VAPOUR DEGREASING
Precision Industrial Component Cleaning
Our professional vapour degreasing services provide fast, reliable, and residue-free cleaning for manufacturers, engineering companies, fabrication businesses, and industrial suppliers throughout the UK. Using advanced Rotajet cleaning systems, we deliver consistent cleaning results for components requiring high standards of cleanliness before assembly, inspection, coating, plating, painting, welding, or further manufacturing processes.
What is Vapour Degreasing?
Vapour degreasing is an industrial solvent cleaning process that uses heated solvent vapour to remove contamination from components and metal parts. During the cleaning process, components are placed inside a sealed cleaning chamber where solvent vapour condenses onto the cooler surface of the part. As the solvent condenses, it dissolves oils, grease, machining residues, and contaminants before draining away from the component. Because the solvent vapour can penetrate intricate geometries, threads, blind holes, recesses, and internal passages, vapour degreasing is particularly effective for cleaning complex precision components that are difficult to clean using manual or water-based cleaning methods.
Benefits of Vapour Degreasing
Fast & Efficient Cleaning
The process provides rapid cleaning and drying times, helping reduce production delays and increase operational efficiency.
Residue-Free Finish
Components are left clean, dry, and free from contamination, making vapour degreasing ideal for applications requiring high cleanliness standards.
Excellent for Precision
Vapour degreasing is suitable for precision-engineered components with intricate features, fine tolerances, and difficult-to-access areas.
Improved Surface Preparation
Removing contamination helps improve adhesion, coating quality, and manufacturing reliability.
Consistent Cleaning Results
Automated vapour degreasing systems provide repeatable cleaning performance and improved process consistency compared to manual cleaning methods.
Reduced Moisture Exposure
Unlike aqueous cleaning systems, vapour degreasing does not leave water trapped inside components, making it particularly suitable for sensitive or intricate parts.

FAQs
Vapour degreasing effectively removes oils, grease, machining fluids, waxes, coolants, flux residues, and many industrial production contaminants.
Yes. Vapour degreasing is widely used for precision engineering and aerospace applications because it can clean complex components thoroughly while leaving a residue-free finish.
No. One of the main advantages of vapour degreasing is that components are left clean and dry immediately after processing.
For many precision cleaning applications, vapour degreasing offers advantages including faster drying, improved cleaning of intricate components, and residue-free results.
Industries including aerospace, automotive, electronics, engineering, fabrication, hydraulics, pneumatics, and manufacturing regularly use vapour degreasing processes.
