A method for cleaning a conveyor for agricultural products, such as eggs, and a conveyor for agricultural products, in which contaminants that adhere firmly to the conveyor are removed by the use of an ultrasonic cleaning bath into which a section of the conveyor is dipped with the aid of a deflecting unit. During the normal revolution of the conveyor chain, cleaning of the conveyor chain is carried out even during running operation of the conveying system by means of ultrasound and suitable cleaning agent. A conveyor chain having a multiplicity of rods that are connected to one another via chain links is transported in individual conveying segments of the conveyor. Lying on the conveyor chain, the agricultural products are transported. Deposits of contaminants onto the conveyor unavoidably occur during operation, such as, in particular, as a result of litter or feathers.
