What makes us different from others
Effective stainless steel cleaning and passivation
Our passivation process removes surface contaminants and free iron, helping to restore the protective passive layer of stainless steel.
Enhanced corrosion resistance
Passivation supports the natural corrosion resistance of stainless steel, helping components perform reliably in demanding environments.
Suitable for precision stainless steel components
A controlled chemical treatment provides a clean, consistent surface without applying a separate coating or significantly altering component dimensions.
Stainless Steel Passivation: effective surface treatment
C & W Finishings in Bognor Regis offers stainless steel passivation, a chemical treatment designed to clean and condition stainless steel components.
Stainless steel naturally forms a thin protective oxide layer when its surface is clean and exposed to oxygen. Manufacturing processes such as machining, grinding, fabrication and handling can introduce contaminants, including free iron, which can affect the surface and contribute to staining or corrosion.
Our passivation process removes these contaminants and supports the formation of a clean, stable passive surface. This makes it a valuable finishing process for stainless steel components where cleanliness, durability and corrosion resistance are important.

Why select stainless steel cleaning for your needs?
Stainless steel cleaning provides an effective way of treating components following manufacturing and fabrication processes. The process involves thorough cleaning, chemical treatment, rinsing, drying and inspection to achieve a clean and consistent finished surface.
Passivation is suitable for a wide range of stainless steel components, including precision-engineered and machined parts, as well as fabricated components and assemblies. It can also form part of a wider finishing process where additional surface preparation is required.
The appropriate treatment depends on factors including the stainless steel grade, the condition of the surface and the requirements of the finished component. Where more substantial contamination, scale or weld-related oxidation is present, pickling or another preparatory treatment may be required before passivation.
At C & W Finishings, we can discuss your requirements and advise on the appropriate finishing process for your stainless steel components.
The benefits of stainless steel cleaning
Stainless steel cleaning helps maintain the material's natural corrosion resistance by removing surface contamination and supporting the formation of its protective passive layer.
The process is particularly useful where clean, consistent stainless steel surfaces are required. As passivation is a chemical surface treatment rather than a conventional coating, it does not introduce a separate coating thickness onto the component, making it suitable for precision applications.
From machined components to fabricated stainless steel parts and assemblies, passivation can provide an important final finishing stage for components destined for demanding service environments.
Where suitable, sand-blasting can also be used as a surface preparation process to help remove surface contaminants and prepare components for subsequent finishing treatments.
