Laser Cleaning for Furniture Renovation
1.What is a pulsed laser?
Pulse laser cleaning utilizes high-energy laser pulses to irradiate the surface, quickly removing pollutants such as rust, paint, and oil through a combination of photothermal and photomechanical effects.
The pulse laser can release high peak power in a very short time, quickly vaporizing, fragmenting, or peeling off surface contaminants and achieving efficient cleaning while protecting the substrate to the greatest extent.
2. Advantages of pulsed lasers – better substrate protection
Non-contact cleaning: no need to contact the workpiece surface, avoiding scratches and physical wear;
Small thermal impact: high-energy short pulses act instantly, heat is concentrated, and the substrate is prevented from being deformed by heat;
No damage to the substrate texture and coating layer: very suitable for the furniture industry’s high requirements for “appearance retention”;
3.Typical pollutants and application scenarios of pulsed laser cleaning machines in furniture renovation
Pulse Laser Cleaning Machine for Furniture Renovation Industry
The Pollutions that can be effectively cleaned by laser cleaning machine as follows:
- Paint layer/varnish layer (used for wooden furniture renovation to remove old coatings)
- Carbonized layer (burned and carbonized areas on the wood surface)
- Mold spots and oxidation spots (mold spots on old wood or outdoor furniture or walls and floors)
- Rust, metal parts oxide layer (metal furniture or hardware accessories)
Typical Furniture Renovation Application Scenarios:
- Renovation of high-end solid wood furniture, such as removal of old paint on chair backs, tabletops, and carvings;
- Restoration of outdoor wood products, such as removal of mildew and carbonization on the surface of benches and garden furniture;
- Cleaning of metal decorative parts, such as rust removal of furniture handles, rivets, and other hardware;
- Classical furniture restoration: used to finely remove multiple layers of paint or surface pollution, retaining the underlying texture;
- On-site repair after a fire: smoke, carbonization, and oil pollution of furniture parts.
Laser Cleaning VS Traditional Cleaning
| Comparison Dimension | Laser Cleaning | Chemical Cleaning (Paint Remover) | Sanding/Sandpaper | Heat Gun + Scraper | High-Pressure Washing |
|---|---|---|---|---|---|
| Cleaning Principle | Pulsed laser vaporizes or removes surface contaminants | Solvent softens the coating | Physical friction removes layers | Heat softens paint for manual scraping | High-pressure water flushes away dirt |
| Cleaning Effectiveness | Precise and efficient, ideal for intricate carvings and detailed areas | Quickly softens paint, suitable for large areas | Even layer removal, best for flat surfaces | Effective for thick, multi-layer paint in small areas | Good for dirt/debris removal but poor for paint |
| Impact on Substrate | Non-contact, no damage | May corrode or penetrate wood | Can scratch surfaces | Risk of scorching or deformation | Wood may absorb water and warp |
| Environmental Impact | No waste liquid or chemical pollution | Toxic fumes and chemical waste | Generates dust | Produces smoke pollution | High wastewater output, difficult cleanup |
| Ease of Operation | Easy to use, supports single-person mobile work | Requires multiple applications, tedious | Labor-intensive, low efficiency | Technically demanding, slow | Heavy equipment, unsuitable for interiors |
| Safety | Follows laser safety protocols (goggles/suits/masks provided) | Strong chemical irritants, highly corrosive | High dust inhalation risk | Burn hazards, smoke irritation | Slippery surfaces, electrical risks |
| Applicable Scenarios | High-end furniture, detailed refurbishment, on-site cleaning | Initial paint stripping, large old furniture | Wood surface sanding/repair | Localized stubborn paint removal | Outdoor rough furniture cleaning |
| Typical Issues | Requires training for beginners | Heavy residue, severe pollution | Difficult for carvings/curves | Low efficiency, material risks | Risk of water damage to furniture |

FAQs of Laser Cleaning
Can the carbonized layer on the surface be removed after the fire?
In most cases, the laser cleaning machine can effectively remove the carbonized layer, with more than 90% of the carbonized layer being removed.
Laser cleaning is particularly suitable for removing carbonized layers, charred residues, oil stains, and other pollutants that accumulate after a fire.
By adjusting the laser power, frequency, and scanning mode, the laser cleaning machine can accurately peel off the contaminated layer while preserving the surface structure of the substrate, without causing thermal damage to the wood or metal materials.
For areas with severe carbonization or tightly bonded carbon layers, we recommend performing a localized test cleaning first. Based on the results, fine-tuning the parameters can help achieve optimal cleaning performance.
Is it safe to use laser cleaning on wooden furniture? Will it get burned?
It is safe. Our laser cleaning equipment uses pulsed laser technology, which produces a minimal heat-affected zone. By adjusting the cleaning intensity, it enables gentle cleaning without burning or damaging the wood grain.
It is suitable for removing water-based paints and dust from various types of wooden surfaces.
Additionally, not all paints used on wooden products are suitable for laser cleaning. Water-based paint has the best cleaning effect, and the cleaning effects vary depending on the color and type of paint.
Does laser cleaning have any odor? Will it increase the smell of fire residue?
Laser cleaning is a chemical-free, water-free, and contact-free cleaning method. Compared with grinding, spray guns, and chemical agents, it does not generate pungent odors or release secondary pollutant gases.
During the cleaning process, a small amount of carbon smoke gas may be generated, which can be collected and purified through a smoke exhaust system.
Does the Continuous Laser Rust Removal Require any Consumables? Are the Operating Costs High?
No consumables are required, and the operating cost is extremely low.
Laser cleaning does not require chemicals, dry ice, or sandblasting consumables. It only requires electricity supply, and the long-term use cost is much lower than traditional methods.
How efficient is the laser cleaning machine? How long does it take to clean a wooden cabinet?
The cleaning time of the laser cleaning machine depends on the surface area of the furniture and the thickness of the grease and dust. Generally, a 300W pulse laser cleaning machine can achieve a cleaning speed of several tens of centimeters per minute.
For a medium-sized cabinet, the time required may be approximately 30 minutes.
For light dust, the cleaning efficiency will be higher.
Can I repaint the wood surface after laser cleaning?
Yes. Laser cleaning does not leave residue or chemicals. After laser cleaning, the wood surface is clean, oil-free, and water-free, making it ideal for secondary painting.
Laser cleaning is particularly suitable for sanding, painting or spraying furniture during furniture renewal.
Is it suitable for on-site service?
Laser cleaning is very suitable for on-site service. We recommend using HANTENCNC’s backpack-style or trolley-style pulse laser cleaning machine. These equipment are lightweight and flexible, featuring battery power supply or outdoor generator compatibility, enabling operating stably in an environment without a power supply.
It is especially suitable for on-site furniture cleaning after fires and the furniture restoration industry.
