Museum-Grade Restoration for a Numismatic Collector
Détail du cas
Restoration · Coins & Collectibles
A professional coin and relic collector needed to lift encrusted soil, oxidation and old adhesive from centuries-old coins, medals and small metal artefacts — without abrasive rubbing that could destroy patina, detail or resale value. A standard household cleaner was too aggressive; the work demanded precision.
ChallengeDelicate surfaces and fine engraving easily damaged by brushes or harsh chemicals; every piece one of a kind.
SolutionCompact ACMESONIC desktop Ultrasonic Cleaner, 40 kHz, 40 °C, short 3-minute Gentle cycles in distilled water with a mild solution, inspected piece by piece.
ResultNon-abrasive, museum-grade restoration, details preserved, satisfied collectors — and zero damage across the entire collection.
