Hey guys. Bought a pack of 12 autozone microfiber cloths. My question is, are they safe compared to the more expensive ones? I did all my research prior to purchasing. 80/20 blend, deep fibers, no rough edges etc. Wash seperately with scentless detergent and dry on low heat etc. My question is though, should I worry about scratches? I have been eyeing the Griots Microfiber towels but I just don't know if theyre worth it. Just recently, when the sun hit my car just right I saw some hairline swirls. I have not seen them before but then again I'm not fulling blaming the towels either. I did the CD scratch test and I always make sure there is no grit before each swipe but I was just curious what you guys thoughts were on cheaper vs expensive towels. The car is new so for all I know they could have been there before and I just never saw them. If this is the case, I don't want to dump all the money I spent on these towels to go and blow more. What do you guys think?
