I use 1 bucket first with NXT wash, a mit & soft MF brush.
1, hose the whole car & jet wash wheels& under all arches
2, wash the car from lower trim line down & rinse.
3, mit the wheels inside & out, making sure that the insides are as clean & tar free as the fronts & rinse.
Fresh bucket of NXT + another with just water to rinse A FURTHER MIT (I don't use the same one for lower bodywork & wheels).
1, roof & glass, then rinse.
2, bonnett & front, then rinse
3, each side & rinse (before doing the other)
4, and finish with the dirtiest part of the car which is the back (normally).
Sonus der wonder towels are the muts to dry with..
1, Use one to do first dry sweep.
2, then use a further MF towel to QD ( loads to try from, megs NXT is a good starter, quickshine good & others I am trying) & a further Sonus to buff off.
3, Glass....megs I prefer, AG..dusty, again loads to try which I am working through again.
4, wheels, I dry with paper towel & QD & finish with AG alloy wheel seal which is very good (& I have mentioned before)
5, Tyres..... Megs endurance gel takes some beating.
6, Interior, got to be poorboys natural look everytime.
7, door shuts QD and paper towel
8, pipe tips.....autosol
I can rattle through that in 1 hour exactly
I have only had my G220 for a few months & results on my Phantom Black A4 are amazing.
I would normally give the full treatment twice a year, with polish & wax every other month, sometimes every month depending on time.

I am by no means an expert & do not profess to be, but I think I know how to clean a car (a bit)..........
