Isopropyl alcohol is used for cleaning: - Of electronic devices, such as contact tips (such as those of ROM cartridges).
- magnetic tapes and disc heads (such as those of audio and video recorders and flexible disk drives).
- laser lenses in optical disk drives (for example: CD, DVD) and the removal of thermal paste from heat sinks and integrated circuit packages (for example: CPU) of the keyboard and the LCD screen. Very used in the cleaning of lenses of photographic lenses and contacts of electronic devices, since it does not leave marks and is of rapid evaporation. It is sold commercially also as a cleaner for shales.
