Brass hardware looks great when it's new. Then the fingerprints show up, the shine fades, and some handles turn a murky brown. Before you reach for a harsh cleaner, stop for a moment. The best way to clean brass hardware depends on one thing: whether your brass is coated or bare.

This guide explains how to tell the difference, how to clean each type safely, and how to polish brass hardware without damaging it.

Why Brass Gets Dull

Brass is a mix of copper and zinc. When it meets air, moisture, and skin oils, the surface slowly darkens. That's tarnish, and it's normal. It doesn't mean your hardware is ruined.

• Air and humidity: Cause gradual darkening.
• Skin oils: Leave fingerprints and spots.
• Cooking grease: Creates a sticky, cloudy film.
• Steam and water: Can cause brown or green marks.
• Harsh sprays: May leave stains or a patchy finish.

Step One: Find Out If Your Brass Is Lacquered

This is the step most people skip, and it matters most. Many cabinet handles carry a clear protective coating called lacquer. It keeps the brass from tarnishing, but strong cleaners can strip it.

For example, VigorousHome describes its brushed brass and antique brass handles as solid brass with a baked clear lacquer on top. Handles like that need only gentle cleaning.

Here's how to check your own:

• Smooth, glossy surface that stays shiny: Likely lacquered.
• Dull, patchy, dark in spots: May be unlacquered or have worn lacquer.
• Magnet sticks: May be brass-plated steel rather than solid brass.
• Magnet doesn't stick: Probably solid brass.

If you're not sure, treat it as lacquered. Start gentle and only move up if needed.
