Abstract
A plastic air intake manifold is cleaned by a washer. The manifold is secured in a water tight chamber and immersed in water. Impellers in the chamber create turbulence in the water to remove oil and impurities located near the impellers. Air jets are activated to produce compressed air bubbles in the water which act abrasively to further clean the manifold. The water, impurities and oil are immediately removed from the chamber by a high power suction water outlet pump.
