I have used microfiber on my HHR(BLACK) since I got it. Not a swirl mark anywhere. These are the best.
I bought all of mine from AutoZone. I do not know the make up of them(80/20,70/30) but they are amazing.
I got a wash mit, drying towel, detailer towel, wax removal towel.
Not trying to dis our sponsor but get some now, you will not regret it.
My next ones will come from the sponsor!!!!!!!!
