After getting a free sample bottle of Dicor's roof cleaner at the Frog rally in Goshen, I did a side by side test against Dawn, one side of roof with each using same brush. Dawn did a better job of cleaning. Downside to Dawn, it can remove wax from the sides of your rig. I'm not concerned about that because after doing roof, I wash and wax the sides.
