How to clean your POS?
Before cleaning your POS systems Although all of Penetek systems are with IP65 standard at front, for the safety precaution it is recommended to turn off the device and then unplug it from the power source before clean your POS terminals. Cleaning your POS systems Our current recommendations for cleaning POS systems as below, you can choose from one of the cleaners and spray it onto a cleaning cloth or towel. Then, genteelly wipe the surface to be cleaned.
Clean the touch screen with 75% alcohol, or 0.75 liter of 100% alcohol mix with 0.25 liter of pure water.
Bleach – figure 1/3 cup bleach per gallon of water for mix ratio
Clean surfaces with warm soapy water.
*Do NOT use following material/liquid to clean your POS systems
Detergents with abrasives
Detergents with fluoride
Detergents with ammonia at concentration > 1.6%
Highly concentrated solutions of alcohol-based.
Isopropyl Alcohol at concentration > 70%
Methyl Alcohol or Ethyl Alcohol at concentration > 35%
Strong alkali lyes
Thinner or benzine
If you want to “further-clean”, you may consider getting a handheld UVC product for a specific area and safe UVC cleaning (after surfaces have been wiped down). After cleaning your POS systems If you are using 75% alcohol or similar, it should only take a few seconds to dry out. Others, please wait for the unit to dry before switching the system back on. (If an area gets too wet, you can wipe it with a paper towel or a dry cloth.) Other than standard POS hardware, Penetek also offers the choice of antibacterial touch screen with antibacterial coating on POS hardware. If you have such demands, please contact us at email@example.com. We will get back to you as soon as we can.
