Does it still squeal at the end if you stop ten minutes before the end
and clean and then restart with overlap?
See my technique for loading C-0s that doesn't involve opening them:
Also, see my posts about lubrication and my favourite lubricant:

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.
