Just wash correctly. You won’t see many swirls, if any.
edit: oh, i see my post would have made a great SOP coming out of a corporate office. yikes.
Use NXT wash, or any good wash. Use a lambswool mitt, or a microfiber mit (I like the chenille style).
Wash clean–>dirty. This is generally roof, horizontal panels, vertical panels. you may want to keep one mit for the lower panels and bumpers (which should be washed last).
Do not dry DO NOT DRY WITH POLYESTER. Microfiber or cotton. I like waffle weave microfiber.
Probably a good idea to use a spray wax if waxing after washing isn’t on the agenda. Mothers FX spraywax (Pep Boys, KS auto), Duragloss Aquawax (Carquest). It may add 10 minutes, but the extra layer of new wax will help curtail marring/swirl marks.
