How to Wash Golf Waterproofs

Dumping your expensive waterproof gear into a standard wash cycle is one of the fastest ways to ruin it. Proper cleaning not only gets rid of the mud and sweat but is essential for restoring its ability to keep you dry on the course. This guide will walk you through the correct, step-by-step process for washing your golf waterproofs, explaining how to reactivate their performance and avoid common mistakes that can destroy them.

Understanding Your Waterproof Gear (And Why You Can't Just Wing It)

Before we touch the washing machine, it's helpful to understand what 'waterproof' actually means in the context of your golf jacket or pants. It's not just a single layer of fabric. Modern waterproofs are a technical system with two main components working together:

• The Waterproof Membrane: This is the workhorse. Think of layers like Gore-Tex or other proprietary brands. It's a high-tech inner layer with microscopic pores that are small enough to block large water droplets (rain), but large enough to let small water vapor molecules (your sweat) escape. This is what makes a garment both waterproof and breathable. This membrane is delicate. Harsh chemicals and high heat can clog these pores or cause them to delaminate (separate) from the outer fabric, rendering the garment useless.
• The DWR Coating: This stands for Durable Water Repellent. It's an invisible chemical treatment applied to the outside of the fabric. The DWR isn't what makes the garment waterproof, but it's critically important. Its job is to make water bead up and roll right off the surface, preventing the outer fabric from becoming saturated. When working correctly, you'll see those perfect little spheres of water on your jacket. When the DWR fails, the outer fabric gets heavy and waterlogged - a condition called 'wetting out'. Even though the membrane underneath is still keeping water out, a 'wetted out' garment feels cold, clammy, and its breathability grinds to a halt because the sweat vapor has nowhere to go.

Standard laundry detergents are the enemy of this system. Their chemistry is designed to break down oils and lift dirt, which is great for a cotton t-shirt but terrible for DWR. These detergents contain surfactants and wetting agents that strip away the DWR coating. Fabric softeners are even worse, as they leave behind a hydrophilic (water-attracting) residue that actively helps the fabric absorb water. This is why knowing the right way to wash your gear isn't just a suggestion - it's what preserves its function and value.

Your Gear Cleaning Toolkit

The good news is you don't need a professional lab to do this. A few specific items will get the job done right and protect your investment.

• A Specialized Tech Wash: This is a non-negotiable. Products like Nikwax Tech Wash or Grangers Performance Wash are specifically designed to clean high-performance gear without damaging the DWR or waterproof membrane. They lift dirt and grime effectively while rinsing away completely, leaving no residue behind.
• A Soft-Bristled Brush or Cloth: For pre-treating any heavily soiled areas, like mud splatters around the cuffs or hem.
• A Washing Machine: Any standard machine will do.
• A Heat Source: A tumble dryer is ideal, but an iron and a protective towel will also work perfectly. This step is for reactivating the DWR finish after washing.
• DWR Revitalizer (Optional but Recommended): For older garments whose DWR is wearing thin. A spray-on product like Nikwax TX.Direct Spray-On or Grangers Performance Repel Plus can bring them back to life.

The Step-by-Step Washing Guide

Follow these steps closely, and your waterproof gear will come out clean, fresh, and ready for another rainy day on the links.

Step 1: Preparation is Key

Don't just toss it in the machine. A few minutes of prep makes a world of difference.

• Empty the Pockets: Check every single pocket for scorecards, tees, ball markers, or that rogue half-eaten granola bar.
• Brush Off Debris: If your gear is splattered with dried mud or grass, take a soft brush or a dry cloth and gently brush off as much of it as you can. This prevents your wash water from becoming a muddy mess.
• Zip It Up: Close all zippers, including the main zip, pockets, and any pit-zips. Fasten any Velcro straps on cuffs or storm flaps. This prevents them from snagging on the delicate inner lining or the drum of the machine.
• Clean the Detergent Dispenser: This is a sneaky but important step. Pull out your washing machine's detergent drawer and give it a good clean with hot water and a brush. You want to remove all traces of old, conventional detergent and farbic softener residue that could otherwise get washed into your waterproofs.

Step 2: The Wash Cycle

Now you're ready to put your gear in the machine. Less is more here - don't overload it. Wash one or two items at a time.

• Read the Care Label: Always start by checking the manufacturer's care instructions inside the garment. They will give you the recommended temperature and cycle settings. Most will say something like 30°C or 40°C (roughly 85°F to 105°F), a gentle or synthetics cycle.
• Add the Tech Wash: Following the directions on the bottle, pour the correct amount of specialized cleaner (like Nikwax Tech Wash) directly into the now-clean detergent drawer. Never use standard powder or liquid detergent.
• Set the Machine: Select a gentle, low-spin cycle. A "synthetics" or "delicates" setting usually works well. Use warm water, not hot. Hot water can damage the seam tape and membranes.
• Consider an Extra Rinse: If your machine has the option, running a second rinse cycle helps guarantee that all the cleaning solution has been washed away, leaving the fabric perfectly prepped for the all-important next step.

The Most Important Step: Reactivating the DWR Coating

Your gear is clean, but it's not "ready" yet. The gentle laundry cycle doesn't damage the DWR, but it does need to be ‘woken up’ with a bit of gentle heat to get it working again. This process resets the chemical bonds and allows the finish to properly repel water.

Method 1: The Tumble Dryer (The Easy Way)

Again, first check the care label on your garment to confirm it can be tumble-dried. Most technical gear can handle it on a low setting.

• Toss the clean, damp garment into the dryer.
• Tumble dry on a low or medium heat for about 20-30 minutes. High heat can melt fabrics and ruin seam seals, so stick to the lower setting.
• When it's done, the garment should be dry and the DWR will be fully reactivated. You can test it by flicking a few drops of water on the sleeve - they should bead up perfectly.

Method 2: The Ironing Approach (No Dryer? No Problem)

If you don't have a tumble dryer or your garment's label advises against it, an iron is your best friend.

• Hang your clean garment to air-dry completely or until it's just slightly damp.
• Lay the item flat on an ironing board and place a thin towel or cloth over it. Never apply the iron directly to the waterproof fabric.
• Set your iron to a low heat setting (often "synthetics" or a single dot • symbol) and make sure the steam function is turned off.
• Gently iron through the towel, moving constantly. Spend a little extra time on high-wear areas like the shoulders and cuffs, as this is where the DWR often gets worn down first. The gentle, even heat will do the same job as the tumble dryer.

When to Re-Proof: Bringing Old Gear Back to Life

Over time and with use - things like a golf bag strap rubbing on your shoulder - the factory DWR coating will eventually wear off. You’ll know this is happening when water stops beading and the outer fabric starts absorbing moisture, looking dark and soaked. This is when that 'wetting out' occurs.

No amount of washing and heat-treating will fix an absent DWR. You need to apply a new one. Here’s how:

1. Wash It First: Always start by washing the garment with a technical cleaner, following all the steps above. A clean surface is necessary for the new DWR treatment to bond properly. Do not dry it yet. The treatment is best applied to a damp garment.
2. Choose Your Proofer: You can get a wash-in or a spray-on proofer. I usually recommend a spray-on proofer because it lets you target the outside of the garment where it's needed, without affecting the breathability of the inner lining.
3. Apply The Proofer: Hang the clean, damp garment on a hanger. Spray the re-proofer evenly across the entire outer surface from about 6 inches away. Pay special attention to the shoulders, zippered areas, and sleeve cuffs.
4. Wipe Off Excess: Use a damp cloth to wipe away any drips or excess spray to prevent white marks from forming later.
5. Activate with Heat: Now you need to treat it just like a freshly washed item. Use either the tumble dryer on low heat or the iron-and-towel method described above to heat-activate the new DWR coating and bond it to the fabric.

This re-proofing process can dramatically extend the life of your gear, making a ten-year-old jacket perform like it did on day one.

Final Thoughts

Properly caring for your golf waterproofs isn't hard, it just requires doing things a little differently. By using a specialized tech wash instead of regular detergent and always finishing with a low-heat treatment - either in a dryer or with an iron - you can keep your gear performing at its best for many seasons to come.
