Use the purple simple green only. It is non-corrosive to metals, non-degrading to plastics and clean rinsing. It’s a cost-effective concentrate can be custom diluted for specific cleaning jobs and used in pressure washers, carpet cleaners, floor scrubbers, ultrasonics, dip tanks and other cleaning equipment. Safely cleans aluminum, stainless steel, polished steel, chrome and other metals.
I use this to clean my guns in my ultrasonic cleaner and also use it to clean my truck’s engine bay. Works better than the green Simple Green.
