Step 5: Clean your wheels last
Brake dust and other road grime is a pain to clean, but it's also very dangerous for the health of your paint, and it's not the best for you, either. Whatever rag you decide to use for your wheels, remember to never use it again for anything else. Period. So long as you're careful not to scratch the paint, you can get away with retired socks here. Just spray your wheels down like you did the rest of your car -- or a little bit more, since you know your wheels are dirtier -- and wipe up. If I'm cleaning inside like this, I generally do the wheels twice, just to make sure.
And that's it. The end result is a perfectly clean, shiny car like mine. Even if you take your sweet-ass time about it, it's faster and easier than washing your car with water. You're also saving the planet, which is nice.
