Can anyone suggest the best method including cloth type and possible cleaning solution to use on the outside glass on a vintage Bolex anamorphic lense?

Does anybody know the proper scaling numbers to use when using a 1.5x anamorphic adaptor on the new Small HD AC7? I assume starting off with auto scale or 16:9 is a good start as the signal is from a Canon C100 Mark II. Not sure how to fine tune to make the image close to what it will be in post when we'll desqueeze. Thanks
