PE-120 – Citric Acid Passivate Cleaner (10% Solution)

PE-120 – Citric Acid Passivate Cleaner (10% Solution)PE-120 is a citric acid–based passivation cleaner formulated to remove free iron contamination, light oxidation, and surface residues from stainless steel components while restoring their natural corrosion resistance. The solution is prepared as a 10% citric acid mixture with deionized water, providing a consistent, ready-to-use formulation for precision cleaning and passivation applications.Citric acid passivation works by dissolving embedded iron particles and contaminants from the stainless steel surface. Once these contaminants are removed, the chromium in the alloy is able to form a stable chromium oxide layer that protects the metal from corrosion and rust formation.PE-120 is particularly effective in immersion and ultrasonic cleaning systems, where ultrasonic cavitation allows the solution to penetrate small crevices, blind holes, and complex geometries that are difficult to reach with conventional cleaning methods.Typical ApplicationsStainless steel machined componentsMedical device partsAerospace and precision manufacturing componentsFood processing equipmentLaboratory hardware and fittingsFabricated or welded stainless steel assembliesKey Features10% citric acid solution prepared with deionized waterDesigned for stainless steel cleaning and passivationEffective removal of free iron and light oxidationHelps restore the protective chromium oxide layerCompatible with immersion and ultrasonic cleaning systemsSupplied ready to use in 5-gallon containersAdvantages Over Nitric Acid PassivationCitric acid passivation offers a safer and more environmentally friendly alternative to traditional nitric acid processes. It eliminates hazardous nitric fumes, simplifies handling and waste disposal, and provides reliable corrosion protection for stainless steel components.PE-120 provides manufacturers with a simple, effective solution for improving the corrosion resistance and cleanliness of stainless steel parts used in demanding industrial applications.
