About Laser Cleaning

Laser Cleaning technology finds its roots in laser marking machines. It uses high energy light pulses to ablate a contaminant from a substrate, reducing secondary waste to nihil. 

Due to its basic physics, Laser Cleaning allows for extremely precise cleaning. It's human and environmentally friendly and has a very low operational cost.

How it works

Laser cleaning is a versatile, flexible technology allowing for very precise cleaning without secondary waste, consumables or air movements.

The pulsed lasers are best to be imagined as bullets of light being shot at a surface. The contaminant will absorb the light that is then reflected on the substrate below. Both layers release each other and the contaminant is extracted immediately - avoiding any atmospheric contamination. 

During the process, the substrate is not significantly heated, nor is it damaged. 

PVD coated drills

PVD Coating

Using our laser cleaning machines allows for removal of PVD coating without damaging the substrate and improves re-coating results afterwards.

Tank cleaning

Flash rust removal inside of tanks after high pressure water cleaning. Drastically reducing waste cycle and allowing for thorough inspection.

Mould cleaning

Safe cleaning of your valuable moulds. No secondary waste or damage to the substrate - safe for high gloss finish and base materials like e.g. aluminum, steel or Ampco alloys.

glass coating removal

Glass coating removal

Laser allows for very precise selective coating removal, also on glass!

turbine cleaning

Turbine cleaning

Laser has proven to be the best technology to clean turbine parts without damaging the substrate, compared to glass, sand or dry ice blasting.


Process contamination


Removal of product rests such as e.g. silicone, grease, ...



Laser cleaning is used not only to clean aluminum substrates with contaminants like coating or process contaminants on them. It also is the best surface preparation technique for e.g. adhesion improvement.

carbon steel rebar

Carbon steel

Carbon steel is a common substrate cleaned with laser technology. We're capable of removing flash rust, oxides, grease, etc. without heating the substrate or changing its characteristics.



Bronze, or a bronze-copper alloy can be cleaned and treated with laser cleaning without damaging the substrate. Depending on the pulse profile used, one can either remove the patina or leave it untouched and just remove the contaminant.

copper plating


One of many substrates that are excellent to be cleaned with laser. Depending on the pulse shape used, the cleaning can reach different depths.

stainless steel building

Stainless steel

Stainless steel is one of our favourite substrates, because of its reflective characteristics. Think about tank cleaning, process contamination removal, weld cleaning, weld preparation, etc.

super alloy

Super alloys

Super alloys are used in many applications. Most famously known to be used in turbine parts. Laser cleaning allows for thorough cleaning without damaging the substrate or changing its characteristics.

Although we prefer metals, it can be virtually anything. As long as it can withstand heating and it should have some reflective capacity, it is worth testing.


Flash rust

Thin layers of rust disappear at high speeds up to 15 m2 per hour! Send us some pictures of your project to assess it correctly.

coating removal


Coatings come in all colours and varieties imaginable; making it a challenging but fascinating application. We have cleaned many types of coatings, in different thicknesses going from less than 100 microns to over a 1000. Don't worry about the colour, it's rather the ingredients of which the coating is built that influence success or speed.



Laser is the perfect tool to remove toxic contaminants. There is no secondary waste, no turbulence thus a highly controllable process in combination with good suction.



Resin Transfer Moulding is a process well known in aerospace and other carbon production industries. After a number of production cycles, the resin tends to build up on the mould. Cleaning this contaminant with laser is fast and safe for the mould.


Weld cleaning

Removing oxides after welding, without using chemicals. Laser cleaning also allows for weld preparation and drastically decreases the number of imperfections in the weld.
