Bad towels! Years and years ago that's what I kept saying to myself before it was finally easy to find towels that didnt scratch my car. 100% cotton? Hogwash! Today, drying is done best with a Microfiber product. Microfiber actually picks up dust and dirt, and also picks up moisture and minerals that may be left on the vehicle after washing. Never ever try to pinch a penny by purchasing cheap towels, or even cheap Microfiber. Not all towels, and certainly not all Microfiber is the same. I guarantee you will love our Drying products.
