The easiest way to dry a kite is to fly it. And the most convenient way to fly a kite is while riding. Either extend your session to give it 10-20mins flying to dry or take it to a park to fly it, maybe land board or practice flying skills or test some adjustments on it.
Alternately unrolling a kite inside and having it loosely arranged or spaced out maybe over some things and it will dry after a few days. Even rolled up in a bag if you have it in a warm or hot location like a car or shed, and it will dry after a while. Leaving the bag open is good for that.
It is quite safe to leave a kite wet with salt water for a few weeks, but the longer you do the more likely mold will grow. It can grow in a few months or not in 6 months. Fresh water grows mold really quick, like days, good reason not to wash kites and handling the fabric damages it. If you do wash a kite dry it well.
For the flysurfer folded TE seam cover that traps sand you can wash it out with a strong spray from a hose hard into it. It might be nice if they didn't use that seam cover so sand wouldn't get trapped and repairs were easier, like on PL arcs.Johhnn wrote:sand getting permanently trapped in the trailing edge
