Use only high-quality electronic-grade isopropyl alcohol of at least 90 percent concentration as a cleaning solvent.
The isopropyl mixture must consist of alcohol and distilled water only.
Use only nonabrasive, lint-free cloths, and/or swabs to clean the tape path.
Follow these precautions:
Do not use cleaner solutions that contain lubricants. Lubricants leave a deposit on the tape head and impair
performance.
Do not use alcohol cleaning solutions on the rubber gripping fingers on the takeup reel.
Do not use aerosol cleaners. The spray is difficult to control and often contains metallic particles that can
damage the tape head.
Do not use soap and water on the tape path. Soap leaves a thick film, and water may damage electronic parts.
Discard used cloths and swabs after use. Even if they appear clean, they are contaminated.
Do not use facial tissues. Although they may seem effective, they leave highly abrasive lint in the tape path.
Table 11.36.3-1 indicates the cleaning criteria for the KS-23909, L21 9-track tape drive.
