The fogging is caused by UV damage. Sometimes you can improve things with cutting compound like T-Cut, but the damage often goes some way below the surface.

Always check the quiescent current in Grundig sets of the late 60s and 70s. The factory in Portugal seems to have had a habit of setting this to 10% of what it should be - good for battery life, but not for sound quality.
