Does Winsol have anything that will get streaks out the first time, everytime?
A qualified yes. We have cleaning products that we manufacture for other markets that will remove the black streaks with a single cleaning. If they damage the awning in the process, however, we are not really helping you. The DEEP CLEAN is generally as aggressive as you wish to get. A more aggressive cleaner or application system can potentially damage the awning and leave you to foot the replacement cost.
