Marantz CD73 question and manual request

We inherited a complete tower full of Marantz components. Everything is in pristine condition, however, when we play a CD in the player, there is TONS of noise other than the music (fuzzy, scratchy,) The components sat for several years in storage. Is there an "at home" solution to perhaps cleaning the reader? I also would be interested in obtaining a manual in ENGLISH if anyone has one. Any help will be greatly appreciated.
