In my 1980 F350 I have a cassette player and I use a CD player with a car kit to play CDs. Just recently when I have the tape in playing a CD it makes a buzzing sound through the speakers. My speakers are brand new. I'm not sure if the tape is dirty or if the cassette player is dirty. Is there any way to clean the cassette player? Thanks.

 

You can clean the head on the tape deck with a Q-Tip and alcohol. The tape it self could be bad. Try blowing it out with air from a can!
