Avionics Care: Cleaning and Disinfecting Guidance

Cleaning your Garmin avionics is a great way to not only
maintain a clean cockpit environment, but also help prevent the spread of
disease. Because our products are built with sophisticated electronic
components and touchscreen materials, it’s important to take special care in
choosing which cleaning method is best for your specific Garmin products. Below
are general guidelines for cleaning the touchscreens, buttons, knobs and bezels
on Garmin avionics. 

NOTE: The following guidance is intended to help reduce
the spread of disease while preserving the integrity of Garmin aviation
products. Garmin does not guarantee that it will do so in all cases. For
general cleaning and disinfecting guidance, please refer to CDC guidelines and
other applicable guidelines.

Cleaning and Disinfecting:

• Cleaners containing ammonia will harm the antireflective
  coating on many Garmin aviation display lenses.
• Disinfecting using a solution of 70% isopropyl
  alcohol that does not contain ammonia is preferred. Solutions of up to 91%
  isopropyl alcohol are also acceptable.
• Clean the display lens using a clean, lint-free
  cloth and a cleaner that is specified as safe for antireflective coatings.
• For other exposed surfaces such as knobs,
  buttons and bezels, a damp cloth with soap and water is acceptable. Garmin does
  not recommend bleach-based cleaners, ammonia-based cleaners or other harsh
  chemicals on any surface.
• Remove all soap/soap residue to prevent buttons
  and knobs from gumming up or becoming slippery.
• Many aviation products are not rated as
  waterproof. Spraying or wetting the units to the extent where moisture could go
  beyond the exterior surfaces could damage the unit.
