A milking cluster washer or cluster washer is an integral part of the complete milking equipment cleaning system. Washing the milking clusters is essential for regular and efficient milking, as milk can easily remain trapped in the nooks and crannies of the clusters. Custer washers are designed to remedy this situation. Generally, cluster washers are created to flush out the remnants of the previous milk round from all the internal and external portions of the milking cluster by forcing the wash solution or water through a nozzle to clean out all milk remnants and prevent clogging through the use of a pump.
