Car Cleaning Myth: Diapers, old t-shirts and flannel cloths are best for detailing

Will this ever go away?  I've been trying to debunk this myth for the better part of twenty years.  Never use diapers, old t-shirts, old bath towels, etc., on your car.  They may feel soft, but they are stitched with polyester thread.  I promise you, the polyester will scratch and swirl your car's clearcoat.  Use microfiber towels designed for car detailing, like Meguiars Supreme Shine Microfiber or Cobra Microfiber Detailing Cloths.
