Could this be what’s needs cleaning? Seems to be a pressure switch

I don’t know where you’d find a stereo shop these days that would have one, but if you look online, you can find a cassette “head cleaner.“. It looks just like a cassette tape, but the ribbon is a little rougher and it’s coated with whatever that will clean the head that reads the tapes. That’s what you want to clean the head.
