avionics care tips from garmin: cleaning and disinfecting guidance
April 6, 2020
Since cleaning avionics is a great way to not only maintain a clean cockpit environment, but also help prevent the spread of disease, Garmin has released its 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.
