I thought it might be a good idea to post about tape rot, feel free to post questions, fixes or links to anything related. Audio 1995

Thanks for the contribution. I’ve never baked a cassette tape. I wonder if it would have any effect in the infamous TDK TypeIV white spots.
If that's mold or mildew, that might need another solution. I personally have never seen it, I just run into tape rot with R2R more than anything.
