Coastal Puerto Rico eats drone hardware alive. This 5-minute post-flight ritual has kept my fleet flying for years.
Why the island is hard on drones
Salt crystals ride the trade winds and settle inside motor bells, gimbal pivots, and battery contacts. Corrosion starts in days, not months.
The ritual
Power down and pull the battery immediately
Wipe the airframe with a cloth dampened in fresh water — never salt water
Spin each motor by hand and listen for grit
Inspect props for stress whitening near the hubs
Once a month
Open the shell if your model allows it and check for white salt crust on the board. A soft brush and 90% isopropyl handles it.
The payoff
My oldest Mini has 400+ coastal flights. The ritual is why.
