Microfiber cloths vary greatly in quality. Here are some tips on how to better distinguish quality cloths from cheap mass-produced ones: a) The microfiber quality: Quality cloths absorb 7 to 8 times their weight in liquids because they have split fibers and thus have a larger surface area for absorption. Cheap cloths usually have unsplit microfibers because the splitting process is very complex and therefore expensive. b) The microfiber size: High-quality cloths have "real" microfibers ranging from 0.01 to 0.02 denier. The more microfibers available in the fabric, the better the results a microfiber cloth can deliver. The fibers of cheap cloths are always thicker (up to 0.5 denier or more, which corresponds to the thickness of a normal polyester thread). c) The microfiber fabric: A blend of 80% polyester and 20% polyamide is the quality standard today, while the luxurious SWISSVAX 70/30 blend will absorb liquids significantly better and faster. Here, too, quality comes at a price. Cheap cloths are often made of 100% polyester or contain only a small amount of polyamide because polyamide is much more expensive than polyester. However, this greatly reduces the absorption capacity. d) The edges: For use on car paint, we believe only microfiber cloths without hems, with sealed hems, or with silk hems are suitable. With microfiber cloths with sewn hems, you risk scratches and/or streaks on the paint.
