Hi Karl
I've been using IPA without mixing it with anything for the past 35 years.
I have no idea if it dried out a pinch roller faster or not since I haven't
tried other methods. I have had to throw away some cassette decks that had
odd pinch rollers that I couldn't find new ones anymore, but those were not
many and after 20-25 years of service I really couldn't ask for more.

Cheers
Shai Drori
