on the stock radio/tape player. to the right of the opening for the tape slot, there is a tiny button, next to that the word "clean"
what is it for ? i have no owners manual.
thanks.

I don't know for sure, but I'm guessing it's like a dolby sound button that will clean up the tapes sounds. Like cleaning up the pops and hiss' of the audio.

Or maybe it's to demagnetize the heads (basically cleaning them).
