Now more than ever, it is important to keep your devices clean, especially high contact devices such as time clocks and keypads. We wanted to provide you with a brief guide on the recommended methods and products to use to clean your devices from School Technology Associates.

Time Clocks 

With a soft cloth use one of the following solvents to dampen cloth with and wipe your clock clean, do not spray clock directly:

  • 1:1 mixture of Isopropanol and distilled water
  • Industrial Cleaner Sabesto
  • Sidolin proNature
  • Top Glasschaum
  • Isopropanol
  • 1:1 mixture of Sidolin and Isopropanol
  • 3M Cleaner

Lysol or Clorox wipes can be used as well.

Additional options to help lower the amount of contamination is to mount Purell hand sanitizer dispenser by the clock and/or by having employees use a stylus when touching the screen.

Biometric Readers (including Time Clocks)

With a soft cloth, using any of the solutions mentioned above, dampen the cloth to wipe the sensor clean. Make sure the cloth is not wet, if the sensor becomes saturated it will get damaged. It is important to use a soft cloth as well to ensure the sensor is not scratched.

Biometric readers only require the finger to touch one small area that is easily wiped down. To ensure it stays clean wipe it down frequently and have Purell hand sanitizer available next to the device.


For Tardy Kiosk, Positive Attendance, and Food Service keypads, with a soft cloth or paper towel use 70% Isopropyl rubbing alcohol to wipe your device clean. Do not spray device directly, dampen cloth and proceed to wipe down device. Lysol or Clorox disinfectant wipes can be used as well.
