Wooden, long (approx. 2-2.15 m) gutter-shaped shovel with which the bleacher sprayed the linnen - which was spread out on the meadow - with water from the ditch. The combination of the sunlight, the grass on which the linnen was laid and the water made the gray linnen white in colour.
In Germany a copper spoon which somewhat resembles the liquid manure scoop, or a watering can was used for this purpose (1).
