Touch Sensor Care and Cleaning 
The touch sensor requires very little maintenance. 3M Touch Systems recommends that 
you periodically clean the glass touch sensor surface. Be sure to turn off your display 
before cleaning. 
Typically, an isopropyl alcohol and water solution ratio of 50:50 is the best cleaning 
agent for your touch sensor. 
 
 CAUTION 
To avoid the potentially hazardous situations associated with the use of alcohol 
or other solvents which may result in minor or moderate injury or property 
damage: 
•  Follow all instructions and recommendations in the manufacturer's Material Safety 
Data Sheet and product label. 
•  Be sure to follow solvent manufacturer's precautions and directions for use when 
using any solvents 
•  It is important to avoid using any caustic chemicals on the touch sensor.   
Apply the cleaner with a soft, lint-free cloth.  Avoid using gritty cloths. 
Always dampen the cloth and then clean the sensor.  Be sure to spray the cleaning liquid 
onto the cloth, not the sensor, so that drips do not seep inside the display or stain the 
bezel.
