Just obtained a VERY rare old German sniper scope (I collect German firearms), and the optics are internally cloudy. I am willing to disassemble it (done it before with even scarcer stuff), but never dealt with cloudy optics previously.

Is cloudiness (lie looking though a thin fog) caused by condensation inside the scope? Or? Should the Bintel UHTC cleaning fluid take care of it?

Thanks.
