I have bought the higher grade micro fiber towels (400+ thread count) from WM but still feel the quality could be better for dyring after washing , polishing , waxing , etc. with less swirl marks and in some cases fine scratches left as a result . *That said , what are your favorite micro fiber towels you have had good luck with that are a good buy ? What is important to me are : Larger size with some heft to them , good quality stitching , high thread count - most important are micro fiber towels that won't scratch or create swirl marks ! Hopefuly those with more experience than me in detailing undestand where I'm coming from and can chime in ...
