For long-lasting windshields, take our advice and use a Minky Towel for waxing your polycarbonate windshield, even if it has a scratch-resistant coating. This unique towel is made from Minky fabric, which is a stretchy, plush microfiber material constructed with 100% polyester fibers. The soft pile of raised loops or strands of fibers makes it stand out from a regular microfiber cloth.
