@Turbothinghy .. Here the steps which I follow to clean the car 1. Dust it off using duster (Jopasu / Microfibre cloth). 2. Use No rinse wash concentrate (Optima no rinse / Ultima waterless wash) if the car is less dirty. I fully shampoo it when it gets really dirty. 3. Spray the diluted No rinse concentrate panel by panel starting from top & then go down. 4. I use 3-4 microfibre cloths for the entire car. fold them to quarter so u get 8 sides to work on each cloth. So u can always use fresh side. this would reduce the swirls from developing. 5. Once the each panel is wiped using the MF cloth, use separate dry MF cloth for to remove water streaking from each panel. The whole process takes aprrox 30-45 mins. Hope this helps.
