Before you wash your waterproof jacket

  • Remove any big, obvious stains with a damp cloth.

  • Use a specialised wash like Grangers Performance Wash.

  • Set the washing machine to 86 degrees Celsius Fahrenheit, and select your standard washing program.

  • Depending on the advice on your care label, your garment can either air dry or tumble dry. Follow the instructions for the best results.

Things to avoid:

  • Fabric softener. To minimise damage, stick to a specialised detergent for the best results.
  • The dry cleaner. The solvents they use in the dry cleaning process can damage your jacket.
