In the field of cultural heritage protection and cultural relic restoration, laser cleaning technology has gradually emerged in recent years and has become an efficient, precise and environmentally friendly cleaning method. This article will explore the necessity of cultural relic restoration, the application, advantages and laser cleaning solutions for cultural relics restoration.
Why do antiques need to be cleaned?
1. Necessity
Most of the cultural relics unearthed from Sanxingdui have experienced a long history, and their texture is very fragile. There are more or less pollutants on the surface, such as rust, mold, dust, and insect spots. It is these historical marks that have broken its original appearance. Over the years, in order to find its original appearance in the memory of history, cultural relic staff have carried out various restoration work, including cleaning of pollutants on the surface of cultural relics.
2. Traditional cleaning
For the surface cleaning of cultural relics, the cleaning methods commonly used by staff now include mechanical cleaning and chemical cleaning. The cleaning of cultural relics (water washing, dry cleaning, dry wiping, air drying, mechanical dust removal) mainly relies on the operator’s skilled experience and techniques, , and uses chemical drugs to solve it. However, in this process, cultural relics will inevitably be corroded by chemicals, causing discoloration, peeling, and even surface penetration. After all, there are certain risks in cleaning cultural relics. Even cleaning cultural relics with confidential instruments will cause damage to the surface of cultural relics.
So in the restoration of cultural relics, how to choose and use a cleaning method that is harmless to cultural relics and convenient and efficient to remove rust and pollutants is particularly important.
Advantages of laser cleaning solutions
Laser cleaning is a dry, gentle and highly free advanced restoration process for cultural relics restoration. By using the characteristics of laser beams and setting different laser parameters, staff can distinguish between pollutants and the surface materials of cultural relics, selectively and accurately locate the surface materials of cultural relics and the sediments, coverings, and oxides attached to them, and vaporize and evaporate them with laser beams, so as to not harm cultural relics but remove pollutants.
- Gentle light wave cleaning;
- Will not wear delicate surfaces;
- No contact/no impact—only the laser contacts the surface, with little side effects on the artifact itself;
- No need to use or produce chemical reagents, abrasives, water, dust or residues that can cause long-term damage to the surface;
- Completely dry operation—no water or liquid that can cause wet damage and erosion;
- Easy to use and precise adjustment;
- High reliability, low maintenance cost, low cost of use;
- Clean and environmentally friendly, no secondary pollutants, runoff and dust that are harmful to people or the environment.
Which artifacts can be “renovated”?
Laser cleaning can clean the surfaces of artifacts made of different materials such as stone (marble, jade), metal (bronze, iron, etc.), oil paintings, ceramics, sheepskin, paper, ivory, silk textiles, wood, etc., and ensure no residue or damage.

4. Solution
The cleaning of bronze artifacts is one of the main problems currently faced in the protection and restoration of cultural relics. Although traditional chemical cleaning methods can remove rust, they damage the surface details of bronze artifacts. Advanced laser technology can clean bronze artifacts non-destructively and harmlessly. By adjusting the laser wavelength and power, it can efficiently solve the old problems that other cleaning methods cannot solve.
Summary
With the continuous advancement of technology and the expansion of its application scope, laser cleaning will play an increasingly important role in the field of cultural relic protection and restoration. By reasonably implementing laser cleaning solutions, it can not only effectively protect cultural heritage, but also continue the memory of history and leave valuable cultural wealth for future generations.
