How to Make Golf Irons Black

By Spencer Lanoue
July 24, 2025

Giving your golf irons a sleek, custom black finish is one of the most satisfying DIY projects a golfer can tackle. Beyond just looking incredible in the bag, a black finish can reduce sunglare and give you a boost of confidence over the ball. In this guide, I’ll walk you through the entire process, from understanding the different types of finishes to the detailed, step-by-step instructions for getting that perfect, professional-looking result at home.

Why Go Black with Your Irons?

There's a reason you see tour players and serious amateurs with blacked-out wedges and irons. It’s not just about aesthetics, though that's a huge part of it. A deep black finish imparts a certain look - stealthy, modern, and serious. It makes the clubhead appear slightly more compact at address, which many players find helps them focus on the sweet spot.

From a performance standpoint, the biggest advantage is glare reduction. On bright, sunny days, the reflection off a standard chrome or satin iron can be distracting. A matte or satin black finish absorbs light instead of reflecting it, giving you a crystal-clear view of the ball and your alignment. It’s a small thing, but in a game of inches, every bit of comfort and focus helps.

Finally, there's the pride of craftsmanship. Having a set of irons you've customized yourself creates a unique connection to your equipment. You’re not just playing a stock set, you’re playing your set.

Understanding Your Options: DIY vs. Professional Finishes

Before you run to the hardware store, it’s important to understand the different ways an iron can be blackened. The method you choose depends on durability, cost, and whether you're willing to do it yourself.

Professional-Grade Finishes: PVD and DLC

The ultra-durable, premium black finishes you see on brand-new clubs from companies like Titleist (Vokey wedges) or TaylorMade are typically applied using Physical Vapor Deposition (PVD) or Diamond-Like Carbon (DLC). These are highly technical processes that occur in a vacuum chamber where vaporized microscopic particles of material bond to the surface of the steel. The result is an incredibly tough, thin, and beautiful finish.

This is not a DIY process. It requires expensive, industrial machinery. If you want this level of durability, you’ll need to send your club heads to a specialized golf club customization company. It provides the best possible finish, but it comes at a higher cost.

The Accessible DIY ROUTE: Cold Black Oxide (Gun Blue)

For the hands-on golfer, the most effective and popular DIY method is using a cold black oxide solution, often sold as "gun bluing." This isn't a paint or a coating, it's a chemical process that causes a controlled oxidation (a form of rust) on the surface of the steel, turning it black. Because it changes the steel itself rather than adding a layer on top, it doesn't affect the feel or weight of the club in any noticeable way.

This method has one major prerequisite, and it’s a big one: it only works on raw carbon steel or some stainless steel irons. It will not work on chrome-plated irons. A majority of modern game-improvement irons are chrome-plated for rust prevention and durability. Most forged "players" irons and wedges are often made from raw carbon steel (like 1020 or 1025) and are perfect candidates for this project. If you try to apply black oxide to a chrome-plated club, nothing will happen.

How to Tell if Your Irons Are Chrome-Plated

  • High Polish Finish: If your irons have a mirror-like, shiny finish, they are almost certainly chrome-plated.
  • Check the Specs: Do a quick search for your specific iron model (e.g., "TaylorMade Stealth Irons materials"). The manufacturer's website will usually state if the finish is chrome plating.
  • Magnet Test (for old clubs): If you have an old, rusty spot, clean it up. Magnetism doesn't differentiate well, but if you can see peeling or flaking around a damaged area, it's likely a plating.

If your clubs are chrome-plated, you’d first need to have them professionally stripped by sandblasting, which adds another step and cost. For that reason, this DIY guide is best suited for forged, raw carbon steel irons or wedges that are ready for refinishing.

Your DIY Toolkit: Gathering the Supplies

Ready to get started? Safety first. You’re working with chemicals, so do this in a well-ventilated area like a garage with the door open. Here’s what you’ll need:

  • Safety Gear: Nitrile gloves and safety glasses are non-negotiable.
  • Cleaning and Prep:
    • Acetone or a strong degreaser (like brake-cleaner spray).
    • Lots of paper towels or clean, lint-free rags.
    • A rust and lime dissolver (like CLR or Evapo-Rust) if you have any existing rust spots.
    • Fine steel wool (#0000) or a soft scouring pad for final prep.
  • Blackening Solution: Look for a reputable "cold blue" or black oxide solution. Birchwood Casey Perma Blue or Super Blue are trusted, widely available options.
  • Application:
    • A small glass or plastic container to pour the solution into. Do not dip clubs directly into the bottle.
    • Foam brushes, cotton balls, or small cut-up pieces of clean cloth for application.
  • Polishing and Sealing:
    • A high-quality gun oil (like Rem Oil or Ballistol).
    • Optionally, high-quality wax or a matte clear-coat enamel spray for extra protection.
  • Paint Fill (Optional): Testers model paint or Tamiya acrylics work great. You’ll also need nail polish remover (with acetone) to clean up excesses.

The Step-by-Step Guide to Blackening Your Irons

Patience and preparation are your best friends here. Rushing the prep work is the number one reason for a poor result. I recommend doing one club head start to finish to perfect your process before moving on to the entire set.

Step 1: Prep Work is 90% of the Job

The goal is to get the club head down to immaculately clean, bare metal. Any oil, dirt, or leftover finish will prevent the chemical reaction from happening.

1. A Deep, Thorough Clean

If you're not removing hosels, wrap painter's tape tightly around them to protect them. Begin by scrubbing the club head with hot soapy water and a brush to remove all loose dirt and grass. Dry it completely. Then, soak a clean rag in acetone and wipe down the entire head. Use gloves for this part! You want to remove every trace of oil, including the oils from your fingers.

2. Removing Old Finishes & Rust

If your raw-finish irons have an old black oxide finish or any rust, you’ll need to remove it. You can do this by soaking the club head in a rust remover like CLR or Evapo-Rust for about 30 minutes, or by carefully buffing stubborn spots with fine-grade steel wool and a bit of lubricant like WD-40. Once the old finish is gone, you must re-clean and degrease the head with acetone again to remove any residue from the rust remover lubricants.

3. The Final Degrease

Just before you apply the blackening solution, give the head ONE LAST wipe-down with a fresh, acetone-soaked rag. From this point on, do not touch the metal with your bare hands.

Step 2: Applying the Black Oxide Solution

This is where the transformation happens. Pour a small amount of the black oxide solution into your container.

  1. Using a foam brush or saturated cotton ball, apply a thin, even coat of the solution to the entire club head. Work quickly and methodically to cover every part.
  2. You will see the metal begin to change color almost immediately, turning a dark gray or black. Let the sclotion react for about 60-90 seconds. You don't want it to dry on the surface.
  3. Rinse the club head thoroughly under cold running water to stop the chemical reaction.
  4. Pat the head dry with a clean paper towel. At this point, the finish may took a little chalky or uneven. This is normal. Take your super-fine (#0000) steel wool and lightly buff the head. This is called 'carding' and it removes the loose, flaky layer of oxide, leaving a smoother, more uniform gray-black finish behind.
  5. Repeat the process. To achieve a deeper, richer black, you will need to apply 2-4 coats. Apply the solution, wait, rinse, dry, and lightly buff with steel wool between each coat until you love the color.

The more coats you apply, the darker the finish will become. Aim for a deep, even color across the entire head.

Step 3: Sealing and Protecting Your New Finish

Once you are satisfied with the black color, dry the club head completely. The fresh black oxide finish is vulnerable to moisture and flash rust until it’s sealed.

Apply a generous coat of gun oil over the entire head with a clean cloth. The oil will displace any lingering microscopic water molecules and penetrate the pores of the newly oxidized metal. Let the club sit, coated in oil, for at least a few hours or, ideally, overnight. After it has cured, wipe off all the excess oil with a clean, dry rag. The result should be a beautiful, satin-black finish with a subtle sheen.

Step 4: The Final Touch - Paint Fill

Your beautiful black irons are almost done, but you need to re-do the paint fill on the logos, numbers, and lettering. This detail makes the project pop.

  1. Choose your color(s) of acrylic model paint.
  2. Using a small brush or needle applicator, dab the paint into the engraved areas. You don’t have to be neat - it’s okay to have excess paint on the face of the club.
  3. Let the paint dry for 15-20 minutes.It doesn't need to be fully cured.
  4. Lightly soak a small patch of a paper towel with acetone or nail polish remover and gently wipe it across the flat surfaces of the club head. The remover will wipe the excess paint right off the head, but the paint inside the recessed engravings will remain perfectly filled.

Final Thoughts

Refinishing your own golf irons is a rewarding project that transforms your equipment from standard to custom. The success of the job hinges almost entirely on meticulous prep work, taking the extra time to achieve a perfectly clean, bare-metal surface will ensure a beautiful, lasting finish.
