Griot's Garage is my go to for the best microfiber towels. I've been using Chemical Guy's soap, latest I ordered was the Mr. Pink. I also use their buckets and grit guards. I believe my microfiber wash mitt is from CG's as well. And I bought some stuff from Obsessed Garage to make my electric pressure water even better, quick disconnects and 3/8" hose.
I spray off my cars with the white tip using the electric pressure washer, then foam cannon the car. Do a quick rinse with the white tip again, this gets all the big stuff off. After that I hand wash using the double bucket method.
I use CQuarts ceramic coating and Hydro Silex recharge every couple of months. I'm a little OCD but my wife's old Honda Pilot that was almost 10 years old sold super quick and the paint still looked amazing.
