The Professor's 100% alcohol. Cleans ∗anything∗!!! :-)

Way back in #805 I used some emery cloth to scruffify the rollers---they
were too shiny---then cleaned them with isopropyl alcohol. It's also OK to
take the edge off a tiny bit if bowed/chipped (or get Martinized where he
turns them into something like a radial tire). You really want the meat of
the pinch roller biting down on the tape---as much of the roller as
possible, not the edges.

I believe Ken M. dipped his rollers into isopropyl to loosen up the
stubborn ones, and that may be the way to go. I got some of that 100%
stuff in there, and in lieu of using oil to loosen 'em, the 100% alcohol
worked great. I bet the regular isopropyl would work well, too (100%
alcohol is not available to us common folk). I don't know the long term
effects of such harsh stuff, though, but oiling the pinch roller's axle
also has its issues. YMMV.

Another trick: Look carefully at the edges of your tapes. If the pinch
roller isn't absolutely straight, you may see the edges of your tape
becoming worn/jaggy or even bent (as in a long line down the length of your
tape). I have used a big pair of pipe pliers to straighten out some cocked
rollers so the tape flows perfectly straight and no longer has the tendency
to be pulled to one side or the other.
