Touch screen terminals, kiosks, and tablets are increasingly used in retail stores and restaurants. With COVID-19's arrival in the United States, touch screens need to be frequently and thoroughly cleaned and sanitized to reduce the risk of spreading infection. Modern PCT panels are very durable and resistant to liquids. Older resistive touch panels are more sensitive to cleaning and not as resistant to liquids.

 

Supplies

  • Lint-free or microfiber cloth
  • Touch screen safe cleaning solution
    • Alcohol disinfectant wipes such as Clorox Disinfecting Wipes
    • Between 40% and 70% isoprophyl alcohol
    • Household bleach solution (1/3 cup of bleach per gallon of water)

Step By Step Process

  1. Power off the system
  2. Moisten a soft, lint-free or microfiber cloth with the cleaning solution (NEVER spray the glass cleaner directly onto the display. The liquid can seep into the corners and in between the thin layers)
  3. Wipe the display surface in a circular motion to remove any dirt or residue from the touch glass (Apply only slight, gentile pressure as you wipe the touch screen. The circular motion will ensure that any streaking is reduced as much as possible)
  4. Use a dry, clean, microfiber cloth to gently dry the screen (NEVER dry with paper towels, facial tissues, or abrasive cloths. These items can cause tine scratches in the touch screen. Always use a dry, clean, microfiber cloth to gently dry the screen)
  5. Power the system back on (Once complete and you're certain the surface of the touch screen is dry, you can turn the touch device back on)
