7-10 MINUTES OF MAIN CIRCULATION TIME (MAIN RINSE) IS RECOMMENDED

Cleaning must be long enough to ensure proper contact time between water, detergents and all milking system parts and surfaces, and to allow optimal mode of action of the detergent.

On the other hand cleaning must not be longer than needed because temperature will then drop too much, which can result for example in sedimentation of fat particles (will solidify in low temperatures).
