CMA Spray Pickles effortlessly remove tarnish, oxide layers, scale and extraneous rust. A bright, metallic clean surface is achieved. Weld seams are also cleaned. Before processing, an indicator can be added to the CMA Spray Pickles, which makes the work process easier to follow, reduces the formation of nitrous gases and prevents the formation of nitrite in the waste water. CMA Spray Pickles are free of hydrochloric acid and chlorides.
