Organic substances such as: oil, grease and fingerprints will be a source of corrosion and localized corrosion. Because of these substances can act as a barrier, they can affect the chemical and electrochemical cleaning effect, and therefore must be thoroughly cleaned. ASTM A380 is a simple water (WATERBREAK) detection of organic pollutant test. During the experiment, the water from the top of the vertical surface of the water, in the water downstream to process will be divided along the surrounding organic matter. Flux and / or acidic chemical cleaning agents can remove oil stains and grease.
