Laser Cleaning FAQ: Your Questions Answered

If you are new to laser cleaning, you probably have questions. This complete FAQ brings together the most common ones, with clear answers and links to deeper guides on each topic.

Key takeaways

Laser cleaning removes rust, paint, graffiti and coatings with light, no chemicals or grit.
It is safe with the right controls, and suitable for heritage and occupied sites.
One machine cleans stone, metal, timber and painted surfaces.
It costs more to buy than blasting kit but far less to run.

How does laser cleaning work?

Laser cleaning works by firing pulses of light at a surface so the contaminant absorbs the energy, heats instantly and lifts away, while the clean material beneath reflects the energy and is preserved. It is non-contact and chemical free.

For the full explanation, see how laser cleaning works.

Is it safe and what can it clean?

Laser cleaning is safe with the correct eyewear, extraction and a controlled area, and it cleans stone, brick, concrete, metal, timber and painted joinery, removing rust, paint, graffiti, soot and growth. One machine handles the range.

How does it compare to other methods?

Compared with sandblasting and chemicals, laser cleaning is more precise, cleaner and gentler on the surface, with lower running costs, though it costs more to buy. It avoids the waste and substrate damage of the older methods.

Frequently asked questions

It fires pulses of light at a surface so the contaminant absorbs the energy, heats instantly and lifts away, while the clean material beneath reflects the energy and is preserved. The process is non-contact and chemical free.

Yes, with the correct eyewear, extraction and a controlled work area. The beam is a Class 4 laser, so safety controls are required, but the process is chemical free and suitable for occupied and heritage sites.

Rust, paint, varnish, graffiti, soot, oil, coatings and biological growth, from stone, brick, concrete, steel, iron, aluminium, timber and painted joinery. One machine handles the full range by adjusting the settings.

LaserStrip FLT-P machines start from £10,500 plus VAT for the 200W model, with 300W and 500W options. Running costs are low because the machine uses electricity only, with no abrasive or chemicals to buy.

For precision, surface preservation and cleanliness, yes. Laser cleaning removes only the contaminant with minimal waste, while sandblasting erodes the surface and creates heavy waste. Blasting can be faster on large rough areas.
