Personally, I use the suede microfiber just like you get with eyeglasses or sunglasses. Works great for me! Haven't had anything too dirty, but I'm sure I could lightly mist some distiller water and then buff with the suede microfiber. In addition, I believe that 1Z Cockpit specially says that it can be used on navigation touch screens (in the generic sense), but even if I sprayed it I would still use the suede microfiber to buff and dry. I would say 95% of the time all you"ll need is just the MF.
Happy detailing! Enjoy your new car. :xyxthumbs:
