybars should be used at follows... Paint --> Glass --> Wheels. This prevents brake dust from going on to paint and as you use it throughout the steps the clearcoat or surface is a lot harder so the contaminants in the bar will affect the surface less.
3.Use an applicator pad to use your Poorboy's SSR (2.5 if you have it) to polish out any imperfections left by the eraser. Even if the hairlines are too deep, the polish will round the edges off and they'll become a lot less noticeable due to the newly reflected angle of light. Use a 50/50 Isopropyl/Water mixture to remove the oils and fillers from the polish after a microfiber wipedown. This will also provide a clean base to prep the surface for a sealant.
4.For maximum protection, use KSG and allow to cure overnight. 12 hours I believe is what Jason said. After the sealant has cured, apply your PBW Wheel Sealant. You'll find your wheels ALOT easier to clean than before, If you buy a pressure washer you'll actually be able to clean them without soap and water.
Should take about an hour or so but it'll be worth it. Definitely will be the cleanest your wheels have ever been.
