like dark said, any kind of physical contact can cause swirls. i think you are washing your car too frequently too. i know youre trying to take good care of your baby, but you might be over doing it. detail nerds even dry thier cars contactless with leaf blowers, i just got an electric blower one from the box store for ~150,use it for the yard too.

something i learned is the importance of the pre-wash. try spraying as much dirt off the car with just water before you even touch it. that way when you finally make contact, hopefully 80% of the abrasive dirt is off the car already. spray it with water, let it sit/soak/soften, spray it again all with just water
