Bronze Laser Cleaning
Bronze statues look green and crusty at the start. A stopped pass leaves the intended hue, not a raw wound where the crust once sat.


An antique Evinrude outboard propeller carries marine growth, paint, and rust on a bronze or iron blade. Leading edges, the hub bore, and heat that can soften a thin blade or take the factory look with the crust are what a careful operator watches.
Short 2YvfFE4f3Lk shows pulsed laser clearing barnacles, marine corrosion, and old paint from an antique Evinrude outboard propeller without grit.
The clip is a 33-second pulsed-fiber demo on a single propeller. You see barnacle shells, marine crust, and old coatings leave aluminum and bronze blade faces while the hub geometry stays in frame. It is footage proof that contactless cleaning can reach marine soil on a vintage outboard propeller, not a timed quote for every boat yard.
Antique Evinrude blades are thin and often irreplaceable, so any method that bites the metal is hard to undo. Media blast and chemical dips remove metal along with soil. The Short shows the laser path clearing crust while blade edges and pitch lines stay readable, which is the restoration goal when the casting itself is the spare.
Both alloys share the frame, but they do not share one safe energy habit. Aluminum faces heat faster and want a quicker traveler; bronze can take a steadier pass for thicker oxide and verdigris. Operators should change speed and coupon each alloy family instead of locking one setting for the whole propeller.
Use the Short to see the cleaning sequence and the soil leaving the part, then coupon the next alloy before production. A copied recipe can mark soft faces even when the buildup looks familiar. Match scrap of the same metal family first, especially on paint-coated marine hardware.
