Bronze Laser Cleaning
Bronze patina preserved at 0.8 J/cm²; industrial bronze descaled at 5.8 J/cm² — same equipment, right parameters for the job. Bay Area on-site service.


Pulsed fiber laser cleaning restores an antique Evinrude outboard gas tank by safely removing heavy marine corrosion, old paint, and rust from steel while preserving original seams and hardware.
The laser energy level is calibrated to remove rust and corrosion from antique outboard motor parts without marking, pitting, or changing the surface below. Parts are checked visually and tactilely after cleaning to confirm the surface is undamaged. No abrasive contact and no chemical exposure means dimensional tolerances and surface finish are preserved.
Laser cleaning removes rust, paint, and marine corrosion without removing base steel — sandblasting removes material per pass and can thin already-corroded tank walls by 5–10% in a single session. Media blasting also obliterates factory stampings and paint-fill lettering common on pre-1940 Evinrude tanks. Chemical baths require 20–60 minute dwell times and generate hazardous waste under EPA 40 CFR Part 262 manifest requirements. Laser leaves factory seams, part numbers, and surface profile intact; typical tank.
Laser cleaning removes iron oxide rust, alkyd and enamel paint layers typical on 1920s–1950s Evinrude tanks, and marine biofouling from steel surfaces. Heavily corroded surfaces require multiple passes until bare steel is reached. The process achieves SSPC-SP 6 commercial cleanliness in most cases; SSPC-SP 10 near-white cleanliness requires additional passes and is available for parts that require a higher prep standard before coating.
The laser is calibrated to remove rust and corrosion from antique outboard motor parts without marking or changing the surface below. Most jobs take one to two passes depending on how heavy the buildup is. The surface comes out ready for coating, welding, or inspection with no additional prep and no chemical residue.
