Introduction of Laser Rust Removal
Laser rust removal is also known as the laser cleaning and laser derusting. It is a new technology based on the interaction effect between laser and matter. Unlike traditional mechanical cleaning methods, chemical cleaning methods, and ultrasonic cleaning methods, laser cleaning technology does not require any CFC organic solvents that destroys the ozone layer. Moreover, it has the advantages no pollution, no noise, no harm to human body, high efficiency, fast speed, no pollution to the environment, and wide adaptability. It is a “green” cleaning technology that is very suitable for large-scale and large-volume rust removal. And because of its excellent rust removal effect, it has received more and more extensive market and attention. At the same time, laser cleaning technology is strongly supported by the state and has been included in the 2025 industry catalogue.
Why Choose Laser Rust Removal Instead of Other Cleaning Methods?
As we all know, metal plays an essential role in people’s daily life and in major manufacturing industries. But when iron reacts with oxygen and moisture, some metal surfaces will get rust. Therefore, metal rust removal has become a major problem that people face. In order to continue metal reuse plans, the rust must first be removed. However, depending on the amount, area, as well as application of the metal, the rust removal method used is also different. How should we remove rust from metals without damaging the metal itself? Below I will take you on an exploration.
Manual rust removal
Manually removing rust off metal refers to grinding with wire brushes, sandpaper, files, and scrapers to remove the rust on the metal surface. This method is the most primitive and most commonly used method to remove metal rust. This method is simple, easy to implement, and with low cost. But the work efficiency is extremely low and the labor intensity is high.
Chemical rust removal
Chemical rust removal is more common in home rust removal, such as by using white vinegar, soda, acid, lemon juice cream, potatoes, etc. to remove rust. The principle is to dissolve the metal rust in the acid- use the acid to react with the rust (oxide) on the metal surface. The advantage of this method is that it is safe and non-corrosive. It does not produce harmful substance, and can be easily operated even at home. And it is great for rust removal of knives, shovels, small workpieces, metal parts, and other small rusty items.
Flame rust removal
Flame rust removal is mainly to shovel off the rust layer on the surface of the substrate. Then bake or heat it with flames, and use a power wire brush to clean it. It is suitable for derusting the steel surface or castings with a certain thickness. However, this method cannot completely remove rust. More often, it removes old oxide skin and generates new oxide skin. Therefore, you should clean immediately for the second time with other rust removal tools. Besides, it has the pros of low production efficiency and high energy consumption.
Shot blasting
Shot blasting is the most suitable derusting method for most kinds of coating materials. This method is mainly composed of particle jet erosion to achieve surface cleaning and suitable roughness. On the one hand, the shot blasting derusting method has high efficiency and good derusting quality. But on the other hand, its waste is not recyclable and it is troublesome to clean up. Thus resulting in the serious environmental pollution. So it has been gradually restricted in use recently.
Laser rust removal (☆)
Laser rust removal also known as laser cleaning. It refers to the use of high-frequency and high-energy laser pulses to irradiate the surface of the workpiece. In order to effectively remove surface attachments or surface coatings at a high speed without additional chemicals. Moreover, the power of the laser beam also determines the thickness and range of rust removal. The higher the laser power, the more obvious the rust removal effect of the machine. Laser cleaning can remove various types of pollutants on the surface of various materials, and achieve a derusting effect that cannot be achieved by conventional derusting methods. Moreover, it can also selectively remove the pollutants on the surface of the rust material without damaging the surface of the material.
From the above five metal rust removal methods, we can see that laser metal rust removal is currently the most thorough and fastest solution. It is not only safe and pollution-free, but also has wider applications. So it gradually replaces other traditional rust removal methods and becomes the most important metal rust removal method. This is why people are increasingly favoring and choosing laser rust removal.
4 Ways of Laser Rust Removal
Above we briefly introduced the principle of laser rust removal. Next, I will take you to further understand other aspects of laser rust removing. First of all, according to different materials, it includes the following four types:
1. Laser dry cleaning
That is to use pulsed laser direct radiation decontamination. Lasers are divided into continuous lasers and pulsed lasers. Under the same power, pulsed lasers can achieve higher energy output. However, the price of pulsed laser is much higher than that of continuous laser. Therefore, now the domestic mainstream laser rust removal machine ( laser descaling machine) almost use continuous laser with the laser power of 1000w to 2000w.
2. Laser + liquid film
Deposit a layer of liquid film on the surface of the rusty object. When the laser is irradiated on the liquid film, the liquid film is heated rapidly to produce explosive vaporization. Then the explosive shock wave loosens the dirt on the surface of the substrate.
3. Laser + inert gas (☆)
While the laser is irradiating, the dirt is blown away from the surface with an inert gas to avoid re-contamination and oxidation. The inert gas mainly uses nitrogen, which not only blows away dust, but also cools the temperature of the laser head. Thus it effectively protects the laser lens and prolongs the life of the lens. In addition to nitrogen, argon is also acceptable. If there is no inert gas, it is also possible to use an air pump with oil-water filter in the short term. But in a word, you’d better develop a good habit of using gas.
4. Laser + chemical rust removal
Firstly, using laser to loose the dirt. Then adopting non-corrosive chemical reagent to remove off rust.
Among the above 4 common ways, “laser + inert gas” is currently the most main laser cleaning solution. Especially the combination of handheld laser rust remover with inert gas.

And the waste material does not pollute the environment. Besides, it can also be operated remotely, which effectively reduces the health damage to the operators.
6. Historical artifact cleaning
In addition to metal derusting, laser cleaning technology is also used in the cleaning of stone, bronze, oil paintings, ceramics, ivory cultural relics, textiles, and other cultural relics. For example, it can be applied to remove ink, stone deposits, stone grease and deposits, etc. Among them, laser clean stone cultural relics is the most advanced and mature.
Laser cleaning technology is a relatively mild cleaning technology. It has a good cleaning effect, little side effects, and is very friendly to the environment. However, if the laser energy is large or the parameter setting and operation is wrong, it may also cause damage to some fragile cultural relics. Therefore, it is generally not recommended to use this method to clean organic cultural relics.
