New here but thought I'd register to pass on my tip. I had black streaks that I tried to get off with a number of different products and ideas. None of them worked. Most of the streaks were on the front and rear caps most likely coming from a dirty roof. What I finally ended up with was Mr. Bubbles tile cleaner and a Mr. Clean eraser. Spray on the Mr. Bubbles, wait a minute and wipe off the with Mr. Cleaner eraser.
