Laser cleaning is a process in which a specific frequency of light is used to target surface rust, contaminants, and residues. It was originally an industrial tool used on production lines. Content creator Workshop Rebuild is an early adopter of using this technology for car-restoration purposes. With its precise ability to remove rust without damaging the metal substrate, this technology has the potential to save delicate restoration projects and can serve as a great all-purpose tool for removing contaminants and residues.
