Mamiya 7 80mm Lens: Cleaning Concentric Rings of Fungus

This Mamiya 7 80mm lens had concentric rings of fungus. Kind of disappointing fungus, as least for photographic purposes as they were not really spectacular looking. But they did clean off well. While some fungus will damage the glass, if your lens has this look, it probably will be cleanable.
When a lens comes in for cleaning, it gets a complete check for focus, rangefinder calibration and meter operation (diaphragm variable resistor).
