Antique Cash Register Laser Restoration
Pulsed fiber laser cleaning restores the finish on an antique cash register by safely removing old paint, rust, and grime from detailed brass, chrome, and painted surfaces.
What This Video Shows
This detailed restoration shows pulsed fiber laser cleaning on an antique cash register. Layers of paint, oxidation, and grime are vaporized, revealing original shine and crisp details.
Equipment Used
- Pulsed fiber laser cleaning system
Related Materials
Brass Laser Cleaning
Brass tarnish and oxide removed without etching — 92% surface reflectance means cleaning speed controls the process, not power. Bay Area on-site service.
Cast Iron Laser Cleaning
Fiber laser cleans gray and ductile cast iron at 1.5 J/cm² — no graphite pullout, no blast media. Cal/OSHA §5155. Bay Area on-site or Netalux rental.
Cherry Laser Cleaning
Cherry tannin stains and finishes stripped at 0.8–1.9 J/cm² in one pass — 93% laser absorption means complete cleaning, no residue. Bay Area service.
Iron Laser Cleaning
Iron rust lifts selectively at 1.5–2.5 J/cm² — oxide absorbs 60–70% vs. 35% for bare iron, so cleaning stops at clean metal. Bay Area service.
Mahogany Laser Cleaning
Mahogany cleaned of mildew and old finish within the 1.5 J/cm² process window — tight but repeatable parameters deliver complete results. Bay Area service.
Slate Laser Cleaning
Slate cleaned safely with a mandatory pre-job test patch — absorption varies by cleavage angle, confirmed before each full cleaning. Bay Area service.
Carbon Steel Laser Cleaning for Rust and Mill Scale
Steel laser cleaning at 3.96 J/cm² produces passivation [2] and raises surface microhardness 4–13% [7] — no blast media, meets Cal/OSHA 5 mg/m³ PEL [4].
Tool Steel Laser Cleaning
D2 tool steel descaled without temper loss — inter-pass cooling to <40°C is mandatory and protocol-included for every cleaning. Bay Area on-site service.

Frequently Asked Questions
Does laser cleaning damage cash register engravings or paint?
At the energy levels used for ash, the laser lifts old finish and weathering without scorching or cutting into the wood grain. Thin veneers, carved details, and edge moldings survive intact — the process is gentler than orbital sanding on fragile surfaces. Each job starts with a low-energy test pass to confirm the setting is safe before full cleaning begins.
How does laser cleaning compare to chemical strippers on vintage cash registers?
For most Bay Area antique restoration jobs, laser cleaning costs $250–$350/hr all-in — and that includes zero chemical disposal fees, no post-clean rinse, and no masking. Chemical stripping adds $50–$150 per drum in disposal costs on top of the labor, plus a second clean to remove residue. On anything larger than a single part, laser comes out cheaper when you add up the full job cost.
What contaminants are removed from antique cash registers?
Laser cleaning removes oxide from ash without abrasive contact, chemicals, or heat damage to the surface. One to two passes is typical for most jobs, and the surface is ready for the next operation immediately after cleaning. No secondary cleanup, no media to dispose of, and no chemical handling required.
What process settings matter most when restoring Antique Cash Register?
The energy level is kept low enough to lift old finish, tarnish, and grime from this antique cash register without scorching or cutting into the brass, chrome, or painted surfaces. Most restoration jobs take one careful pass — the metal comes out looking like fresh, raw material without any abrasive contact. Delicate engravings and edge details survive intact.
