2007 Black M6 Paint Marring/Hazing

So I just bought my 1st clack car 3 months ago, 2007 black M6. Only has 29K miles on it. So I get it detailed with claybar and now I noticed some hazing side to side. I talked to the detailer about it and his response was it's caused by washing the car..... What??

So I clearly thought this guy was full of crap. I went and researched the best detailers in Tampa. I had them come out. They striped the car of all wax and you could see it all over. They did there Paul Dalton paint correction process and they showed me each section as they did it. Car looked brand new...... Finally gone....

Not so fast. I washed the car yesterday in the shade with turtle wax ICE shampoo, soft mit and microfiber towels to dry. THEY ARE BACK!!! I called the detailer and they are coming back out to do it again for free, but could this be me doing it with simply washing the car? Could the paint be that soft that by me simply drying the car it leaves hazing? Anyone else experience this?
