How to re-waterproof a waterproof jacket or coat

Over time, even the most reliable waterproof gear can lose its waterproof-ness (technical term), so, if you’ve noticed your waterproof jacket is getting a little soggier than usual on your outdoor adventures, it’s probably time to reproof it.

Here’s What You’ll Need:


Step 1: Clean Your Jacket By Hand

Before re-waterproofing your jacket, it's essential to give it a thorough clean by hand to get rid of the dirt and oils that build up on the fabric, which is the main culprit behind your jacket’s temporary loss of waterproof power! Use a soft brush to remove any dirt and grime, paying particular attention to areas like the cuffs, collar, and seams. Once cleaned, rinse it out and set aside.

NB: It’s always best to do this by hand, so our advice is to avoid putting your jacket in the washing machine with other clothes and detergents for this bit, as the washing machine bit comes after.

Step 2: Get Your Waterproof Product

When it comes to re-waterproofing your jacket, not all products are created equal, which is why we only recommend what we know and love. We’ve partnered with Grangers, as we trust them to deliver exceptional results, which after many trials with many waterproof garments, they always do!

For the best reproofing product, we highly recommend the Grangers clothing repel wash-in liquid, as it contains special ingredients that restore the waterproof coating on your jacket, ensuring maximum protection against rain and moisture.

Step 3: The Washing Machine Bit

Follow these instructions for the best results:

  • Use 2 x 50ml caps (100ml) per item (add 50ml for every additional item)
  • For best results, we recommend reproofing garments separately
  • Pour product directly into the detergent drawer of your washing machine
  • Wash on a full cycle at 30°C/86°F or according to care label instructions
  • Air-dry or tumble-dry if care label permits


Step 4: Test Your Jacket

Once your jacket has dried completely, it's time to put it to the test. Grab a water bottle or hose and spray water onto the surface of your jacket. If the water beads up and rolls off the fabric, congratulations – your jacket is now waterproof!

What Happens If It Doesn’t Work?

If the water starts to soak into the fabric or forms puddles, it could be a sign that your jacket has lived its best days and it’s time to consider buying a new one. If that’s the case, then here are the TOG24 design team’s top picks:
