A conveyor cleaning system includes a treating region, a processing region, and a conveyor belt traveling from the treating region to the processing region. A distributor positioned across the treating region deposits a film of ozonated water on the conveyor belt. In the processing region, the conveyor belt is exposed to soiling agents such as grease and other animal matter. A high-pressure rinser may be positioned over the treating section such that the distributor is positioned between the high-pressure rinser and the processing region. Ozonated water may be generated by a system including first and second tanks. The first tank is filled with ozone gas and water. After a predetermined time, undissolved ozone gas is released. The contents of the first tank are then transferred to a second tank along with more ozone gas. After waiting a predetermined time period, undissolved ozone gas is released from the second tank.
