Dynamic detailing in Santa Clara CA installed ceramic pro 9h on my NB. To learn proper detailing from scratch is way outside the scope of this forum's knowledge unfortunately (seeing how many people go to hand wash places

). To wash my coated car I use similar ones to these
https://www.amazon.com/RAG-COMPANY-Professional-Microfiber-Detailing/dp/B00GXRG64I. Things like wax will not stick to a coated car and smear or streak.
My wash steps:
Fill 1 clean bucket a grit guard, water and megs gold or other soap
fill another 5gal bucket with clean water and a grit guard.
Setup my power washer
Spray wheel cleaner like BDX on wheels and exhaust tips (I use mostly 3d detailing products out of convenience)
Let sit 1-3m (dont let this dry on, it stained my old DIY painted wheels)
Spray bug remover as needed
Power wash car top to bottom attempting to push dirt off
Use foam cannon and spray car
Wash car, flipping towels into many squares. I never use the same section of a towel twice unless its spotless.
Work in airflow direction, 1 panel at a time, top to bottom. (I do least dirty to most dirty: roof, hood, roof side panels, quarter panels, doors, hatch, bumpers)
What I do is lightly wipe the dirt off, then when the entire panel is clean I take a fresh section of the towel and scrub lightly if to get missed stuff.
Clean wheels with wheels only Costco yellow MFs
Clean tips
Clean glass
Power rinse car
Dry car using blow dryer or drying towel sprayed with quick detailer (never dry a car with a towel without a lubricant)
Personally I recommend watching every one of Larry Kosilla's videos (AMMO NYC) to begin to get an understanding. I also like /r/autodetailing.
Hot tips:
keep entirely separate towels, buckets, etc for the wheels.
If you drop a towel in the dirt unless you can pick it all out throw it away.
You can always use more towels, you can never swirl less (without paint correction)
