Can you wash a waterproof jacket?

Yes you can! In fact, washing a waterproof jacket is an important part of keeping it working at its best. Dirt and oils (including those from your own body) inhibit the action of the DWR. You mustn’t use standard detergent, though. Get your hands on some detergent for waterproof clothing, like Grangers or Nikwax. Then follow our steps below on how to best wash your waterproof jacket.

Before washing

  • Give your garment a good old brush. Get rid of any loose mud or dirt.
  • Close zips and flaps.
  • Ensure the detergent compartment of your machine is clean of any detergent.
  • (You may also wish to run your washing machine on a hot wash with nothing in it to clear any residues from detergent or softeners).

Washing

  • Pour the waterproof washing liquid into the detergent compartment. Read the detergent bottle to see what’s the appropriate dose for your garments and your machine.
  • Pop your waterproof garments in the drum. You should only put waterproof clothing in. Don’t put in more than two garments at a time.
  • Check the label of your garment for exact care details. Typically, you run through the complete wash and rinse cycle at 30 degrees.

After washing, you can air dry or tumble dry your garments. Check the care instructions, but you typically should only go for low or medium heat.

In fact, heat treating your garment after washing or reproofing helps the DWR perform better. You could use an iron on your waterproofs to achieve this effect!

How often should I wash my waterproof jacket?

Whenever it gets dirty, basically! We recommend about every three to four months – but it, of course, depends on how much you’re using your jacket. If you're not often going out in the wet, twice a year should be enough. You can time it for the start and end of the rainy season!
