For cleaning reels, tanks, etc, I've turned to the family dishwashing machine. I've encountered no problems, and the detergent is able to reach tiny crevices that often elude brushes. And the whole process is effortless; I would recommend the upper rack, and air, versus heated drying, especially for plastic reels. For stainless, no worries about overheating. The dishwasher rinse aid might even sub for PhotoFlow, but I'm not gonna try!
