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.
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].
Terracotta Laser Cleaning
Terracotta cleaned without thermal shock cracking — Fe₂O₃ hot-spot risk managed at 1.0–3.5 J/cm² to keep gradients safe. Bay Area on-site service.
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.
Walnut Laser Cleaning
Walnut finish and fire residue removed without charring — widest common hardwood process window at 3.68 J/cm² makes cleaning reliable. Bay Area service.

Frequently Asked Questions
How is antique cash register used on Antique National Cash Register?
Laser cleaning removes alkyd paint, rust, and nickel-plating oxidation from National Cash Register brass and steel surfaces in 1–3 passes. Surface temperature stays below 120°C — critical for preserving 1890s–1910s NCR ornamental brass castings per ASTM B36 sheet brass tolerances. Original nickel-plated steel drawer frames clean without delamination because laser cleaning is selective to the contaminant layer, confirming SSPC-SP 1 solvent-clean equivalence on exposed steel hardware.
What laser cleaning settings work best for Antique National Cash Register?
The energy level is kept low enough to lift old finish, tarnish, and grime from this antique National 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.
What does Antique National Cash Register laser cleaning cost?
Antique National Cash Register laser cleaning typically costs $350–$900 depending on register size, contaminant depth, and surface count. Brass-only registers with minor oxidation run 2–4 hours; heavily corroded units with original nickel plating require 4–8 hours. Pricing reflects OSHA 29 CFR 1910.94 compliant fume extraction setup and post-clean ASTM E1444 surface verification — included in Z-Beam project quotes rather than billed separately.
How to choose a laser cleaning service for Antique National Cash Register?
Ask any service provider to show you a before-and-after photo of a similar job — brass engraving or nickel-plated steel — before committing. A provider with the right experience will start with a test patch on a hidden surface and show you the result before touching the register face. Also ask about turnaround: a full NCR register with multiple surfaces typically takes two to four hours on-site, so same-day completion is realistic. Providers who quote.
