Before I switched to a chain wax, I used kerosene and a paint brush to get the worst gunk off, then WD40 and a rag. You can tear an old cotton sheet or just cut up some old towels (remember I said *old* towels) into 2" strips, get them good and wet with WD40, then just wrap it around each spoke and pull back and forth a few times, running up and down the spoke. Since I switched to the chain wax ("New" Bel-Ray Super Clean), I don't really get any fling off. The wheels wipe clean when washing, I haven't had to do a major cleaning all year. The trick to the chain wax though is that you have to spray it on when the chain is warm! That lets the wax melt then it sticks. If you spray it on a cold chain, it flings off just like oil or regular chain lube. Not a big deal, you just spray the chain as soon as you get back from your ride.
