For cleaning of Low Vision hardware, a general purpose cleaner such as ‘Spray and Wipe’ is normally sufficient to remove any handling marks like hand prints etc. and spraying onto a cloth or paper towel and then wiping over the device is the best method.
However to clean a screen on any CCTV, a screen cleaning kit available from JB HiFi, Jaycar Electronics and many other retailers, is best for screens. Make sure you don’t spray onto the screen directly in case liquid enters the electronics, but spray directly onto the cloth provided in the kit and wipe accordingly.
Bacterial wipes are acceptable for cleaning hardware, but DO NOT use them on screens as they will often cause smudges on the screen which are very difficult to remove.
Another safe method for cleaning the hardware or screens is to spray isopropyl alcohol onto a cloth or paper towel or tissue. Isopropyl will not leave a residue or melt or discolour the material from which the device is made.
The ONLY safe way to clean a refreshable braille display is using isopropyl alcohol as above. Avoid using any cloth or tissues that may leave behind lint or particles that could build up around the pins within the braille display and cause the pins to lack the movement they require to produce braille.
DO NOT use acetone or nail polish remover on any devices as it will likely melt any plastic surface!
AVOID using any cleaning sprays or tissues that contain aloe vera, eucalyptus oil etc as the residue is very difficult to remove, particularly from screens.
