The ELASER-RHZ is Woodrow Scientific's portable laser cleaning system incorporating their patented, world-first reduced hazard zone (RHZ) eye-safe technology. In practical terms, RHZ collapses the laser hazard zone to a small area around the work itself — the operator does not need to seal off or evacuate the surrounding space before cleaning begins. No other laser cleaning manufacturer in the world offers this capability. Wood cleaning most commonly takes place in open workshops, heritage buildings, architectural settings, and public-facing sites: exactly the environments where conventional laser cleaning — which requires a fully sealed-off safety zone — is impractical or impossible. The ELASER-RHZ is what makes laser cleaning genuinely deployable in those settings. Woodrow Scientific provides full operator training with every system. RHZ technology is also available as an upgrade on the AutoLASE automated system, making it the only automated laser cleaner in the world capable of operating without an enclosure.

Both systems cover the full range of timber cleaning tasks: paint, lacquer, varnish and primer stripping; mould and biological contamination removal; heritage and period timber restoration including carved woodwork, oak framing and gilded panels; surface preparation for re-coating and bonding by ablating the compressed surface layer to improve adhesion; structural and building timber cleaning such as beams, cladding and decking; and wooden component cleaning in production workflows covering release agents and adhesive residues. The ELASER and ELASER-RHZ handle on-site and portable work; AutoLASE handles volume production. The right system depends on whether you need to go to the timber or bring the timber to you.

On price positioning: Woodrow Scientific is the European cost leader among comparable industrial laser cleaning machines, with competitive pricing achieved through in-house manufacturing efficiency rather than any reduction in quality. The more relevant cost comparison, though, is total cost of ownership. Laser wood cleaning carries no consumables, no blast media, no chemical disposal costs, and less rework from substrate damage. Those running cost advantages compound over time and typically make the TCO case compelling against traditional methods.

Yes — laser cleaning is proven effective on wood. The laser beam ablates the coating or contamination and stops at the base material. Unlike abrasive methods, which erode the softer spring grain along with the coating, or chemical strippers, which soak into the timber and raise the grain, laser cleaning lifts the contaminant without touching the wood beneath. It works across both hardwood and softwood, with power settings tunable to match substrate sensitivity — from delicate heritage limewash removal through to thick paint stripping. The range of what it removes is broad: paint, varnish, lacquer, mould, soot, biological contamination, and adhesive residues are all within scope. Conservation practice and independent research both confirm laser cleaning on gilded wood, polychrome panels, exposed timber framing, and wooden artefacts — it is an established method in heritage restoration as well as industrial applications.

Wood is more heat-sensitive than metal or stone, so settings must be dialled in carefully for each combination of wood type and coating. Power and pulse parameters need to be matched to the specific substrate — this is a genuine practical consideration, though not a fundamental limitation. It simply means taking the time to set up correctly, which Woodrow Scientific's operator training covers directly. Laser cleaning is also not suitable for timber that is structurally compromised by rot or active woodworm. The wood needs to be structurally sound before cleaning; the process removes surface contamination but will not repair a deteriorated substrate. Beyond those two points, the practical scope of laser cleaning on wood is broad — it handles the full range of coatings, biological contamination, and surface deposits that timber cleaning typically involves.

For most wood applications, yes — laser cleaning is the superior choice and can replace sandblasting entirely. Sandblasting erodes the softer spring grain faster than the harder summer grain, leaving a furred, over-textured surface that no finishing process can restore. On heritage timber, architectural woodwork, or any wood where the original surface character matters, that damage is permanent. Laser cleaning preserves grain, colour, and patina because the beam stops at the substrate. The honest edge case: for high-volume stripping of flat, non-heritage timber where surface character is irrelevant, sandblasting can be faster. However, the substrate damage it causes typically generates rework — re-sanding, additional finishing passes, material loss — that erodes the speed advantage when assessed over the full job. On total cost of ownership, laser cleaning carries no consumable costs (no blast media, no disposal) and less rework, so the overall cost comparison often favours laser cleaning even in cases where sandblasting appears faster upfront.
