Since COVID-19 hit, we’ve been getting more requests about how to disinfect touchscreen surfaces. It is important to realize touchscreens are sensitive to chemicals and having liquid applied to them.

First some warnings:

  • Touchscreen display modules are not sealed and can be damaged if liquids are sprayed or poured directly onto the surface. Cleaning cloths should be wrung of excess liquid prior to using on device surfaces.
  • Avoid Isopropyl alcohol at concentrations greater than 70% and non-diluted bleach or ammonia solutions. The use of incorrect solutions can result in visual impairment of touchscreen, discoloration, and damage functionality.
  • Do not use any cleaning agents that are labeled as corrosive or abrasive to glass or plastic. This includes solvents (Like Formula 409), acids, ammonia, and any cleaning agents containing an abrasive.
  • Do not wipe or scrape any surface of the device with anything abrasive (i.e. steel wool, cloth with steel threads, scrubbing sponges, razor blades).

Cleaning and disinfection are two steps. Cleaning refers to the removal of germs, dirt, and impurities from surfaces. Disinfecting refers to using chemicals, for example, EPA-registered disinfectants, to kill germs on surfaces.

To clean:

  • Use a clean, dry, non-abrasive cloth to gently remove loose dirt or smudges. We recommend a 3M 9021 Microfiber Lens Cleaning Cloth.
  • If further cleaning is needed, use a commercially available product such as Klear Screen or Glass Plus to dampen a clean, dry, non-abrasive cloth or use pre-moistened wipes designed for cleaning electronics. Avoid contact with the edges of the film or glass, and with the flex tail.
  • Allow the surface to dry.

To combat COVID-19 and disinfect, follow the steps above, then:
