Caution: Microfiber Towels and Pads
Industrial paint and sealant manufacturers warn against washing your vehicle with the popular microfiber cloths and pads. They are made from 85% polyester, which is plastic. Plastic scratches over time and with repeated use, they will scratch the sealant off the surface and then start on the paint. Your RV will begin oxidizing even though you have meticulously cared for it.
