How to Wash a Waterproof Jacket

Yes. If you follow the basic rules of washing and re-treating waterproof garments it is completely okay to do.

Our guide to washing a waterproof jacket, or any waterproof garment, will ensure your kit is in peak condition. This advice applies to all waterproof fabrics such as GORE-TEX, DryVent, Pertex Shield or e-Vent.

All waterproof clothing has a Durable Water Repellent (DWR) treatment. It makes water bead and roll off the fabric, but wears off with time and use.

Don't use standard detergent or fabric conditioner as this will harm the garment's performance. Grangers make specialised detergents and treatments for waterproof clothing.

If any internal taped seams have detached, hand-wash and once dry reattach with seam sealant. Once you have repaired the seams, wash and reproof as per instruction

Products needed:

• Grangers Wash + Repel Clothing 2 in 1, or Grangers Performance Wash Concentrate

• Grangers Clothing Repel (wash-in) or Grangers Performance Repel Plus (spray-on)

The product(s) you use will depend on how much time you have:

• If you are short on time, choose Wash + Repel Clothing 2 in 1

• For a more thorough clean and reproof, choose Performance Wash Concentrate and then follow with Clothing Repel (wash-in) or Performance Repel Plus (spray-on)

• If your jacket has a fabric inner, you may prefer the spray-on proofer so as not to coat the lining
