Mamiya 6 75mm Lens: Cleaning Residue from the Rear Elements

Servicing a Mamiya 6 75mm lens. As you can see in the second photo, this lens had quite a bit of residue in the rear element group. Fortunately, I was able to clean this off and the lens now works perfectly. The final photo shows the last step in the process and that is checked and adjusting, if necessary, the focus of the lens.
With Mamiya 6/7 lenses, I am generally successful in cleaning residue/artifacts from the elements. With many Mamiya RB and RZ lenses, this is not always the case as damage has been done (often between cemented elements) that is not reversible without specialized lens service such as recementing and/or recoating which normally is not economically feasible.
