Industrial metal degreasing process

Industrial chemical degreasing is an essential step in the preparation of metal parts. It effectively removes oils, greases, machining residues, and other contaminants that could compromise the quality of subsequent treatments or assemblies.
In addition to chemical stripping, degreasing ensures a clean, sound surface that is ready for the next stage of the industrial process.
What is chemical degreasing?
Chemical degreasing relies on the use of specific chemical baths, selected based on the type of metal, the nature of the contaminants (mineral oils, synthetic oils, heavy greases, etc.), and the requirements of the downstream process. The goal is to dissolve and remove the greasy substances present on the surface of metal parts. Unlike simple cleaning, chemical degreasing works deep down and ensures a perfectly clean and reactive surface.
A chemical degreasing process suitable for industrial metal parts
WIPELEC performs chemical degreasing on a wide variety of industrial metal parts, regardless of their shape or complexity:
- Machined mechanical parts
- Industrial components
- Small to medium-sized runs
- Technical parts requiring precise machining


The processes are adjusted based on:
- The type of metal
- The level of clogging
- Requirements for the subsequent treatment (pickling or passivation)
Types of treatments offered
Oxygen-based degreasing
This treatment removes all traces of grease, oil, or contaminants from parts. It is essential for equipment intended for use in oxygen-rich environments (such as the medical and aerospace industries), where even the slightest impurity can pose a risk of reaction or ignition.
Degreasing and neutralization of plastics
Plastic parts are cleaned to remove manufacturing residues and then neutralized to prevent any chemical reactions. This treatment ensures a clean, stable surface that is compatible with demanding technical environments.
Degreasing, pickling, and passivation of stainless steel
This treatment restores all of the stainless steel’s mechanical and sanitary properties:
- Degreasing: removal of surface contaminants
- Stripping: removal of oxides and impurities after welding or machining
- Passivation: the formation of a protective layer that enhances corrosion resistance
Degreasing, pickling, and passivation of copper-based materials
- Suitable for copper alloys (copper, brass, bronze), this process removes residues and oxides, improves conductivity and durability, and protects parts from premature oxidation.
Degreasing and stripping of aluminum
Modified atmosphere packaging
After processing, the parts are packaged in a controlled atmosphere to prevent recontamination. This process ensures long-lasting cleanliness until installation or final use, particularly for demanding industries (medical, high-tech, etc.).
