How to Clean Brass Like a Pro

Brass adds a timeless, elegant touch to homes — from faucets and handles to cabinet pulls, frames, and light fixtures. But for cleaning professionals, it can also be one of the trickiest materials to maintain. Over time, brass tends to oxidize and tarnish, losing its natural luster and turning dull or greenish.

Let’s talk about how to restore that brilliant shine the right way — without harsh chemicals — and how to keep it from tarnishing again.

Step 1: Identify if It’s Solid or Plated Brass

Before cleaning, take a moment to identify whether the fixture is solid brass or brass-plated.

Solid brass usually feels heavier and has a warm, golden tone, while brass-plated pieces tend to be lighter and more uniform in color.

Why it matters: brass-plated finishes have only a thin layer of brass on top, so avoid abrasive scrubbing that could strip the coating.

Step 2: The Safe and Effective Way to Clean Brass

When it comes to professional cleaning, safety and surface preservation are everything.

That’s why we recommend Scum Bum — a non-toxic, acidic cleaner formulated with glycolic acid that cuts through soap scum, hard water stains, and mineral buildup without damaging metal finishes.

Scum Bum is perfect for:

• Bathroom and kitchen faucets

• Shower heads and handles

• Decorative brass fixtures

• Light switches, knobs, and towel bars

To clean:

1. Spray Scum Bum directly onto the brass surface.

2. Let it dwell for a few minutes

3. For brass, use more than just a soft cloth — a toothbrush, small brush, or our White or Walnut Pad works great for detailed areas.

4. Rinse thoroughly and dry completely with a clean towel.

Avoid scrubbing with abrasive pads or steel wool — they can scratch and strip the finish.

Step 3: How to Prevent Brass From Tarnishing

Cleaning brass is only half the job — preventing oxidation is what keeps it looking new longer.

Here are the pro tips for keeping brass bright and spotless:

• Optional protection: After cleaning, you might notice that some brass fixtures don’t have a protective coating. While applying lacquer isn’t part of your cleaning routine, you can mention to the homeowner that professionally lacquering the brass helps prevent tarnish and keeps the shine longer. Un-lacquered brass oxidizes faster, even with regular maintenance.

• Dry thoroughly: Always dry brass completely after cleaning. Even small water droplets can lead to spots or early tarnish..

• Ensure the cleaner you use is appropriate for brass finishes: Stay away from strong chemicals or abrasives — they strip the surface and destroy protective finishes.

Step 4: Regular Maintenance for Professionals

For cleaning businesses, incorporating brass care into your maintenance checklist is a simple way to add value to your service.

• Recommended routine:

  • Weekly: Clean brass fixtures with Scum Bum to remove soap scum, fingerprints, and light tarnish before buildup hardens.

  • Monthly: Do a slightly deeper clean to maintain shine and prevent oxidation.

  • Annually: Inspect for signs of wear or lacquer damage and inform the homeowner if professional refinishing might be needed.

  This routine not only protects surfaces but also demonstrates your team’s attention to detail — a mark of true professionalism.

Final Word

Brass may seem high-maintenance, but with the right cleaner and preventive care, it can stay bright for decades.

Scum Bum’s non-toxic, biodegradable formula gives you the power to remove mineral buildup and tarnish safely — no harsh fumes, no scratched finishes, and no wasted time.
