ABSTRACT:
A method of washing a blind which assures that a gap between adjacent louvers of the blind can easily be reduced to a shortest distance and dirty material can reliably be removed from the louvers. The method is practiced such that while the distance between the adjacent louvers is widened, a coil spring-like spacer is pressed against the blind. Offset ring-like portions of the spacer are inserted between the vertically adjacent louvers, and thereafter, the distance between the louvers is reduced to the diameter of a wire material forming the spacer while holding the offset ring-like portions in a clamped state. Subsequently, while the foregoing state is maintained, the blind is washed in a washing liquid circulated by a recirculating pump. Supersonic vibrations, generated by a supersonic vibration generator, are applied to the washing liquid. Then the blind is rinsed in a rinsing bath, and finally, after the coil spring-like spacer is disconnected from the blind, the blind is dried.
