Try
A world for detailers... or
Meguiars for advice.
The steps I follow are
use good quality products NOT washing up liquid.
Hose car down first
Clean wheels bumpers and sills etc first. You might need a wheel cleaner for impacted brake dust, tar and other goo.
If the door shuts are very dirty do them now - otherwise with the rest of the car later on.
Use a fresh bucket for cleaning the car.
Use a lambswool mash mitt, and have a separate bucket to rinse the mitt regularly (this way, you keep your bucket with the car wash in clean - the dirt is washed off into the second bucket).
Dry off with a microfibre cloth. I also use a blade first to get rid of most of the water.
Wax every 4 weeks or so. Use cleaner for black plastic.
In between full washes, remove bird mess etc as soon as (I use a quick detailer spray)
As for which products, there are lots of god quality products.
I have stuck with Autoglym and Meguiars. Other people will have their own favourite products.
