How to remove sand, dust and other particles out of my glider?
The Vortex Holes on every AD glider will help getting rid of most dust and particles trapped inside the glider, during the flight. However, sand for instance, can remain “stuck” to the fabric due to static electricity.

To get rid of the last particles, for instance, suspend your glider from the trailing edge, and discharge the static electricity from the glider with a metallic bar connected to the ground (no sharp edges of course!).
