Direct water at an angle between 15 and 30 degrees from the surface to rinse it. Continue rinsing until all evidence of cleaner and soils have been removed from aircraft. (5)  Deluge  rinsing. To prevent buildup of salt deposits, the deluge rinse facilities shall be used as fre- quently as possible. NOTE Use of deluge rinsing facilities does not replace aircraft washing requirements. 13-2
