Turtle extreme use to be pretty good for wash. Wax is a pain in the but to get good, always leaves marks on the car so I use to turn the car in for that.. or yeh I turn the car in for hand wash too, but cleans it some times a year by my self too.
I do these steps when I clean it:
1. Place the car in shade and let it cool down
2. Start with the garden hose at the bottom of the car and soak it upwards from there (start at bottom so that dirt dosnt stick to dirt as is the result if starting from top).
3. Clean the wheels
4. Spraying the car with a high pressure-wash thing (dont know the english word) in all gaps and places where dirt can hide.
5. Take a clean bucket and a big sponge of good quality (please don't use the cheap yellow junk!), mix the shampoo and with water according to the box.
6. Start from top and work down from front to rear of the car. I do never use circular movements (Im not karate kid!

And circular movements will make scratches. ). I work with much water/shampoo in the sponge (and do never use up all water in it before re-soaking) and in straight lines from front and backwards as said.
If I drop the sponge on the ground.. I do throw it away and use a new one! Stones are bastards even when they cant be seen by eye!
7.Then I rinse the car with my garden hose.
8. Dry it with those towels that I dont know the name of hehe, use the artificial once since they most often suck water better. This towel must be clean and if I drop it on the ground I have a replacement to continue with, cause (as said) small stones is not very gentle to the car. Im very careful to never let the car dry by it self since there is minerals in the water that will leave marks.
9. Dry all the gaps, door-frame and such.
Or you can do like this guy
