Antique National Cash Register Laser Restoration

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.

The energy level for ash is kept low enough to lift old finish, char, or weathering without scorching or cutting into the wood grain. Most furniture and millwork jobs take one careful pass — the wood comes out looking like fresh, raw material without any abrasive contact. Delicate carved details and thin veneers survive intact.

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.

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 multi-day timelines for a single piece may be using slower or less targeted methods.
