This is a huge score. It is truly a slice of history. You have walked out of a time tunnel with this one. It is a very nice shaver. The problem with cleaning the case in "heavy duty" way, is that you will wash out the "monogram". That is a part of its history. If you want to erase it, that must be your decision and no one should judge you harshly for it. If you want to clean the case, I would begin with a nice soak in very warm water and woolite, the gentlest of detergents. Hand agitate, and let it soak for a couple of hours, then give it several fresh water rinses. It should clean up nicely and the monogram should remain.
