Touchscreen Cleaning and Maintenance

Any standard glass cleaner can be used to clean the touchscreen, but avoid products containing ammonia.

Always spray the glass cleaner on the cloth or towel and then clean the touchscreen.
Glass cleaner sprayed directly on the monitor could possibly leak inside a non-sealed unit and cause damage.

Dirt and fingerprints do not affect the operation of a properly sealed touch screen.

Touch screens that have a deep scratch or gouge in them may be damaged and cannot be corrected with software.
If the cursor is fixed in one spot, and returns back to that spot (even though a mouse was used to temporarily move it), means that the touch sensor is damaged or defective. 

If damaged, the touch screen sensor (7 layer membrane) needs to be replaced.  We can replace touch screen sensors while still keeping the original TFT display panel.  This is much cheaper than buying a whole new touch screen monitor.
