Need something to get dirt off rims
Then, get a plastic brush with a handle to help clean away some of that grime.
Hit it again with some water and call it a day.
To make it easier down the road, i would do the above. When the wheels are nice and dry, spray your wheels with a spray detailer and polish them. The wax on the wheels will act as a barrier to help in keeping that grime off your wheels. You should only have to spray your wheels off the next time, since their coated with that wax. Hope that helps- you have some nice rims!
Simple Green, as it comes from the store, is concentrated as crap. I use over a half a bottle of water and my Polished Z06s are still looking good as new. You can dilute the absolute **** out of Simple Green and it keeps working like a charm
