My car's paint is looking dull, think I need to improve my washing routine

I've noticed my car's paint isn't as shiny as it used to be, and under certain light, I can see fine scratches. I'm pretty sure it's from my own washing mistakes, especially living in this dusty environment. I've started researching  exterior car care techniques  that are suited for our climate. A really detailed guide I found explains that the most important first step is a thorough rinse to remove abrasive sand before any contact. It also recommends using a pH-neutral shampoo with the two-bucket method, washing in the shade to avoid water spots, and always drying with a soft microfiber towel by patting, not rubbing. It also stresses the importance of regular waxing to add a protective layer against UV rays. I realized I've been skipping some of these steps, like rinsing thoroughly first. My question for those who have a flawless finish on their cars, what's your exact routine and what products do you trust? Also, how do you handle the daily dust without causing micro-scratches? I'm ready to overhaul my whole approach and would appreciate any practical advice.
