I recently got my windows tinted and there are some water streaks from them putting the shop putting the tint on, I was wondering what do I need to use to clean the windows that wont mess up or sratch the tint? Just soap and water and a soft cloth? What kind of cloth should I use? There is also a little bubble near the back of the passangers side door window, What can I do about taking it away? Should I just not worry about and try to fix it if it gets worse or should I take it back to the shop in a couple of days since there is a lifetime warranty? Let me know what I should do.
