How Picklex 20 Works Picklex 20 performs multiple jobs by brushing, spraying, wiping or dipping process at room temperature. Picklex 20 removes all residue from a new metal surface such as, mill oil, cutting fluid, dust, finger prints, removes surface rust (red and white rust), provide a conversion coating (protective coating), seal the coating and stop further oxidation, all in one step in one minute, completely preparing the metal surface for Welding and Finishing. It safely works on all ferrous and non-ferrous metal surfaces, such as carbon steel, stainless steel, galvanized steel, aluminum etc. No Rinsing needed! No waste to throw away! It's that simple! Picklex 20 Green Technology Picklex 20 is the only Pre-treatment (conversion coating) which is capable of completely removing mill oil/cutting fluid, surface rust, provide the conversion coating, seal the coating and stop further oxidation, all in one step in a minute on a new or blasted metal surface at room temperature without rinsing. It provides excellent bonding with the top coating and much longer paint life than if the same paint job was performed over a blasted metal surface. Eliminates the use of hazardous/toxic chemicals.
