Never wash them !
never wash foil kites? why not? the manuals seem to say so... sure your not getting confused with sleis?
14 years experience...
You can spot a persons bar and lines, that have been regularly washed from a mile away, the lines are limp, frayed and aged, the same happens to the ripstop material on the kites - not to mention, if you just take it off, and fly around, the debris falls off. If your constantly washing them, your abrading the surface and forcing the dirt, sand, Chlorine, and Fluorine compounds against the material - rather than leaving it with whatever was lightly sitting on the surface before - every time you wash the kite.
In 12 months with lots of washing, the material starts to feel like silk.
You might have parts of your kite that age, i would just buy new pulleys every year, rather than wash the kite every time.
