Reverse‐flow washing of a 22‐unit pipeline milking plant in a Turnstyle milking parlour was studied during a milking season. The quantity of detergent solution used/wash was 2701 which was preceded and followed by 4401 of rinse water. Two concentrations of nitric acid and surface active agent were used as the cleansing agent in hot and at one concentration in cold water for 5 consecutive 6‐week periods. Bulk milk and cluster rinse samples taken at weekly intervals were tested for total colony and coliform count. It is concluded that nitric acid 0‐3 per cent w/v plus a wetting agent in hot water is an effective detergent system for reverse‐flow washing of large pipeline plants.
