Can you clarify for us if you used the word "Detailing" to mean "Polishing" or "Regular Maintenance"?
The info I put in link above is for "Polishing" or what we would call paint correction.
For regular cleaning of a car with minimal dust, the goal is to not add anymore scratches.
I don't use water to wash the El Camino.
Instead I use a waterless wash product like these two along with many clean quality microfiber towels.
I fold the towel twice, making 8 sections.
Then as I wipe off the sprayed on solution, I rotate my hand and towel to have the towel move to clean portions of the towel.
Try to not allow the dirt/dust to be pushed into the paint by using your fingers to roll as you go.
Rather than a sharp dark line of dust collected on the towel, you want to see it spread over about 1 to 2 inches.
Then move to a clean part of towel for the next wipe.
Since you will wash your microfiber towels, it should not be a concern about how many you get dirty.
Both products have a higher lubricity than a regular detailing solution.
Here is my El Camino (two stage base coat plus clear) with Meguiar's Ultimate Waterless Wash And Wax Anywhere used to clean it and add a little protection..
