Maintaining your waterproof jacket in excellent condition is crucial for its effectiveness against rain, wind, hail, and snow. Often, a thorough cleaning is all that's needed to restore its waterproof qualities. But how exactly should you go about this?
Most jackets have a care label attached, either directly in the jacket itself or on a card that accompanies it when purchased. Be sure to keep this card for future reference. Carefully read the care instructions on your jacket to ensure proper cleaning and avoid damaging the fabric.
Give the jacket a good shake, or gently brush it to remove any loose dirt and debris.
Secure all zippers, Velcro straps, studs, pulls or other closures on the jacket and hood to prevent any snags during washing.
Look for any tears or worn-out sections on your jacket. Repair these before washing to prevent exacerbating the damage.
If you are using a machine wash instead of hand washing, make sure you clean it thoroughly before use - more on that below.
Ordinary washing powders and laundry detergents that you use on your clothes can damage the waterproof coating on your jacket and leave residues that reduce breathability, so DO NOT use them.
For optimal results, it is recommended that you use a warm wash when cleaning your waterproof jacket, as this helps maintain the effectiveness of the waterproof coatings.
Use specialist detergents/cleaners specially designed for waterproof fabrics, such as Granger's Performance Wash or Nikwax Tech Wash. These products help preserve the durable water repellent (DWR) treatment on waterproof garments, which is essential for allowing water to bead and roll off, thereby maintaining the garment's performance. Dirt trapped in the garment's pores can significantly diminish the material’s waterproof capabilities.
Thoroughly clean the detergent drawer to eliminate any leftover detergent. My washing machine's drawer can be removed, allowing me to wash it in the sink. It's surprising how much detergent residue accumulates in, around, and beneath the drawer. While the drawer is out, take the opportunity to clean underneath it as well. The removal process varies across different washing machine brands, so consult your manual or watch a YouTube tutorial specific to your model.

With nothing in the washing machine, run a hot wash cycle without any washing powder/detergent to eliminate residual substances from past washes. Although it may seem wasteful to run an empty cycle, I've found it significantly enhances the effectiveness of the specialist detergent and reproofer.
Set the machine to the appropriate cycle and keep to the manufacturer's exact care details. In the absence of specific instructions, opt for a gentle cycle using cold or lukewarm water.
To wash your waterproof jacket, place it in the washing machine with a small amount of specialist detergent, such as Granger's Performance Wash or Nikwax Tech Wash. Refer to the detergent's instructions for the correct amount per garment.
Ensure that the washing machine is not overloaded, as this allows for proper rinsing. Opt for a gentle spin setting to help maintain the fabric's integrity, following the manufacturer's care instructions.
Opt for an additional rinse cycle to guarantee that all cleaning products are thoroughly removed.
Use cold or lukewarm water and mix in a specialist detergent, such as Granger's Performance Wash or Nikwax Tech Wash.
I usually let my mine soak in the basin, fully submerged in water and detergent, for approximately 5-10 minutes. Then, I gently rub with my hands to lift away any dirt.
Let the dirty water run away, then rinse the jacket under running water until all soap residue is eliminated.
Hang the jacket in a well-ventilated area, avoiding direct sunlight. Using a hanger helps the jacket retain its shape and prevent unwanted creases. Remember to ensure the drying area is clean and free from dust or debris that might cling to the damp fabric.
If the care label permits, you can tumble dry them on a low heat setting. This process can help reactivate the water-repellent coating.

Properly washing and reproofing waterproof jackets is crucial for preserving their functionality and extending their lifespan.
To reproof a waterproof jacket, I use wash-in treatments, which I find are more effective than spray options for re-proofing the whole jacket. Simply add these to the washing machine for comprehensive coverage of the entire garment. My top picks and most used are Granger's Clothing Repel and Nikwax TX Direct.
To reproof a waterproof jacket using spray-on products, a waterproofing spray is perfect for addressing specific sections of the jacket that experience the most wear and tear. I typically opt for a waterproofing spray like Granger's Performance Repel Plus and Nikwax TX Direct Spray-on Waterproofer. After the jacket has been washed, I sometimes use the spray on higher-wear areas of the jacket between doing a full reproof with the wash-in treatment.
After washing, you need to know how to reproof a waterproof jacket.
If you reproof a waterproof jacket, always do it after washing it to ensure the fabric is free of dirt and residues. This step is crucial for ensuring the reproofing process is as effective as possible.
If the manufacturer's care instructions allow, use a tumble dryer on a low heat setting, as heat can help activate the waterproofing. Alternatively, air dry the jacket indoors or outdoors on a washing line, but not in direct sun.
To wash and re proof at the same time, I use Granger's Wash + Repel, a combined cleaner and proofer. It's like the 'Wash & Go' of waterproof care!
If the care instructions permit machine washing, add 100ml of the product to the detergent drawer and proceed with the recommended washing cycle. When washing multiple garments simultaneously, increase the amount by 50ml for each additional item.
However, I usually don't wash or proof more than two garments at a time to ensure ample space for proper cleaning. This method is also effective for maintaining other waterproof gear, such as waterproof trousers.
Then dry as above. Grangers recommends that you do that if your product can be tumbled-dried as per the manufacturer's care instructions. Grangers says that all Grangers protection products are effective when air-dried. However, they recommend applying a small amount of heat, such as in a tumble dryer or using a hair dryer, for optimum durability.
I typically wash mine after heavy use or when they appear visibly dirty. If you wear your jacket frequently, it's essential to clean it regularly and adhere to the care label instructions to preserve its effectiveness and extend its lifespan.

The waterproofing will deteriorate over time, but washing too frequently or infrequently, letting dirt/chemicals build up, or washing it incorrectly, can speed this up and lead to delamination.
I typically reproof mine about every four washes or whenever I notice that water no longer beads on its surface. It's usually apparent when wearing the jacket if it requires reproofing. Basically, it stops repelling water.

While ordinary detergents or washing powder may clean your jacket, they will also strip away its waterproofing properties and stop repelling water. Therefore, it is crucial to use a specialist cleaning product designed specifically for waterproof garments.
Fabric softeners and conditioners contain chemicals that can clog the pores in the jacket's waterproof membrane, significantly reducing its water-repellency. The fabric softeners can also leave a residue that attracts dirt and grime, further compromising the jacket's performance. This build-up can also affect the jacket's breathability, making it less comfortable to wear during your outdoor adventures.
Excessive heat can damage the jacket's fabric, compromising its waterproof membrane and reducing its ability to repel water effectively. High temperatures can also cause the water-repellent coating to break down, leading to a loss of the jacket's durable water repellency (DWR) over time. This can make the jacket more susceptible to wear and tear, ultimately shortening the lifespan of your waterproof garment.
Residual soap can compromise waterproofing. When washing waterproof jackets, it's crucial to ensure that all soap residues are thoroughly rinsed out. Leftover detergent can clog the pores of the waterproof membrane, reducing its breathability and ability to repel water effectively.
Always read the manufacturers' care labels. Washing waterproof jackets is crucial for ensuring the waterproofing is effectively restored and the garment remains in optimal condition. Proper care and maintenance of waterproof gear, including using specialised cleaners and periodic reproofing, are essential to ensure optimal performance and longevity and maintain your jacket's DWR.
All the above also basically applies to waterproof trousers.
When you're out on a walk or hike, it's crucial to know how to carry out basic repairs and maintenance on your waterproof jacket to ensure it continues to perform at its best. Here are some tips to help you maintain it in excellent condition:
Gently brush it with a soft-bristle brush to remove dirt and debris. While you might not have one during your walk, keep one in your car for when you return.
If you spot any tears or holes, promptly repair them using a patch kit or waterproof repair tape. This quick fix will prevent further damage and help maintain the jacket's waterproof capabilities.
Iron-on tapes are available, but I use and recommend McNett Tenacious Tape Fabric and Seam Repair, as iron-on tapes are completely impractical if you are out on a walk. I also take a small roll of waterproof gaffer tape in my first aid kit.
Regularly inspect your jacket's zips and seams for signs of wear and tear. Repair or replace them as necessary to keep your jacket fully functional.
Professional options are available if your waterproof clothing is damaged beyond your repair capabilities or if you're uncomfortable attempting repairs yourself. Consider the following:
Many manufacturers provide product repair services. Check your warranty or contact the manufacturer's customer service department for repair services.
Many outdoor gear repair shops offer services like mending tears or replacing zippers.
If you have access to a local tailor or seamstress specialising in outdoor gear, they might be able to repair your waterproof clothing.
Store your waterproof jacket in a cool, dry place. To maintain the fabric's integrity, avoid cramming it into tight spaces.
It's important to hang your jacket on a sturdy hanger to help it retain its shape and prevent unwanted creases.
Ensure the storage area is free from direct sunlight, as prolonged exposure can weaken the fabric and cause colours to fade. Additionally, avoid placing heavy items on your jacket, which could compress the insulation and affect its performance.
Regularly inspect your storage space for any signs of moisture or pests that could harm your jacket over time. By taking these precautions, you can ensure it remains in excellent condition and ready for your next outdoor adventure.
Maintaining and reproofing your waterproof jacket is simpler than it seems. The correct products and methods can prolong its lifespan and ensure it functions optimally. Use this step-by-step guide on how to wash a waterproof jacket to ensure it is prepared for any weather conditions.
