Graffiti and weathering come off stone without water, chemicals or loss of surface detail.
Typical industries: Building restoration, stone carving maintenance, historical architecture
Recommended machines: 200W–800W medium-power series
Graffiti, weathering stains and biological growth had to be removed from stone facades.
Challenge: Pressure washing caused water intrusion and runoff pollution; chemical cleaners risked discolouration or etching.
Machine used: 300W Trolley Series
A maintenance bay needs one machine that covers most of the week's work: rust off incoming steel, residue out of a die, paint off a bracket, and occasionally the same job outside in the yard.
Rust and coating on a bridge girder, a transmission tower, a ship's inner hull or a scaffolded facade cannot be brought to a cleaning bay.
Photographs and a description are enough to start. A physical sample gets you before/after images, video and the exact parameters — free either way.
