What is the Oil Stain?
Oil stain is a complex mixture of hydrocarbons, esters, and additives. Its characteristics directly affect the difficulty of cleaning. The physical state of oil stains varies, including liquid (such as lubricating oil), semi-solid (like butter), and solid (like carbon deposits).
It has strong adhesion and permeability, allowing it to be adsorbed on metal surfaces and penetrate tiny cracks. Since oil stains are common on equipment or metal surfaces, long-term adhesion will damage the original coating.
To ensure the reliability of equipment operation and extend its service life, people typically clean and maintain it on a regular basis.
Typical Applications for Oil Removal
Oil stains often appear in scenarios where oil contacts the surface of an object or condenses after volatilization.
- When cooking in the kitchen, cooking oil evaporates into oil smoke at high temperature, and condenses on surfaces such as stoves and walls after cooling. Oil in food residues also easily adheres to.
- In mechanical maintenance or industrial production, lubricating oil and hydraulic oil can adhere to tools, parts, and the ground due to equipment leakage or operational splashing.
- When the car engine is running, oil vapor may overflow from the cylinder gap and condense on the engine’s surface after cooling.
- In the exhaust duct of the back kitchen of the catering industry, the long-term accumulation of oil smoke will also form thick and sticky oil stains.
- In addition, oil mist particles in the air often combine with dust and deposit on the surface of equipment or objects to form a thin layer of oil stains.
These oil stains are typically formed through physical attachment, volatilization, condensation, or chemical reactions.
Laser Oil Removal Solution
HANTENCNC has developed pulse laser cleaning machines with a power range of 200W to 1000W for this market application.
For oil removal, we recommend models with a power range of 300W to 1000W.
Oil is commonly found attached to metal surfaces, such as industrial processing parts, castings, metal connectors, and large equipment. We prefer to use a multi-mode laser source to maximize the protection of the metal substrate.
- For thin layers of oil, use a 300W-5mj laser source. If you need to improve efficiency, choose a 500W-15mj laser source.
- When encountering heavy sludge, it is recommended to use physical means (such as shoveling) and use a 500W-15mj or 1000W-15mj laser source.
- For precision parts, a 500W-50mj or 1000W-50mj laser source can be used to ensure zero-damage cleaning.
Wide Adjustable Range: adapts to the cleaning needs of different materials and pollution types.
Diverse Power Configuration: provides a variety of power range options, covering 200W-1000W.
Adjustable Cleaning Line Width: can be freely set according to working conditions to improve cleaning efficiency and accuracy.
Built-in Process Database: can automatically recommend cleaning parameters according to material type. The operations are more convenient.
Various Models: including trolley case type, backpack type, portable (Seagull series, Seal series. They can meet the needs of various scenarios.
Pulse Laser Oil Cleaning VS Traditional Oil Cleaning
Pulse laser oil cleaning has significant advantages over traditional oil cleaning methods:
- It achieves extreme cleanliness without damaging the substrate.
- It is almost irreplaceable in scenarios with extremely high cleaning requirements.
- No chemicals are required during the cleaning process, and no wastewater pollution is generated. This is in line with the trend of environmental protection and sustainable development.
- Controllability and automation are easier to integrate into modern intelligent production lines. When used frequently for a long time, the overall cost is also lower.

Laser Oil Stain Removal Applications
Automotive Parts
Before welding the car body, the lubricant at the joint of the plate needs to be removed. This ensures the quality of welding.
Automobile gears and bearings must also be free of oil when replaced to ensure normal operation after the engine is started.
Aerospace
Before the plane takes off, the turbine blades, gear transmission, and other parts need to be cleaned. Oil and grease residues must be thoroughly removed to ensure flight safety.
Rail Transit
Workers need to clean the oil and old coatings generated by bearings, axle boxes, and other parts on the track every day. In the face of large-scale cleaning, manual efficiency is low, and parts are easily damaged. Laser cleaning offers the advantages of non-contact operation, environmental protection, high efficiency, and minimal damage to the substrate, which is particularly important in this scenario.

FAQs of Laser Oil Cleaning Machine
What types of oil stains can be removed by laser cleaning?
Industrial lubricants, anti-rust oil, hydraulic oil, cutting oil, kitchen oil stains, sebum, and other organic pollutants.
Laser cleaning is particularly suitable for stubborn oil stains on metal, glass, and stone surfaces.
Do you need to wash or wipe after cleaning?
No. Laser cleaning is a dry cleaning method. It does not require water and chemicals, and will not leave residual liquid stains. The surface is clean and tidy after cleaning. You can directly carry out subsequent processes such as spraying, electroplating, welding, etc.
Do the cleaning speeds of different oil stain thicknesses have the same speed?
It is different. The thicker the oil stain, the stronger the viscosity. The higher the laser energy density, the longer the cleaning time will be. We will provide customers with parameter testing and cleaning solution optimization suggestions to ensure both efficiency and effectiveness.
Will there be smoke or odor during laser cleaning?
A small amount of smoke and odor will be generated. You can deal with it through the matching smoke extraction and purification system. This can ensure the health of operators and meet environmental protection standards.
Can it clean high-reflective materials such as brass, copper, and aluminum alloy?
Yes. Our pulse laser cleaning machines are suitable for a variety of materials. Equipped with special parameter templates for high-reflective materials, it can safely and efficiently clean aluminum, copper, and other materials.
