Get some C-zeros (or just about any cassetes that has screws to open them up) and put the old tape in new housings. Easy andmost likely will fix it. Sounds like the tapeis squealing over the plastic guides in the cheap shells.
If you have never opend up a cassette, be careful to keep them flat on a table and donítlet the various parts inside fall outÖ

These tapes are ultra-cheap Certron-brand tapes of the sort you would get at a dollar store. I have scrupulously cleaned the heads and all other parts of the tape path between every tape playback (even when I flip the tape over to record the second side). Some, but not a lot, of oxide is coming off. When I clean the pinch roller (using 91% isopropyl), there is a little bit of brown on the Q tip after one side of the tape has passed.

What might be causing this and what, if anything, can I do to mitigate the problem. In the previous set of posts on the subject, the consensus seemed to be that baking is rarely (but not never) needed with cassettes.
