Owning a set of beryllium copper golf clubs means you appreciate the classic feel and timeless look of one of golf's most iconic materials. Getting them clean and keeping them in top shape isn't difficult, but it does require a different approach than cleaning standard steel or titanium clubs. This guide will walk you through everything, whether you want to restore that stunning, raw copper shine or preserve the dark, distinguished patina that tells a story of rounds well-played.
First, Understand Beryllium Copper and Its Famous Patina
There's a reason players still hunt down old sets of PING Eye 2 or Cobra BeCu irons and wedges. The material is very soft, providing a buttery, responsive feel at impact that many golfers find is unmatched even by modern forged clubs. That softness is also what makes it unique to care for.
Over time, as beryllium copper is exposed to air and moisture, it develops a dark brown, almost chocolate-colored finish. This is called a patina. It’s a natural protective layer that forms on the surface of the metal, shielding it from further corrosion. Many golfers absolutely love this look. It’s a badge of honor, a sign that the clubs are well-loved classics.
Before you start cleaning, you have one big decision to make:
- Do you want to preserve the patina? If you like the dark, antique look, you’ll just need a gentle cleaning to remove dirt and grass from the grooves.
- Do you want to remove the patina? If you're chasing that bright, shiny, off-the-rack rose-gold look, you’ll need a deeper cleaning and polishing process.
There's no right or wrong answer, it’s purely about your personal preference. The good news is that even if you strip the patina off, it will naturally return over time as you use the clubs.
A Critical Note on Beryllium Safety
Let's get this out of the way, because it's the most important point of all. The element beryllium is toxic if its dust is inhaled. I want to be perfectly clear: cleaning your beryllium copper clubs with soap, water, and polish is perfectly safe.
The danger comes from creating fine airborne particles. You should NEVER do any of the following to your BeCu clubs:
- Grind them on a grinding wheel.
- Sand them with sandpaper or a power sander.
- Use a wire-wheel brush to try and buff them.
These actions can release beryllium dust into the air, which is a serious respiratory hazard. As long as you are simply washing, scrubbing with a non-metal brush, and polishing with a cloth, you are in no danger whatsoever. Now, with that important safety point covered, let's get to cleaning.
Gathering Your Cleaning Supplies
Your shopping list will depend on whether you’re doing a light clean or a full-on restoration. Here’s a breakdown of what you might need.
For a Gentle Clean (Preserving the Patina):
- A bucket
- Warm water
- Mild dish soap
- A soft-bristled brush (a nylon golf club brush or even an old toothbrush works great)
- Several clean, dry microfiber towels
For a Deep Clean (Removing the Patina):
You’ll need everything from the list above, plus your choice of one of the following polishing agents:
- Coca-Cola: Yes, really. The phosphoric acid in Coke is fantastic at eating away patina without being overly harsh on the metal itself.
- Dedicated Metal Polish: Products like Brasso or Nevr-Dull are classic choices. They are specifically designed to remove tarnish and restore shine to metals like brass and copper.
- Natural Acid Paste: A homemade paste of lemon juice (or white vinegar) and salt can also work wonders. The mild acid combined with the abrasive salt helps lift the oxidation.
The Step-by-Step Cleaning Process
Work on a surface you don't mind getting a little wet or dirty, like in your garage or outdoors. I recommend working one club at a time to really give each one the attention it deserves.
Method 1: The Gentle Patina-Preserving Wash
This is your go-to for routine cleaning after a round or for when you simply want to keep that beautiful dark finish looking clean and respectable.
- Prepare Your Soapy Water: Fill your bucket with a few inches of warm water and add a few squirts of mild dish soap. Give it a swirl to create some suds.
- Soak the Heads: Place your clubheads in the bucket, making sure to only submerge the metal part. Try to keep the ferrules (the black plastic piece that connects the head to the shaft) out of the water, as prolonged soaking can weaken the epoxy holding them together. CPLet them soak for about 5-10 minutes to loosen any stubborn dirt in the grooves.
- Scrub the Face and Grooves: Take one club out and use your soft-bristled brush to gently scrub the face and scorelines. Pay special attention to the grooves, which is where compacted dirt can affect spin and performance. The goal here is just to dislodge dirt, not to scrub away the patina.
- Rinse Thoroughly: Rinse the clubhead under cool, clean water from your tap or a hose. Make sure to wash away all the soapy residue.
- Dry Completely: This is a step many people rush, but it's really important. Use a microfiber towel to dry the entire clubhead, shafts, and grip. Any moisture left behind, especially on the face of a BeCu club, can lead to premature re-oxidation marks. Let them air dry for a bit before putting the headcovers back on.
Method 2: The Deep Restoration Clean
Ready to see that incredible rose-gold shine again? This process takes a little more time and elbow grease, but the results are truly satisfying.
First, perform all five steps of the "Gentle Wash" above. You need to start with a clean surface before you begin polishing away the patina.
Technique A: The Coca-Cola Soak
- The Setup: Find a container just deep enough to submerge the clubheads. A tall plastic cup or a small bucket works well. You only need to cover the heads themselves. Fill it with enough Coca-Cola (regular, not diet) to do the job.
- The Soak: Lean your clubs against a wall or chair so the heads are fully submerged in the Coke. Again, try to keep the ferrules dry. Now, walk away. Leave them to soak for several hours, or even overnight for a really deep clean. You may even see the patina literally flaking off into the liquid.
- Scrub and Rinse: After soaking, take the clubs out and give them a quick scrub with your nylon brush. Then rinse themExtensively with clean water to remove all the sticky, acidic Coke residue.
- Dry and Admire: Dry the clubs thoroughly with your towel. You should see a dramatic difference, with most if not all of the dark patina gone, leaving a beautiful matte copper finish.
Technique B: The Metal Polish Application
- Apply the Polish: If you're using Brasso, dab a small amount onto a clean, soft cloth (not directly onto the club). If you're using Nevr-Dull, which is a pre-soaked wadding, just tear off a small piece.
- Work in Sections: Pick a spot on the club, like the sole or a part of the cavity back, and begin rubbing the polish in small circular motions. You’ll see the cloth turn black almost immediately––that's the oxidation coming off. Good! It means it’s working.
- Be Patient: This method requires manual effort. Continue polishing the entire head, adding more polish to your cloth as needed. You are essentially buffing the oxidation off by hand. Spend a little extra time on any stubborn spots.
- Buff to a Shine: Once you've removed the patina, take a separate, clean microfiber towel andvigorously buff the entire clubhead. This will remove the polish residue and bring out that brilliant, warm shine.
Aftercare: Maintaining Your BeCu Clubs
Congratulations! Your clubs look fantastic. Now, how do you keep them that way?
If you've just restored the shine, that bright finish won't last forever, and that's okay! It's the nature of the metal. Every time it gets exposed to moisture and air, the patination process will slowly begin again. To slow it down:
- Wipe After Every Shot: Keep a towel handy during your round. A quick wipe-down after each shot, especially on damp days, makes a huge difference.
- Clean After Every Round: At a minimum, give them a quick gentle wash (Method 1) after you play to remove dirt and sweat.
- Use Headcovers: BeCu is a soft metal. Aside from preventing oxidation, headcovers do a great job of preventing the dings and scratches that come from "bag chatter" as your clubs jangle around.
Embrace the ever-changing nature of these clubs. Whether you keep them dark and mysterious or shiny and new, taking pride in your equipment is part of the fun of golf. It connects you to your gear and gives you one less thing to worry about when you're standing over a shot that counts.
