I am a weekend warrior detail guy. I do my own cars and some of my friends.
Here is what I use:
FOR REGULAR WASH:
-2 bucket system: one rinse one wash, both with grit guards.
-2 microfiber wash mitten, one in each hand
-a power washer, I use karcher K2
-Some Quality Soap, I use Chemical guys: "Mr. Pink"
-A gigantic microfiber drying towel, I use Chemical guys "Wooly mammoth drying towel"
-Once dried, I use a different from above microfiber towel, not as large but as thick and finish up all the little water spots with some instant detailer, any brand of your liking would do
-I used a different small microfiber towel for door sills and door jam along with some instant detailer.
-Glass: again different micro. towels: one I keep dry, the other I spray a little bit of window washing spray, then there is this triangle window cleaning tool that does wonder for inside windshield.
I do wheels and Tire Last: Wheels I get majority of dust brake and pollution out by spraying wheel cleaner, letting soak, then power spray it off, I finish the wheels with dedicated separated towel and some instant detailer to remove the last little bits of dirt/dust.
