Microscratches do not need to be a part of life. It all starts with preparation.

To remove them, you'll need to use an orbital buffer. A professional detailer will be needed for this and it should cost no more than $200.00.

Steps to avoid the scratches in the future:
1) wash the car with water (need not be distilled)
2) use separate towels (terry cloth) and a separate bucket to clean the wheels first
3) use another set ( of microfiber towels and another bucket) to clean the lower portion of the car using a high quality car wash.
4) Use a final set of microfiber and yet another bucket to wash the remainder.
5) Rinse and dry with clean microfiber towels moving in one direction only. Never dry in a circular fashion.
4) wax with a high quality wax that contains no polishing compounds, whatsoever.

Though, if you've not clayed your car, you'll need to do that before even starting the orbital buffer. Given your expertise, I would leave that up to the professional detailer. It's easy to avoid scratches on even the most delicate finishes. Swirl marks are evidence of improper cleaning, nothing else. They are caused by humans, not mother nature.

The best place to read more is Autopia Computer Products Inc. or you can purchase several books from that site. It's also a great place to buy product. Remember the brake dust is made up of microscopic iron particles coming from your rotors and pads. They are very sharp and will scratch your paint on contact, if you use the same towels for wheels that you do for paint.

That right there is the most common cause of swirls.

Best of luck and don't freak. I could remove them and provide you with a factory fresh finish in less than 1 hr. if with a $100.00 orbital buffer and some high quality product, as can any professional detailer.
