I've got the aluminum rims. Cleaning them is a real chore. Is there anything out there that will allow me to just spray on, let it sit for a bit, and hose off? (It has to work. I tried one thing, and it was horrible. Didn't work at all)
I have a pressure washer, and I hate that method for the spray that is reflected back just gets me all wet. when it is cold outside, you freeze)

 

This won't help with cleaning, but next time you buy brakes, ask for Ceramic pads...they dust a heckuva lot less.

Even the dealers have them as an option. The difference was amazing on my friend's '07

 

I've used a number of different products ... Meguiar's makes a good wheel cleaner. I also have a "store brand" which has "Teflon" that does surprisingly well. Here's the key: first, get the wheels really clean. This will require working with a soft brush or sponge with the wheel clearner. Once you have the wheels looking good, clean them every 3-4 weeks with the spray-on cleaner and that should keep them looking good over time. (If you wax your wheels after they're cleaned, it's much easier to clean for the next few months too)

I'm not familiar with your particular wheels, but I have the new 2008 T&C with the aluminum wheels.
After I get a carwash, I take a towel and a spray bottle of 409 cleaner and spray a wheel with it, then
I use the towel to wipe all the grime off.
It takes all the dirt, grease and grime off and polishes up the wheel nicely.

Thanks and see you out there,
