Ok fellas what is the beat thing to use on tough black streaks on gutters? I can lighten them up but not remove them.
I'll add one vote to F-13 from Pressure Tek. They are right about not mixing it too strong. I have painted about a 10ft section of gutter because it was too strong. Mix it right and it works great. Mix it weaker and brush it though. Better safe then sorry.
Like I said. The grenade was on the vehicle for a few months and it only removed the clear coating and not the paint. Of coarse it was not brushed or waiped during that time period, but still shows theres more of a window than other cleaners. I tried simple green before and it was a wasted trip to the store. I would use Ace Aluminum brite before simple green, but its all relative to each user I suppose.
So what kind of ratio works the best for you Daniel? Bob's site talks about 50/1, 20/1 etc. I'd hate to repaint haha.
