How to Clean Mold Off Golf Clubs

By Spencer Lanoue
July 24, 2025

Discovering mold on your golf clubs can feel like a punch to the gut, but it's a far more common problem than you might think. All it takes is one damp round and a forgotten bag in a dark corner for that fuzzy, unwelcome guest to appear. The good news is that cleaning it off is completely manageable, and this guide will walk you through every step to restore your clubs to their former glory. We’ll cover cleaning the heads, grips, and shafts, plus how to tackle the source of the problem - your golf bag - and make sure it never happens again.

Understanding the Enemy: Why Mold Loves Your Golf Gear

Before we get into the cleaning, it helps to understand what you're up against. Mold is a fungus, and it thrives in dark, damp, and poorly ventilated environments. Sound familiar? It’s the exact description of a golf bag stored in a car trunk, a garage corner, or a basement closet after a drizzly day on the course.

The organic materials in your bag, grips, and even small bits of grass or dirt stuck in your club grooves provide the perfect food source. When you combine moisture (from rain, dew, or humidity) with darkness and a food source, you've rolled out the red carpet for mold. The key to winning this battle isn't just cleaning up the current mess, but creating an environment where it can't come back.

Gather Your Mold-Fighting Toolkit

You don’t need a specialized laboratory to get this done. Most of what you’ll need is probably already in your house. Here’s a simple checklist of what to gather before you start:

  • A bucket large enough to submerge your iron heads
  • Warm water
  • Mild dish soap (like Dawn)
  • White distilled vinegar (a fantastic natural mold killer)
  • A soft-bristled brush (an old toothbrush or a vegetable brush is perfect)
  • Several clean, dry microfiber towels
  • A soft sponge
  • (Optional) A can of compressed air for nooks and crannies

The Mold Removal Playbook: A Step-by-Step Guide

Got your supplies ready? Let's get to work. It’s best to do this outside or in a well-ventilated area like a garage with the door open. We'll work our way from the heads down to the grips.

Step 1: Tackle the Club Heads

The club heads are usually where you first spot the problem, especially in the grooves of your irons and wedges. The approach is slightly different for irons versus woods.

For Irons and Wedges:

  1. Fill your bucket with warm water and a good squirt of dish soap. For extra mold-killing power, add about one cup of white vinegar to the bucket and swish it around.
  2. Place your irons and wedges headfirst into the bucket, making sure the water covers the entire head but stops below the ferrule (the little plastic piece connecting the head to the shaft). Submerging the ferrule for too long can weaken the epoxy holding the head onto the shaft. Let them soak for 10-15 minutes to loosen the grime and kill the mold spores.
  3. One by one, take a club out of the water. Dip your soft brush into the soapy water and scrub the entire club head, paying special attention to the grooves. Use the bristles to really get in there and clear out any gunk. Don’t just scrub the face, clean the back and sole of the club, too.
  4. Rinse each head thoroughly with clean water. Check the grooves to make sure they're completely clean. If not, give them another quick scrub.

For Woods, Hybrids, and Your Putter:

These clubs shouldn't be soaked. Many modern woods and hybrids have hollow components and detailed constructions that can be damaged by full submersion. Drivers, especially, often have screw ports for adjustable weights that aren't meant to be underwater.

  1. Instead of soaking, dip your soft brush or sponge directly into your soapy vinegar-water solution.
  2. Gently scrub the face, sole, and crown of the club. Be careful not to be too aggressive, especially on the painted crown of a driver or wood, to avoid scratches.
  3. Use a damp microfiber towel to wipe away the suds and residue. You may need to rinse the towel a few times to get the club totally clean.

Step 2: Clean the Shafts

Mold on the shafts is less common but can happen. Whether you have steel or graphite shafts, the process is simple and similar.

  1. Take a clean microfiber towel or sponge and dip it in your cleaning solution. Wring it out so it's damp, not soaking wet.
  2. Wipe down the entire length of the shaft, from the ferrule up to the grip. The vinegar in the solution will handle any mildew spots effectively.
  3. Using another clean, dry microfiber towel, immediately dry the shaft completely. This is very important for steel shafts to prevent any surface rust from forming.

Step 3: Disinfecting the Grips (The Most Important Part)

This is where many golfers go wrong. The grips are porous and can hold a lot of moisture and mold spores deep within the rubber or cord. If you don't clean the grips properly, the mold will just come right back. This is also a good time to restore some of their natural tackiness!

  1. Refill your bucket with a fresh mix, but this time go lighter on the soap and a little heavier on the vinegar if the mold is significant. A 50/50 mix of warm water and white vinegar works great.
  2. Do not submerge the grips. This can trap water inside the shafts through the small hole at the end of the grip, leading to rust from the inside out.
  3. Dip your soft-bristled brush into the solution and gently scrub the entire surface of the grip. Work in circular motions and then up and down the length of the grip. You'll likely see a lot of dirt come off along with the mold.
  4. Rinse the grip under a gentle stream of plain water, rotating the club to wash all sides. Be careful to point the club head-down so water runs away from the shaft and doesn't get inside.
  5. This is the step that makes all the difference: drying. First, take a dry towel and squeeze the grip firmly to absorb most of the water. Then, either stand the clubs up (grip-end up) in a well-ventilated area or hang them somewhere to air dry completely. Don't put them back in the bag until they are 100% dry to the touch. This may take several hours or even overnight.

Step 4: The Final Polish and Dry Off

Once everything is clean, give all your clubs one final wipe-down with a dry microfiber cloth before you put them away. Make sure every part of the club - head, hosel, shaft, and ferrule - is totally dry. This prevents water spots and any lingering moisture that could invite rust or mold back.

The Root of the Problem: Cleaning Your Golf Bag

You can do the world’s best job of cleaning your clubs, but if you put them back into a moldy bag, you’ll be fighting this same battle again in a few weeks. The bag is almost always the source of the infestation.

  1. Empty Everything: Take everything out of your bag. Balls, tees, gloves, half-eaten granola bars, scorecards - everything. Unzip every single pocket.
  2. Vacuum: Use a shop-vac or a vacuum with a hose attachment to suck out all the loose dirt, sand, and grass from every pocket and corner of the bag.
  3. Wipe Down: Make a solution of warm water and white vinegar (a little dish soap is okay too). Use a sponge or towel to wipe down the entire bag, inside and out. Pay special attention to the interior of the pockets and the fuzzy club dividers, which are prime real estate for mold.
  4. Air Dry Completely: The most crucial step. Place your bag in a well-ventilated, sunny spot to dry out. The sunlight is a natural disinfectant and helps kill any remaining mold spores. Leave it open with all pockets unzipped for at least 24-48 hours, or until it's bone-dry. Do not rush this step.

Preventative Maintenance: How to Keep Mold Away for Good

An ounce of prevention is worth a pound of cure. Now that your gear is sparkling clean, let's keep it that way.

  • Dry After Every Wet Round: If you play in the rain or an early morning dew, take a few minutes when you get home. Take your clubs out of the bag and wipe them down. Leave the bag open to air out.
  • Don't Store It in a Trunk: A car trunk is a hot, humid, and dark box - the perfect mold incubator. Store your bag in a dry, ventilated "caddy corner" in your house or garage.
  • Air Out Pockets: After a round, unzip a few pockets to let air circulate, especially the one where you keep your glove.
  • Toss in a few silica gel packets (the kind you find in new shoe boxes) into your bag’s larger pockets to help absorb excess moisture.
