If your car is well protected by either a wax or synthetic sealant you will find majority of your water will come off.
If you have yourself a air compressor in sight you can also air dry the majority of the car avoiding any touch. But by far the biggest thing is;
do not use a sponge, do not use a chamois as you will definitely scratch the paint work.
Use a microfibre waffle weave drying towel as if any dirt has been missed and you wipe over it will sit into the center of the waffle itself and not the surface unlike directly on the surface of a chamois.
2 bucket wash method, snow foam wash or a high pressure wash is always the best and is how i always personally wash my own car weekly.. sometimes twice a week (im not normal).
So my advise for tips and tricks.
1. High Pressure Water to Wash the car is a must
2. Snow Foam connection for a high pressure water system (will fit 95% of machines) also a lot of fun
3. Air Dryer of some sorts
I could go on, ill leave it at 3 for now
