Cleaning Antique Brass Without Destroying Patina
Conservative cleaning techniques that protect value.
Over-polishing destroys more antique value than dirt ever does.
Identify the finish first
Lacquered brass, unlacquered brass and brass-plated steel all behave differently. A magnet tells you quickly whether you are dealing with plate over steel — in which case aggressive polishing will go straight through the plating.
Conservative approach
- Start with a dry microfibre cloth.
- Move to warm water with a drop of mild detergent.
- Dry completely and immediately.
- Use metal polish only on unlacquered brass you genuinely want brightened.
When to leave it alone
Even patina on a documented antique is usually worth keeping. If you are unsure, ask before you polish — it cannot be undone.
