I've been following the directions on the bottle, Using Microfiber Products to wash and dry the vehicles, work awesome however... I noticed that any microfiber I use to wash with looks destroyed by the time it's done. Even if the vehicle is not really all that dirty. Am I doing something wrong or is the just the nature of the microfiber? Anyone else have this issue.. Any suggestions for me on maintaining the microfiber? Even after washing the microfiber it still looks terrible.
