A wiper control method and a wiper control device are provided. An arm falling position for stopping wiper arms for a predetermined time is set above a lower reversal position. When the wiper arms stopped on the side of an upper reversal position with respect to the arm falling position, such as a service position, are moved to a storage position set below the lower reversal position, or when a wiping operation is to be performed again, the wiper arms are temporarily stopped for the predetermined time at the arm falling position. Then, after the predetermined time elapses, the wiper arms are moved to the storage position in the case of a storage operation, and moved to the upper reversal position in the case of restarting, and then the normal wiping operation is performed.
