Ok, here's my routine:
a) Rinse off all surface dirt on the body of the car and rinse the wheel wells out.
b) I start on the left side by cleaning the wheels and tires. For the wheels, I use Espree's Wheel Magic formulated for clearcoat wheels (green). For tires, I use Westley's Bleche White. I spray the tires and rims and let it sit for a minute. Then I scrub the tire with a wire tire brush so that I can get rid of all the deep down dirt on the tires. After scrubbing the tires, I take a wash mitt and clean the rim along with the edge of the fenderwell and the splashguards. Then I rinse.
c) I use Meguiar's Car Wash Soap and a wash mitt to clean the body of the car. If I'm in the sun, I will do the car a quarter at a time to prevent the soap from drying on it. I tend to start from the front and work my way back. Then I rinse.
d) I repeat steps a-c on the right side of the car.
e) I use a chamois to dry my car. I prefer to get the 5 1/4 square foot chamois so that I can cover more area. Also, I will use a can of air to blow out water from the gas tank door. I also dry the door jambs as well as the trunk jambs. I will also wipe the sunroof track to get rid of any moisture.
f) After drying, I clean the inside of the car. The first thing I do is get rid of all the dust and crud with a damp terrycloth towel. Then, I use a can of compressed air to get the crud and dust out of small crevices. For the dash and other vinyl surfaces, I will use Meguiar's #40 Vinyl cleaner and conditioner. I spray that on a wax applicator pad so I don't get any on the windshield or other windows. For the glass (including my sunroof), I use Trak Auto's Window Cleaner and newspaper. After cleaning the glass, I apply Rain-X to the exterior glass surfaces. Sometimes, I will polish my rims with metal polish in order to get rid of any oxidation.
g) Usually, I will wax my car with Meguiar's once a month.
Once I am finished, my car is cleaner than most pros can make it.
