Passivation is a process used to enhance the corrosion resistance of stainless steel and other metal alloys. By removing free iron and surface contaminants, passivation helps protect equipment from rust, oxidation, and tarnish—extending service life and maintaining clean, functional surfaces.

At Cleansol, we tailor our passivation services to the specific requirements of each project. Our most-recommended product features citric acid, which is not only highly effective but also safe and environmentally friendly. We also use nitric acid-based passivation compounds when preferred. Our proprietary passivation product achieves impressive results on many types of metals and alloys, delivering a rust- and tarnish-free finish without any manual scrubbing.

Oxygen cleaning is a method of safely and effectively cleaning the equipment and associated equipment used in oxygen-rich environment and other applications. In the pharmaceutical and biotechnology industries, contaminants within oxygen systems pose a serious health and safety risk. The main need for O2 cleaning is to prevent combustions hazards but other important aspects are to ensure safety in oxygen systems (O2 systems are ultra-pure systems) and to maintain system integrity and performance.

At Cleansol, we use several advanced oxygen cleaning techniques to maintain safe purity levels. Our procedures adhere to rigorous ASTM G93-03 standards for oxygen-enriched environments, as well as CGA G-4.1, which outlines the necessary guidelines for cleaning oxygen service materials and equipment. We use both mechanical and thermal cleaning procedures to achieve thorough results. After each step of the process, we perform stringent testing to verify process effectiveness and guarantee that cleanliness levels meet your standards.

While passivation protects and restores the chromium oxide film, there’s another issue stainless steel often faces: rouging. It’s a condition where layers of ferrous or iron oxide get embedded on the steel’s surface, leaving it with unsightly reddish hues. This not only impacts the appearance but can also interfere with the steel’s performance over time. Enter derouging.

Derouging is a specialized chemical process aimed at removing these iron oxide layers. Leveraging state-of-the-art techniques and our extensive experience, we ensure the elimination of these layers effectively. Not only does it take care of the aesthetic aspect, but derouging also preps the stainless steel for an effective passivation process, ensuring the steel retains its inherent protective qualities.
