Isopropyl alcohol is used for cleaning :
-Electronic devices, such as contact tips (like those of ROM cartridges)
-Magnetic tapes and disc heads (such as those of audio and video recorders and floppy disk drives)
-Laser lasers on optical disc drives (for example: CD, DVD) and thermal paste removal from heat sinks and integrated circuit packages (for example: CPU)
-From 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 slates.
It is used to clean the LCD and glass of the computer screens (with some risk for the anti-reflective coating on some screens) and is used to brighten phonograph records in bad condition in case you want to sell them second-hand.
Isopropyl alcohol should not be used to clean vinyl discs, as it can cause the vinyl plastic to become stiffer. It is effective in removing traces of glue from some adhesive labels, although some other adhesives used in tapes and paper labels are resistant to it.
It can also be used to remove stains from most fabrics, wood, cotton, etc.
