I have used many microfiber cloths. I initially used these to clean carnauba wax from my car. It cleaned it very quickly BUT left behind streaks. I tried again on a different panel with more force, but no, the cloth left streaks wherever I passed it. I would have been better off using cloths from the supermarket. I tried them afterwards on drying my car. I simply wiped them and saw with an inspector light that they left lines behind AGAIN. Now I only use them to clean dirt from the dashboard. What a waste of money, I bought three of them and they all perform the same
