Cleaner would only play for two or three seconds at a time, if at all, then stop. The longest I got was about four seconds. Fast forwarding and reminding didn't help. Tape got twisted and pulled out once. It's possible I managed to do some cleaning after about 10 or 12 tries but I risked damaging the unit. I had a similar type cleaner about 15 years ago where you basically just put about five or six drops of the cleaning fluid, which was isopropyl alcohol, on the front of the tape, and it worked fine with no problems such as this.
