3) Work when the car is completely cold.
4) Use plastic bags/aluminum foil/plastic wrap and wrap anything that shouldn't be wet.
5) Park in an area where the run-off won't damage anything and will be easy to clean up.
6) Pump up the garden sprayer, and spray all areas that need cleaning.
7) Using the nylon long-handled brush on the broomstick, agitate any areas that need extra attention.
8) Soak for 10 minutes (don't go longer on aluminum surfaces with the Simple Green, it WILL etch it)
9) Hit it with the hot-water pressure sprayer. Grime will start flowing off in large amounts.
10) Repeat the sequence in really dirty areas.

Your car will shine.
